ABSTRACT. 互联网新闻已被很多研究用于物价指数的监测和预测。但在对于某一分类别物价的舆情指数构建过程中,经常会出现舆情观点新闻缺失的问题。在对没有舆情讨论的时点的舆情数据进行数据补齐的时候,不仅需要考虑该缺失数据时点前后的舆情值,同时也要考虑该时点其他相关主题的舆情值。为了更好地刻画不同相关主题下新闻舆情之间的复杂关联关系,本文提出了一种基于图神经网络自学习模型(AGNN)的舆情指数网络构建方法。这种方法将九个食品相关舆情指数作为网络节点,相应的量化后的日度舆情观点值作为时间序列,设计了一个图神经网络模型对存在的隐性图结构进行学习,构建成动态舆情指数网络,实现对于稀疏的细项新闻观点取值的补齐。为验证所提出的舆情指数网络模型的有效性,我们利用所提出的基于AGNN舆情指数网络的模型对各个食品分类相关的新闻观点数据缺失进行填补,并将其用于消费者价格指数食品项的预测。与其他数据补齐方式相比,我们经过我们提出的模型补齐的舆情数据对食品价格的预测精度提升最大。可见,本研究所提出的舆情指数网络模型能够更有效地刻画食品相关不同主题下,该方法对于其他类似的舆情指数集合建模问题也有一定的借鉴价值。

ABSTRACT. Deep learning (DL) models have significantly improved the performance of text classification and text regression tasks. However, DL models are often strikingly vulnerable to adversarial attacks. Many researchers have aimed to develop adversarial attacks against DL models in realistic black-box settings (i.e., assumes no model knowledge is accessible to attackers) that typically operate with a two-phase framework: (1) sensitivity estimation through gradient-based or deletion-based methods to evaluate the sensitivity of each token to the prediction of the target model, and (2) perturbation execution to craft adversarial examples based on the estimated token sensitivity. However, gradient-based and deletion-based methods used to estimate sensitivity often face issues of capturing the directionality of tokens and overlapping token sensitivities, respectively. In this study, we propose a novel eXplanation-based method for Adversarial Text Attacks (XATA) that leverages additive feature attribution explainable methods, namely LIME or SHAP, to measure the sensitivity of input tokens when crafting black-box adversarial attacks on DL models performing text classification or text regression. We evaluated XATA’s attack performance on DL models executing text classification on three datasets (IMDB Movie Review, Yelp Reviews-Polarity, and Amazon Reviews-Polarity) and DL models conducting text regression on three datasets (My Personality, Drug Review, and CommonLit Readability). The proposed XATA outperformed the existing gradient-based and deletion-based adversarial attack baselines in both tasks. These findings indicate that the ever-growing research focused on improving the explainability of DL models with additive feature attribution explainable methods can provide attackers with weapons to launch targeted adversarial attacks.

ABSTRACT. There exists an algorithm paradox which scholars have still not paid attention to in the gig economy. This paper builds a moderated-mediation model to explore and validate the specific boundary condition and impact mechanism of such an algorithm paradox. Results based on 314 data collected from Chinese gig workers find that, algorithmic monitoring can enhance gig workers’ organizational identification, but through the mediating effect of job flexibility, algorithmic monitoring can indirectly decrease gig workers’ organizational identification. Criteria control can not only mitigate the negative relationship between algorithmic monitoring and job flexibility, but also mitigate the negative relationship between algorithmic monitoring and organizational identification mediated by job flexibility. These findings prove the reality of the algorithm paradox and discuss theoretical and practical implications about how to enhance gig workers to identify with the platform.
ABSTRACT. In this paper, we investigate a two-echelon fresh product supply chain composed of a supplier and a distributor. The expression of preservation effort and order quantity are obtained under three kinds of preservation investment methods, as well as the intrinsic correlation mechanism among these decisions. With the aim of maximizing profit, the optimal preservation decision is made. This study shows that, joint investment in preservation is always the best way for both parties. When the gap between wholesale price and produce cost is small, the joint investment of supplier and distributor can be approximately equivalent to the investment of distributor alone. Therefore, distributors should take the initiative to undertake the preservation investment in order to maximize profits, while suppliers should avoid undertaking the investment alone.

ABSTRACT. Although mobile promotions are still a major marketing method in recent years, conversion rates for mobile promotions are not very high. How to improve the effectiveness of mobile promotion is still a challenge for company. Based on probability distance and construal level theory, this paper explores the influence of construal-matching effect on consumer repurchase behavior by using the large-scale field experiment in a low-cost airlines. The results show that the matching between low probability distance and high construal level has a significant negative effect on consumer repurchase behavior, while the matching between high probability distance and low construal level has a significant positive effect on consumer repurchase behavior. The differences of this result and the construal-matching effect are discussed. Furthermore, the moderating effects of probability distance and individual characteristics on matching effect also are discussed. This research has guiding significance for marketing, consumer relationship management, and customized service strategy.

ABSTRACT. Consumer purchase prediction is very important for strategy formulation and consumer segmentation. In particular, airlines have to target groups before implementing the operational strategy with the competition increases. However, due to the higher dimensions and a large number data missing in airlines, how to effectively predict the repurchase of consumers has become an urgent problem. This paper proposes a novel ensemble algorithm framework for predicting the binary classification based on evidence theory. The results show that the accuracy of the ensemble algorithm based on evidence theory is more than 90% using the public datasets. Further, this paper uses this algorithm model to predict the repurchase possibility of consumers in airlines. The results show that the performance and accuracy of this algorithm are improved compared with common used ensemble algorithms. This study has guiding and theoretical significance for consumer purchase prediction, the application of evidence theory and precision marketing

ABSTRACT. Despite members is high social identity and more loyalty to a product or brand, the existing marketing literatures offers little guidance on how to promote members’ actual purchase behavior based on the matching consistency and construal level theory. To address this gap, the current research examines that the matching consistency effect between predicted purchase probability and the construal level of promotions advertising on the repurchase behavior of members based on a large field experiment in airlines. The findings show that the matching effect between promotional messages with concrete or feasibility information and high purchase probability has more likely to promote members' repurchase behavior, while the matching effect between promotional messages with abstract or desirability information and low purchase probability has not any influence on members' repurchase behavior. This study has theoretical and practical guiding for the researches on marketing and customer management.

ABSTRACT. A large number of players purchase superior virtual gear to increase their chances of winning a battle. However, the design of PvP games, particularly the design of the competitive balance among players, remains largely unexplored. We consider an optimal product line design problem that allows the developer to design the competitive balance. Results indicate that tournament design enables the developer to alleviate the well-known cannibalization effect caused by the release of free versions through multi-dimensional versioning, which renders the freemium strategy optimal for the game developer. Second, tournament design allows the developer to overcome players' budget constraints. Specifically, the developer can effectively monetize the participation of players who play the game for free by handicapping them through tournament design and charging the paying players a higher price. Counterintuitively, tournament design results in a Pareto improvement in the sense that it increases the developer's profits and benefits every player.

ABSTRACT. On mobile apps platforms, management responses enable developers to spotlight customer feedback and then react accordingly. Aiming to understand management responses in digital innovation, we develop a theoretical model of attention-allocation that addresses an underexplored but essential question: In a digital system, how is spotlighted customer feedback absorbed into the following innovation, and what role do management responses play in this absorption? To answer the questions, we first identify the spotlighted customer feedback, relevant management responses, and the subsequent mobile apps updates on the Apple iOS platform. Secondly, text mining algorithms are developed to analyze the feedback and responses, and then measure stimulus-driven attention, goal-oriented attention, and the knowledge absorption in subsequent updates. The empirical results reveal that responding to maintenance and functional customer feedback improves the subsequent knowledge absorption in mobile updates. Additionally, absorbing knowledge from customer feedback is also improved if developers customize and post actionable response.

ABSTRACT. This paper seeks to investigate the predictive value of investors' intra-day social media discussions on firm risk. We conduct a textual analysis of user-generated content (UGC) to extract the volume (e.g., number of posts, comments, views) and valence (e.g., helpfulness, sentiment, opinion, topic dispersion) characteristics. Various predictive models based on machine learning methods are utilized to evaluate the predictive performance of UGC. The results indicate that both UGC valence and volume can provide additional predictive gains over the baseline model. More importantly, UGC valence can significantly outperform UGC volume in predicting firm risk. Besides, we find that UGC during the non-trading period of a day shows significantly better predictive performance as compared with UGC generated during the trading time. This suggests that social media discussions generated in the non-trading hours are more informative and value-relevant to investors, whereas there is excessive noise on social media during the trading hours.

ABSTRACT. The booming of online platforms has attracted academia’s increasing interest in cross-platform spillover of product consumption. This study investigates how physicians’ content creation in Tik Tok influences patients’ demands, comments and satisfaction towards the physicians on online health communities (OHCs). Using the difference-in-differences approach, we uncover asymmetric influences of cross-platform spillovers for high- and low-awareness physicians in Tik Tok. Specifically, low-awareness physicians do not enjoy the benefits (i.e., the increased volume of orders and comments on OHC) from content creation in Tik Tok, but their ratings turn to decline due to attention distraction caused by cross-platform activities. Conversely, for high-awareness physicians, we find a positive cross-platform spillover effect for orders and comments on OHC without decreasing their ratings. Despite the existence of attention distraction from cross-platform services for high-awareness physicians, the negative impact on feedbacks is offset by higher ratings from their cross-platform consumers.

ABSTRACT. Traditional machine learning methods have been widely applied to identify the determinants of depression in the elderly, while the lack of explainability of machine learning has been a long-standing limitation. Based on the 2018 China Health and Retirement Longitudinal Study, we combine the SHAP interpretation method with the LightGBM machine learning model to study the influencing factors of depression in the elderly. Results show that health status, socioeconomic status, family support, family structure, and social interaction are of key importance in identifying depression in the elderly. This study helps to demonstrate the effectiveness of SHAP in ranking influencing factors of depression in the elderly, and the results provide valuable practical insights in the prevention of depression in elderly.

ABSTRACT. Information technology has shown great potential in healthcare, especially in chronic disease management. In this paper, we leverage rational addiction model to investigate patients’ behavioral dynamic relationship in the context of IT-enabled diabetes self-management. We firstly build an analytical model to capture the impact of patients’ online learning behavior on their health outcome and the patients’ decision making about their self-management behaviors, then utilize a real-world data to empirically test the hypotheses. The GMM estimator of dynamic panel data model demonstrates the rational forward-looking behaviors generally exist in patients with diabetes, but they exhibit heterogeneous patterns depending on their demographics such as age, disease duration and gender. We contribute to the literature of IT-enabled chronic disease management, and also extend the application context of rational addiction model.

ABSTRACT. Academic social networking sites provide a simple avenue for researchers to exchange information. However, the mechanism by which question-related characteristics affect the answer outcome in academic social Q&A (SQA) is still unclear. This study focuses on how different combinations of question-related characteristics affect answer outcomes in ResearchGate based on a configurational perspective. The study adopts fuzzy-set qualitative comparative analysis (fsQCA) to analyze complex causal relationships among variables of question-related characteristics and answer outcomes extracted from the log under the “Artificial Intelligence” topic in ResearchGate. The results show that, when questions contain a high degree of emotion and the questioner is often involved in SQA activities, even if the question text is not highly readable, they will receive high-quality answers; while questions with low answer quantity and quality are often difficult-to-read or from novice academics. In addition, the study proposed a particular pattern of communication in academic SQA: emotion-led communication.

ABSTRACT. Emotional chatbot is a kind of chat robot with the ability of emotional analysis and expression. At present, the technology of emotional chatbot is still in its infancy, and the academia lacks systematic and targeted theoretical re-search on the factors affecting the acceptance willingness of emotional chatbot. Based on the expanded valence the-oretical model, this paper takes users' perceived risk of emotional chatbot services and system quality defects as users' negative potency factors, human interaction, emotional competence and perceived pleasure as positive potency fac-tors, and personal innovation, efficiency expectation and self-efficacy as subjective psychological factors. We discuss the factors affecting users' behavior intentions of emotional chatbot, and takes gender, occupation, education level as adjustment variables to explore the differences of behavior intentions of different user groups for emotional chatbot. The research results provide suggestions for improving and promoting emotional chatbot, and lay a foundation for related research in the academia.

ABSTRACT. Information asymmetry in online consultation is widespread in online health communities (OHCs). As a key quality signal, it is very important to solve the problem of information asymmetry between doctors and patients. Basis on social capital theory, combining the relevant concepts in knowledge management and signal transmission theory to construct a research model, this study aims to explain the deep-seated mechanism of how doctors' popular science works affect patients' online consultation intention. By adopting machine learning and natural language processing technology, a new variable representing "common language" was extracted from the unstructured data of 5927 popular science articles and 43624 online consultation records, and its influence mechanism on online consultation intention was investigated. It is found that the common language of doctors' popular science works has a positive impact on patients' online consultation intention through the mediation of cognitive trust. Moreover, the professional qualifications of doctors can significantly moderate the impact of popular science article trust on patients' willingness to online consultation. The results of this study extend the theoretical connotation and interpretation scope of social capital theory, and provide important reference for doctors to provide popular science knowledge and efficient operation of online medical communities.

ABSTRACT. Service robots are gradually being deployed to replace employees and provide certain services. However, service failures inevitably occur due to technology malfunctions and the nature of service. Appropriate design solutions to increase customer tolerance of service failures are vital for service platforms. Based on the computers as social actors paradigm, voice stereotypes, and social cognition theory, we conducted three scenario-based experiments to explore how the human-like voice types of service robots influenced customer tolerance of service failures. The results indicated that robots with adult female or child voices led to higher levels of customer tolerance than those with adult male voices. Also, warmth perceptions, rather than competence perceptions, fully mediated the effects of robot voice types. Furthermore, for robots with adult male voices, increasing the level of robot intelligence enhanced users’ warmth perceptions and diminished the difference between the warmth perceptions of different voices. These findings contribute to the literature on robot design for customer service and offer implications for practitioners regarding service robot design and deployment.

ABSTRACT. Background With the flourishment of e-health in recent years, e-consultations provided by doctors in Online Healthcare Communities (OHCs) are becoming more and more popular with the public in China. Meanwhile, proactive behaviors of doctors attribute to the success of OHCs, and they are often unsure how to behave proactively to attract patients, with limited research focusing on this. This study aims to explore how proactive behaviors of doctors affect their individual e-consultation service quantity in OHCs. Methods Data in our empirical analysis was collected from one representative OHC in China, referring to 3170 doctors in 865 medical teams. Hierarchical linear regression was conducted to examine the effects of doctors’ proactive behaviors at different levels on individual performance. Herein, proactive behaviors of doctors in OHCs mainly included response speed, pricing and related behaviors in the context of online medical teams. Results This study found that proactive behaviors at different level had significant impacts on individual Service Quantity (SQ) of e-consultations in OHCs. Further, positive effects could be verified in most conditions that were congruent with the logic of common sense, and the interaction terms demonstrated complex influences. Specifically, at the cross level, the switching cost weakened the relationship between price at individual level and individual SQ (β=-0.001, p<0.01), while strengthened the relationship between the response speed (β=0.110, p<0.01) at individual level and individual SQ. At the team level, the response speed in online medical teams positively moderated the effects of both price (β=0.438, p<0.01) and response speed (β=33.678, p<0.01) at individual level on individual SQ. In summary, proactive behaviors at different levels and their interaction effect play key roles in individual SQ. Conclusion Results of empirical analyses enable healthcare providers to adjust their behaviors proactively. In brief, our research provides healthcare practitioners with an improved understanding of the impacts of doctors’ proactive behaviors, and ultimately improve the efficiency and provision of delivered healthcare services in OHCs.

ABSTRACT. 信息市场是一种基于人群的预测工具,人机融合信息市场受益于人和机器互补的预测能力,提供更准确的预测结果。然而,市场中机器的身份披露可能会产生负面影响,机器亲社会行为的设计会减弱这种负面影响。本文研究机器收益分享设计对参与人活跃度(自愿参与预测任务的数量)的影响,具体关注收益分享的两个设计维度:人机交互目标结构(竞争、合作和无特定目标)和分配方式(按绩效分配和平均分配)。其中,前者表示机器的收益在什么条件或情况下分配,后者表示如何做收益分配。本文基于在线实验发现:第一,与人机合作目标结构相比,参与人在人群与机器竞争情境下活跃度更高。第二,引入机器分享收益设计后,参与人的活跃度降低。机器按绩效分配的收益分配方式会增加用户活跃度。第三,在人群与机器竞争的目标下,机器按绩效分配收益时用户活跃度更高。在人群与机器合作的目标场景中,机器平均分配其收益时参与人活跃度更高。除了上述三点关于收益分享设计对活跃度的影响,本文还发现在相对于人机竞争分享,人机合作时的感知机器威胁和感知机器能力更低,而感知机器温暖更高,结合人机合作分享时参与人活跃度低但决策质量高的结果,说明合作的人机交互目标改善了人机竞争交互带来的负面影响,营造了更有效的人机融合预测环境。本文的发现为人机融合预测中机器亲社会行为的设计提供了理论和实践贡献。

ABSTRACT. Deep synthesis can play a positive role in applications such as film production and virtual fitting. It also can generate ethical risks in malicious use such as defamation and fraud. Ethical risks cause public concern, but the concern is not evident in entertaining applications. Therefore, this study aims to understand the role of ethics and entertainment in the acceptance of deep synthesis applications. A mixed-method is used to qualitatively derive the ethical concerns and quantitatively validate the impact mechanism. We confirm that informed consent, privacy protection, traceability, and non-deception have significant impact on ethical acceptability and social acceptance, with privacy protection being the most sensitive. Perceived enjoyment significantly weakens the effect of ethical acceptability on social acceptance. The findings provide the entry point for ethical regulation of deep synthesis applications, and the weakening effect of perceived enjoyment is a wake-up call for regulators to guard against pan-entertainment applications.
ABSTRACT. As urban transportation commuting causes serious pollution problems, green commuting has aroused increased interest in academia. However, there is a lack of understanding of whether or not wealthy residents prefer green commuting and when residents choose green commuting. This study investigates how income (i.e., housing prices) affects residents’ green commuting choices. We integrate a novel data set to generate a unique dependent variable to evaluate residents’ green commuting rate, by combing two large real world transportation data sets. Our empirical analyses indicate a negative relationship between housing prices and green commuting. Additionally, residents’ green commuting choices differ across different commuting purposes. Specifically, the green commuting rate decreases for working, hospital visiting and hedonic purposes. This study contributes to the literature on urban traffic management by using real-world data to examine the factors affecting green commuting, while most of the research in this field is conducted using survey methods.

ABSTRACT. User-friendliness and intuitive interface fostered user participation in online health platforms. People know their health status anytime and anywhere and consult doctors online instead of going to physical hospitals. This study takes an online health platform as the research object, proposes and tests a model to explain users’ continuance intention to participate in online health communities through user engagement and perceived benefit, and tests the moderating effect of perceived vulnerability and perceived severity. The results show that the technology affordance characteristics of online health platforms affect users’ perceived benefit and online engagement, which further influence users’ continuance intention. Perceived vulnerability and perceived severity moderate the relationship between perceived benefits, online engagement and users’ continuance intention. This study has theoretical and practical implications for the online health discipline.

ABSTRACT. Cloud migration is a crucial step in enterprise digitalization. Enterprises migrate applications into the cloud for faster processing time, more access and lower energy consumption than deploying locally. However, the existing works do not consider the efficient utilization of cloud resources when maximizing the enterprises’ utility. In this paper, we propose a cross-layer cloud migration framework for efficiently allocating cloud resources to multiple competing enterprises. We divide the cloud migration system into two layers: enterprise layer and cloud layer. We introduce a Fisher market in economics to obtain optimal service allocation strategy and equilibrium price at the enterprise layer. In the cloud layer, we consider the optimal resource provisioning and formulate the problem as a convex function. Then, we propose a gradient-based algorithm for cross-layer resource allocation. Finally, we verify the effectiveness of the algorithm by simulation.

ABSTRACT. Based on the KMV model to assess credit risk , this paper explores the influence of senior executive changes on enterprise credit risk. On this basis, we can explore the adjustment effect of enterprise incentive mode and governance mode on this influence. The research results found that the credit risk of an enterprise increases significantly after the change of senior management, and the second position of senior management will strengthen the negative effect of senior executive change on the credit risk of enterprises, while the high concentration of equity of enterprises will weaken this negative effect. In addition, the research results found that both salary incentive and equity incentive can weaken the negative effect of senior executive changes on enterprise credit risk.

ABSTRACT. Physicians are the primary providers of online medical services, and their participation is critical to the vitality and sustainability of the online healthcare community. Drawing upon the affordances theory and job demands-resources model, we integrate required online effort and platform affordances in online work settings and propose a dual-path model of online retention for physicians. The expected findings are that physician, cognitive, and emotional labor discourage online retention of physicians, egocentric affordance, online collaboration affordances, and social presence affordances contribute to it, and job crafting mediates these effects. The expected findings may extend the understanding of the theoretical motivation behind continuance behavior and help platform managers to motivate physicians’ continued participation on the platforms.

ABSTRACT. Emerging research reveals the relationship between the Internet and public’s attitude towards healthcare. Some holds that Internet will improve their attitudes while others believe that it will deepen their misperceptions about healthcare. However, there is a lack of research that further disaggregates public attitudes into different dimensions and explores the different impacts of Internet use and Internet involvement. To answer this inconsistency, this study distinguished these two and divided the attitude toward healthcare into three aspects: doctor trust, medical institution satisfaction and medical problem perception. And this study used propensity score matching to analyze the effects of Internet on residents’ attitude by adopting the data from the China Family Panel study in 2018. The results show that Internet use only contributes to the rise of medical problem perception level. And Internet involvement increases Chinese residents’ doctor trust, but also ruined their medical institution satisfaction and exaggerated medical problem perception.

ABSTRACT. In order to fully realize the business value of cloud computing and achieve organizational objectives, it is extremely important to clarify the impact of different environmental characteristics on the ambidextrous innovation value of cloud computing. However, the existing literatures do not fully investigate the moderating role of environmental factors. This study conducts propensity score matching and difference-in-differences-in-differences analysis on the secondary hand performance panel data of 118 pairs of listed companies to investigated the moderating effect of the three environmental characteristics, namely dynamism, munificence and complexity, on the ambidextrous innovation value of cloud computing. The results show that cloud computing significantly promotes exploitative innovation in less dynamic environment and explorative innovation in high complex environments. Nevertheless, munificence explains a less significant proportion of the variance in ambidextrous innovation performance. This research creatively and empirically reveals the realization regularity of cloud computing ambidextrous innovation value under different environmental characteristics which provides theoretical and empirical implications for managers to carry out cloud based operation.
ABSTRACT. With the rapid development of online music platform, music socialization has become one of the mainstream online social forms. For the “effect of people with the same preference gathering together” characteristic of playlist comment section, this study adopts the uses and gratifications theory, technology acceptance model to construct a theoretical framework for the influence of users’ virtual social needs on the playlists’ selection behavior. In Study 1, Python technology was used to capture the playlist comment data. Based on the uses and gratifications approach, and the qualitative analysis method of grounded theory, five dimensions of users’ virtual social needs were obtained, namely, the memory resonance, emotional expression, entertainment, interaction and self-expression needs. Study 2 established an econometric regression model to verify the causal relationship between users’ virtual social needs and playlist selection behavior, using the number of plays, shares, and favorites as the evaluation indicators. The study found that users’ needs for entertainment, self-expression and emotional expression positively influence playlist sharing behavior; while the favoriting and playing behaviors are mainly positively affected by memory resonance and entertainment needs. Study 3 verified the causal mechanism between users’ social needs and the willingness to select playlists by constructing a structural equation model (SEM). Results showed that, different virtual social needs would further influence users’ willingness to play, share, and collect playlists by affecting the perceived usefulness, perceived ease of use, and perceived enjoyment, respectively. The purpose of this study is to reveal the users’ virtual social needs, behavioral patterns and influencing factors of music platforms, and to provide theoretical guidance for the recommendation strategy of high-quality playlists on music platforms.

ABSTRACT. The survival and development of listed enterprises are influenced by financing, and the financing risk assessment of listed enterprises is negatively affected by uncertainties of evaluation information caused by the difference of evaluation experts' experience. To address it, a financing risk assessment method of listed enterprises based on D-number theory improved analytic Hierarchy Process (D-AHP) and approximate ideal solution ranking method (TOPSIS) is proposed. The evaluation index system and hierarchical structure model are established according to the three financing methods of bond financing, equity financing and hybrid financing of listed financing risk. Then the D-AHP is used to solve the impact weight of each index, and the TOPSIS is used to calculate the expert weight. Finally, the financing risk value of listed enterprises is obtained, so as to give reasonable evaluation results about financing risk impact of listed enterprises.

ABSTRACT. Financial fraud has occurred from time to time and disrupts the normal operation of the market and hinders the healthy development of the accounting industry. To address this issue, the US Securities and Exchange Commission (SEC) initiates lawsuits against companies that violate accounting standards and published the records of these lawsuits on Accounting and Auditing Enforcement Releases (AAER). Researchers and practitioner from all kinds of area can then extract different information from it. However, at the moment, most information extraction algorithms depend on large human labor to define rules or mark tags for the training data, which is not feasible for this task. Our study proposes an end-to-end information extraction framework, the context-based one-shot information extraction system (COIES). Our experiment shows that the results of COIES approach human performance which requires only one example with the minimal prior knowledge input.

ABSTRACT. The market performance of mobile apps is very important to developers, but it is difficult to maintain or improve in the highly competitive market. An essential method to achieve the competitive advantage is iterative and incremental to update the apps. We propose a dynamic approach to capture the update strategy of mobile apps. Specifically, Hidden Markov Models are built to examine the relationships among update strategy, user satisfaction, and app performance. Theoretically, we propose that the update strategy determines the transmission between various levels of user satisfaction, which is the hidden states in HMM. Then, the transmission of user satisfaction results in app performance. The critical contribution of our study is that the dynamic process of mobile apps updates is theoretically and empirically examined. In this RIP, we propose the research design and discuss the implications.

ABSTRACT. This study explores the influence of three specific community-based mechanisms on trust and transaction intention from three dimensions of relational governance (relationship norms, conflict resolution and mutual dependence). At the same time, this study compares the differences effect between consumers and prosumers. Taking the second-hand trading platform Xianyu as an example, structural equation model was used to analyze the data based on 721 valid questionnaires. The results show that interest group, feedback mechanism and dispute resolution mechanism all have significant positive effects on seller trust. In addition, the impact of dispute resolution mechanism on trust in seller is higher for prosumers than for consumers. Current research focuses on the impact of social attributes of community on users, this study explores different specific community-based mechanisms.

ABSTRACT. Based on the relevant literature on the elaboration likelihood model and vicarious learning theory, this study investigates the impacts of the danmaku sent by co-viewers on consumers’ purchase intention in E-commerce live streaming. An online experiment was designed and conducted to examine the effects of danmku on consumer behavior in a simulated E-commerce live streaming setting. It is found that the accuracy and consistency of danmaku sent by co-viewers increases consumers’ purchase intention by improving consumers’ vicarious learning. Meanwhile, the credibility of danmaku affects consumers’ purchase intention via eliciting consumers’ resonance. Also, the findings show that age has a moderating effect on the impacts of vicarious learning and resonance on consumers’ purchase intention.

ABSTRACT. With increasing online review manipulation on various transactional platforms, a new merchant manipulation strategy arises – manipulating the reviews by inducing consumers to praise employees’ names in reviews and give high ratings. To explore the effect of this new manipulation strategy on eWOM, this study constructs machine learning models for average rating and rating distribution prediction, using review text related features and name-related feature reflecting the manipulation. Our results indicate that the manipulation of reviews does improve average rating of merchants but leads to sharper J-shaped distribution and low-quality reviews, which will reduce reference value and reliability of reviews, further weakening the positive impact of average rating.
ABSTRACT. 制造业采购经理人指数(Purchasing Managers’ Index ,PMI)是反映国家经济运行情况的重要指标,而传统预测模型对该类时序数据预测精度不高。针对制造业PMI指数的非线性、波动性和数据量少的特点,提出一种基于一维离散小波变换进行数据预处理的组合模型,时序数据经过小波变换,由整合移动平均自回归-广义自回归条件异方差模型(Auto Regressive Moving Average-Generalized Autoregressive Conditional Heteroscedasticity,ARMA-GARCH)处理稳态低频数据,门控循环单元(gated recurrent unit,GRU)处理波动性强的高频数据,将各频段预测结果进行融合得到最终预测结果。为验证模型有效性,选取一定数据量的PMI指数进行实验,结果表明,与其他常见模型对比,本文构建的组合模型具有较好的预测精度与性能,平均绝对误差(MAE)、均方根误差(RMSE)、平均绝对百分比误差(MAPE)分别达到0.00329、0.004162,0.65%。

ABSTRACT. 以往的研究发现美观度可以影响消费者和投资者的选择偏好和价值判断。然而,现有的文献一方面仅关注具体的美学元素(如图片、颜色、字体和图文比例等),缺乏对美观度这一更加全局和抽象概念的衡量;另一方面主要围绕对公司感知形象的影响,缺乏针对公司实际经济利益的定量结论。本文以2007-2019年发布社会责任报告的上市公司为研究对象,首次采用深度学习方法提取社会责任报告中的美观度指标,并考察了社会责任报告美观度与上市公司债务融资成本的经验影响关系。结果发现:上市公司的社会责任报告美观度越高,其债务融资成本越低,意味着更美观的社会责任报告能够更有效地向债权人传递企业履行社会责任和披露信息的积极信号,降低债权人对不确定性的评估,增强债权人对企业还贷的信心。社会责任报告美观度对债务融资成本的抑制作用对分析师关注度高和机构投资者持股比例高的企业更加显著。此外,进一步的分析表明,媒体关注度同样会增强社会责任报告美观度对债务融资成本的抑制作用。本研究不仅从技术增强视角探索了深度学习方法对企业社会责任报告研究的作用,也为公司披露社会责任信息和制作社会责任报告提供了有益的启示。

ABSTRACT. Due to the large amount of inaccurate information online, the public can be particularly vulnerable to misinformation. This study aims to fuse Knowledge Graph and Artificial Neural Network (KGANN) to detect online health misinformation. Our model transforms a public medical knowledge graph into a neural network so that the knowledge graph can be trained by backpropagation algorithm. The model integrates medical knowledge and feature vectors, and determines their weights during training. We performed KGANN on two public disease-specific datasets (including factual and error information related to diabetes and cancer) to validate its effectiveness. The experimental results show that KGANN significantly outperforms two competing methods in terms of F1 Score and Accuracy, and the operation process of the model can be explained to a certain extent through triples in the knowledge graph.
ABSTRACT. 数字平台连接供需两端使得交易在线化,提高市场效率的同时也放大了平台产品的质量与服务问题,平台中的用户投诉数量居高不下。投诉会损害供给端的声誉并可能影响其在平台中的曝光率,进而影响其长期发展,最终不利于平台经济健康发展。因此,本文认为用户投诉会对平台供给端产生影响,包括提高服务水平和增加商品发布数量。基于此,本研究以中国某租房平台为研究情境,关注用户投诉行为,使用双重差分法(DID)检验用户投诉对平台供给端所产生的具体影响。实证结果支持如下结论:(1)用户投诉会导致平台供给端提高服务水平,但不会明显增加房源发布数量;(2)房源相对价格越高,受投诉的平台供给端的服务水平提升越有限,新增房源数越少;(3)所处商圈竞争压力越大,受投诉的平台供给端不会明显提高服务水平,但新增房源数越多。

ABSTRACT. Air pollution is a major issue related to the national economy and the people's livelihood. At present, the research on air pollution emissions mostly focuses on analysis in a specific industry or regions. Enterprise is the most important entity unit of air pollution source. While limited by the amount and granularity of data, there are a few studies on air pollution of industrial enterprises. Especially, there is a lack of research on anomaly of enterprises, the relationships between districts or counties, and between pollutants emitted by enterprises and industries of enterprises. For this purpose, driven by big data of air pollution emissions of enterprises in Beijing-Tianjin-Hebei, the data mining of enterprises’ pollution emissions is carried out, including the outlier detection based on clustering, association rule mining based on Apriori and association degree discovery based on grey association analysis. The results show that: (1) In Beijing-Tianjin-Hebei, industrial enterprises can be divided into six clusters, of which three categories belongs to outliers, which have excessive emissions of total VOCs, PM and NH3 respectively; (2) From the perspective of the association between different data, these districts nearby Hengshui and Shijiazhuang city in Hebei province form strong association rules. (3)From the perspective of the association between different features, the industries affecting NOx and SO2 mainly are electric power, heat production and supply industry, metal smelting and processing industries.

ABSTRACT. Public crisis management is an important part of social governance modernization. The new era has put forward new requirements for social governance. We need to change the concept of governance, build a governance system, and improve the level of governance. The development of fuzzy decision making method further promotes the scientific management of public crisis events. Facing complex and changeable decision making problems in real life, decision makers evaluate and quantify various decisions based on expert index system. They evaluate and rank options through a series of methods to produce scientific and reasonable results. In this paper, we propose a new q-rung orthopair fuzzy number (q-ROFN) ranking method based on the analysis of the existing q-ROFN ranking methods, and apply this new proposal in the TOMID decision making method. The purpose of this paper is to make a selection of public crisis events management scheme by the method of the expanded TODIM decision making.

ABSTRACT. Blockchain has been touted as a game changer in supply chains. While the technology can greatly improve the overall supply chain management, there are ethical challenges, and its ethical nature fundamentally implicates issues associated with sustainable development goals (SDGs). We are therefore yet to know the underlying ethical dilemmas as well as how to navigate the varied ethical complexities while creating value through blockchain-powered supply chains. Using the theoretical lens of normative ethics, this study detects various ethical complexities faced by blockchain in a developing country. The study identifies four types of ethical challenges, and proposes a proper balance between four types of ethical dualisms: balancing design efficiency with ease of use, balancing transparency with privacy, balancing open sharing with adequate data protection, and balancing user concerns with environmental concerns. The study offers rich contextual insights for developing countries and emerging markets, and has both theoretical and practical implications.

ABSTRACT. The pervasiveness of multiple types of digital footprints recorded on e-commerce platforms have added fuel to the design of personalized recommender systems. Despite the abundance, consumers’ digital footprints can be confounded with many causes, both internally and externally. To disentangle the causes driving consumers’ behaviors, a causal recommendation method, i.e., DIPC, based on cause disentanglement at various consumption stages is proposed in the paper. Referring to related theories, interest and item popularity are recognized as causes driving consumer behaviors in the need recognition stage, while behaviors in the pre-purchase and purchase stages are assumed to be motivated by interest and conformity. To rigorously evaluate the performance of DIPC, extensive experiments are conducted on a real-world dataset with carefully designed protocol in terms of modeling multiple digital footprints and causality learning. The results show that DIPC outperforms all baselines significantly and possesses good interpretability, demonstrating the superiority of the proposed causal recommendation method.

ABSTRACT. Social media is used as a front for online mapping of offline public opinion on public health emergencies, and multimodal information with images and texts becomes the main way of public sentiment expression. To make full use of the relevance and complementarity among different modalities and improve the accuracy of multimodal negative sentiment recognition of online public opinion for public health emergencies, we construct a two-stage, hybrid fusion strategy-driven multimodal fine-grained negative sentiment recognition model (THFMFNSR). This model comprises BERT and ViT-based multimodal feature representation, GCN-based feature fusion, multiple classifiers, and rule-based decision fusion. By collecting image-text data about COVID-19 from Sina Weibo, this paper verifies the effectiveness of the model and extracts the best sentiment decision fusion rules and classifier configurations. The results show that compared with the optimal sentiment recognition model with text, image, and image-text feature fusion, the accuracy of this model in sentiment recognition and fine-grained negative sentiment recognition is improved.

ABSTRACT. We examine the effect of social capital on participant retention in online mental health community, and disentangle the effect of bridging and bonding social capital on participant retention in this paper. Specifically, we derive participant profile data and activity data for 15 years from a Chinese online mental health community and construct social networks based on reply relationship for every half year. Following prior studies, bridging social capital and bonding social capital are measured by structural holes and network closure respectively. We conduct survival analysis to examine whether social capital has effect on participant retention, and use panel Logit model to capture the efficacy of different types of social capital. Results show that social capital significantly improves participant retention rate; bridging social capital has positive effect on participant retention, whereas bonding social capital has negative effect on participant retention

ABSTRACT. Though online retailers have put much efforts to optimize product image to attract consumers and increase revenue, studies about how specific image features promote product sales are rare. This study aims to examine whether image features have impact on product sales, and identify a set of key features essential to promote product sales. Specifically, we collected product images and corresponding sales data from one of the leading online food delivery platform in China. We used image processing technology to obtain image global features and regional features, and conducted a cross-sectional analysis and a difference-in-difference-in-differences framework to examine the effect of image features on sales. Results show that image saturation, colorfulness and the difference of contrast between foreground and background positively influence product sales, while image contrast has negative effect on sales. This study sheds light on the effect of image features and provides practical implications for product presentation

ABSTRACT. Although AI-based chatbots have burgeoned in multiple business practices and demonstrated emerging potential in emotional support, little knowledge about the mechanism underlying the relationship between AI-based relational chatbots’ anthropomorphic attributes and user engagement. Drawing from the social judgment theory, we integrated agentic-style and communal-style to build relational chatbots’ conversational styles and proposed that emotional judgement mediated the relationship between conversational styles and user engagement with relational chatbots. Two types of AI avatars (humanlike vs. cartoonlike) are employed to examine the possible boundary effect of the above relationship. Two studies involving several online and lab experiments are planned to conduct to examine our hypotheses further. It is expected that we could extend the existing theories involving social judgment theory and human reactivity to AI-based chatbots in the setting of emotional care, and identify the potential joint effects of different types of anthropomorphic attributes of AI-based relational chatbots on user behaviors.

ABSTRACT. We aim to explore how listings owned by a multi-listing host affect each other, and the spillover effects of other listings’ online reviews on focal listing. Using a unique dataset of 1478 listings managed by 542 hosts ranging from October 2012 to June 2019 on Xiaozhu.com, we constructed two empirical models to examine the main effect of the number of other listings owned by the same host and the moderating effect of other listings’ online review on the focal listing performance, i.e., date difference between listing’s first sales and online date, and listing’s monthly sales. The results show that the number of other listings owned by the same host negatively affects listing performances, and online reviews have positive spillover effects. Our research contributes to both the home-sharing and spillover effect of online review literature and has substantial implications for the operators of home-sharing platform and multi-listing hosts on the platform.

ABSTRACT. After service failure, the occurrence of chatbots often brings bad service experiences to people. In order to improve consumer satisfaction when interacting with chatbots in service recovery, we design an online experiment to explore appropriate communication style designs for chatbots, also considering the moderating effects of consumers’ relationship orientation and task complexity. Results show that during service recovery, consumers are more satisfied with social-oriented chatbots rather than task-oriented ones. Besides, we explore the mechanism by which the communication style affects consumer satisfaction in service recovery by introducing cognition-based trust and affect-based trust as mediating variables.

ABSTRACT. 对消费者购买行为及其内在机理展开深入研究,能帮助企业及营销人员更有效的了解消费者需求,实施营销计划,完成企业目标,实现企业愿景。目前关于在线视频广告的广告效果研究,许多学者将目光聚焦于广告和视频的相关度,包括广告产品和视频主题的相关度,广告类型和视频类型的相关度,广告音乐和视频音乐的相关度等。研究发现,广告相关度对消费者的品牌态度和购买意愿会产生积极影响。但大多数都是采用传统测度的行为学实验进行研究的,也就意味着它无法揭示消费者在观看不同相关度的广告时,大脑对广告信息的认知加工过程。本文探讨在线视频广告在内容方面的相关度对消费者品牌态度的影响,以及他们如何受到情绪、加工流畅性和说服知识的影响。通过结合使用功能性磁共振成像技术和问卷调研法,本文得出以下结论: (1)广告-视频的内容相关性会影响消费者对广告中出现商品的品牌态度。相关性程度越高,品牌态度越好; (2)广告-视频的内容相关性会影响消费者对广告的情绪,进而影响对广告中出现商品的品牌态度。相关性程度越高,情绪越积极,品牌态度越好; (3)广告-视频的内容相关性会影响消费者对广告信息的加工程度,进而影响对广告中出现商品的品牌态度。相关性程度越高,信息加工流畅性越好,品牌态度越好; (4)广告-视频的内容相关性会影响消费者大脑杏仁核和纹状体ALFF的激活。相关性程度越高,激活越强烈。 (5)加工流畅性和杏仁核激活情况存在显著正相关关系,加工流畅性越高,杏仁核激活强度越大。 (6)随着视频播放,消费者进入视频情境,杏仁核ALFF激活程度逐步降低。 本研究在理论层面,不仅从管理学角度解释视频-广告的内容相关度为什么会影响消费者的品牌态度和购买意愿;而且从神经角度探寻广告相关度对消费者购买意愿影响背后的神经机制,丰富国内学者对在线视频广告效果的研究。最后,在现实层面,可以给企业的广告的内容制作和投放策略提供理论支撑和建议。

ABSTRACT. Video has become an emerging carrier of user-generated content (UGC). As a branch of self-media videos, product review videos posted by influencers have become an influential channel in shaping consumers’ purchase decisions. In the past, studies on influencer marketing have largely focused on textual and pictorial social media posts, while there was a lack of research on unstructured UGC videos, from which we can extract deep cognitive and affective information. In this paper, we constructed a theoretical model to explain the influence of product review videos on viewers' attitudes based on the cognitive-affective framework and authenticity theory. Specifically, we posit that viewers’ attitudes towards the product and the influencer will be influenced by both cognitive cues (i.e., information amount and topic diversity) and affective cues (i.e., vocal and facial emotional intensity) because these cues will affect perceived authenticity on influencers. In addition, such effects will differ across different types of videos (i.e., shopping-haul videos and anti-haul videos). A mixed-method approach was proposed to test the theoretical model. In Study 1, we collected product review videos from Bilibili.com, used text mining, sentiment analytics, audio analytics, and facial expression analytics tools to extract video features, and conducted regression analyses on viewers' attitudes (i.e., viewers' sentiment towards the product and the influencer). We further proposed a lab experiment to establish causality between video features and viewer attitudes, and to elucidate the mediating role of influencer authenticity. The contribution and implication of the research are discussed.

ABSTRACT. The liberalization of trade and globalization bring challenges as well as opportunities to companies, especially for the Small and Medium Enterprises (SMEs). In order to reduce time and costs, while increasing the quality of products, an efficient implementation of systems engineering process is necessary. However, even if a few systems engineering standards especially address SMEs, surveys show that SMEs hardly use formalized processes, resulting in poor process reproducibility and monitoring, among other drawbacks. Indeed, because of strong resource limitation, SMEs have difficulty to estimate any short-term benefit in spending time formalizing their processes. Against this background, this paper explores a methodology to support project managers in fostering the progressive deployment and standardization of engineering processes in SMEs starting from the perspective of their own experience and referring to the international systems engineering standards. Our proposal stands by the companies’ side to help companies to make their engineering processes evolve by progressively aligning them with the systems engineering standards without disrupting the entire organization and practices of the company.
ABSTRACT. Recently, short-video platforms have become popular among the middle-aged and elderly. While some studies proposed that excessive use of short-video platforms may lead to many psychological problems, little knowledge is about how to help the middle-aged and elderly use platforms reasonably and gain subjective well-being. Drawing on generativity theory and social cognitive theory, this study demonstrated that middle-aged and elderly users who have a higher level of need to be needed would achieve a higher level of subjective well-being and build more social interaction on short-video platforms. Especially, through building more social interaction on short-video platforms they can achieve a higher level of online subjective well-being. Moreover, when middle-aged and elderly users received more family cognitive support, the positive relationships of need to be needed with subjective well-being and social interaction on short-video platforms would be stronger, however, the positive relationship between social interaction and subjective well-being would be weaker.
ABSTRACT. AI technology empowers AI agents to recognize and convey emotion and social cues, creating frequent interaction between consumers and AI agents, and an emerging human-AI relationship emerges. To advance our understanding of this human-AI relationship, this study proposes that perceiving a mental state is positively associated with the human-AI relationship and investigates the underlying mechanisms. Specifically, a survey was conducted to test the hypotheses. The results show that two dimensions of empathy are positively associated with harmonious human-AI relationships through elevated perceived anthropomorphism and psychological empowerment. Furthermore, this study verified interaction effects, comparative effects, and service stages differences. Finally, theoretical contributions and practical implications are discussed.
ABSTRACT. In live-streaming e-commerce shows, the reputation of influencers plays a central role because it affects the brand-side price negotiation and the consumer-side long-run profitability simultaneously. Building on the career concern literature, this paper examines the effect of the influencer's reputation on price negotiation. Our analytical and numerical results suggest that the price obtained from the negotiation is affected by the reputation concern non-monotonically. An influencer with a greater reputation concern may get a smaller discount. Besides, the brand, the influencer, and consumers are better off simultaneously if the influencer has a moderate career concern.
ABSTRACT. A substantial body of platforms literature has primarily characterized two-sided platforms as markets with cross-side network effects (CNEs). Most literature investigates how to attract more suppliers to leverage CNEs but ignores that CNEs driven by different suppliers may be heterogenous. To fill this gap, we identify two distinct suppliers i.e., individual hosts and professional hosts with three key differences in a set of housing rental platforms and examine how CNEs are influenced by different suppliers. Our results suggest that the quantity of individual hosts (vs. professional hosts) has larger CNEs on the renter size. In turn, renter size has larger CNEs on the quantity of individual hosts (vs. professional hosts), while renter size has weaker CNEs on the quality of individual hosts (vs. professional hosts). These findings generate important implications regarding how two-sided platforms may better govern ecosystems with different participants.

For the banking industry, credit card business is an important part of its personal loan business, and it is crucial to forecast the default probability of cardholders. A robust predictive model is not only a useful tool for banks to make judg-ments at the time of credit card application, but will also help customers to realize that this is an action that may harm their credit score, thus achieving the effect of default prevention beforehand.With the continuous enrichment of cardholder information, traditional statistical tools can no longer meet the prediction needs, and machine learn-ing methods suitable for big data analysis have started to be applied in the field of credit card default prediction. Among them, the Gradient Boost Decision Tree (GBDT) algorithm has emerged with various improvements based on GBDT, including XGBoost, LightGBM and CatBoost, because it can achieve better results in different scenarios. Among them, CatBoost is the improved version of GBDT with better comprehensive effect. Based on CatBoost al-gorithm is widely used in e-commerce, disease prediction and other fields, this paper uses CatBoost algorithm to predict credit card default probability.In this paper, the cardholder information of American Express credit card during 2017 is selected as the dataset, the variables are made easy to read by changing the data format, exploratory analysis is performed on 190 variables, various visualizations are tried, the categorical variables among them are selected, and Catboost is used to train the classifier and make predictions, and good accuracy is achieved.

ABSTRACT. Artificial intelligence system is more and more widely used in enterprises. The research on the application effect of artificial intelligence system is of great significance. Taking safe driving as a scenario, this paper investigates the influencing factors of effective use (improving drivers' safe driving behavior) of intelligent safe driving assistance system in enterprises. Based on the theory of person-environment fit, this paper proposes a research model on how individual factors (i.e., age) and organizational factors (i.e., safety assessment system and workload) affect the effectiveness of the system. Further, we analyzed and verified the research model with the driving behavior data from a large petrochemical enterprise for 4 years. The results show that the intelligent safe driving assistance system is more effective for older drivers. When the enterprise is equipped with the corresponding safety assessment system or the workload is low, the safe driving assistance system will be more effective. At the same time, there are also significant interactions among the above factors. When the workload is large, the safety assessment system plays a greater role. The positive effect of safety assessment system on the effectiveness of intelligent monitoring system is more obvious among older drivers. The negative effect of workload on the effectiveness of intelligent monitoring system is more obvious among young drivers.

ABSTRACT. Recent studies show that, when choosing between risky alternatives, people do not only integrate values and probabilities for each gamble but also use component comparison procedures to compare relative values and probabilities across gambles. This suggests that the salience of the gamble and emotional arousal may play an important role in risky decision-making. This study explores the effect of attention, pupil-linked arousal, and salience on the risky decision-making processes. We find that when the expected utility calculation is easy, people do the calculation, however, when the expected utility calculation becomes harder, they compare payoffs and are attracted to the salient option. Further, we find that pupil-linked arousal reflects the cognitive effort involved in the calculation of the expected utility and the cognitive effort employed to conquer the attractiveness of the more salient option.

ABSTRACT. Many organizations have adopted enterprise social media to improve employees' job performance. It has become common for employees to use enterprise social media to deal with work during non-working time. However, the impact of non-working time enterprise social media use remains unclear. Based on conservation of resource theory, this paper constructs a research model to study the relationship between enterprise social media and job performance at different times. Using structural equation model to analyze 323 employee’s data, the results show that: (1) Neither working nor non- working time enterprise social media use has significant effect on emotional exhaustion. (2) Both working time and non-working time enterprise social media use have promoting effect on organizational commitment. (3) Emotional exhaustion has inhibited effect on job performance, and organizational commitment has promoting effect on job performance. Finally, the theoretical and practical implications of this study are explored.
ABSTRACT. Content creators, such as YouTube and TikTok influencers, attract growing attention from advertisers, which presents a novel tradeoff for the hosting platform. On one hand, allowing content creators to embed sponsored ads (CADS) in the content undermines the platform's own ad sales (PADS); On the other hand, the platform might benefit from CADS through commissions. We develop a game-theoretical model to examine this tradeoff, in which a group of content creators and their hosting platform compete with each other on ad sales. We find that the dual mode (i.e., allowing CADS) might be optimal for the platform, depending on the qualities of PADS and CADS. Unlike the literature where the relationship between the platform offerings and the third-party participation is exogenous, we show that the strategic relationship between PADS and CADS can be substitutable, complementary, or independent from each other, which is endogenously determined by the platform.

ABSTRACT. Multimodality is one of the important directions of AI-powered learning at present and in the future. Improving crystallized intelligence is one of the goals of AI-powered learning. In this study, we develop a theoretical model to explain the relationship between modality of AI and crystallized intelligence, based on the Biggs 3P model. We test the hypotheses using data from an experiment (N = 324) and found that modality of AI has a positive effect on deep learning approach and a negative effect on surface learning approach. The modality of AI can affect crystallized intelligence both directly and indirectly through deep learning approach. Moreover, we examine the moderating effect of technological readiness from learners’ perspectives. Optimism and insecurity have moderating effect on the relationship between modality of AI and two kinds of learning approaches respectively.

ABSTRACT. The rapid growth of virtual reality (VR) technologies and computing power has given birth to immersive platforms, where users can immerse in a 3D virtual world and engage in various activities such as job training, remote collaboration, and innovative marketing practices. Through the lens of self-perception theory, this paper investigates how avatar design, i.e., user-avatar similarity, affects users’ self-concepts and shapes their behaviors in immersive VR. The preliminary experiment reveals that higher avatar-user similarity leads to higher task engagement in general. Furthermore, while a similar avatar promotes users to regulate their behaviors and achieve better performance in a procedural task, high similarity also inhibits users’ creativity by invoking habitual thinking, resulting in worse performance in generating original ideas in a creative task. This study is expected to contribute to HCI literature by revealing the value of avatar design and providing new perspectives in improving users’ experience in the immersive virtual world.

ABSTRACT. The textual risk disclosures in financial reports, which discuss the company’s potential risks from a forward-looking perspective, were rarely considered in financial distress prediction. Thus, this study explores whether the textual risk disclosure of financial reports can help predict the financial distress or not. To comprehensively extract information from the massive unstructured textual risk disclosures, the textual attributes are utilized to capture the linguistic styles of risk disclosures and an unsupervised topic model is adopted to identify the textual topics (the content of the text) in risk disclosures. Based on the textual risk disclosures of 4,039 financial reports for U.S. energy companies from 2006 to 2020, the empirical results demonstrate that the textual attributes and textual topics extracted from risk disclosures in financial reports can significantly improve the financial distress prediction performance compared with commonly used numerical variables (financial and market variables). Moreover, the textual topics in risk disclosures can provide more information than commonly used textual attributes for financial distress prediction. Last but most importantly, the textual risk disclosures become more and more useful relative to numerical variables as the predicting time horizon becomes longer. This study can help investors and regulators understand how to analyze the textual risk disclosures in financial reports and incorporate the textual information into financial distress prediction.

ABSTRACT. 数字政府建设以来,政务界面渐成公众获取公共服务主要渠道,但政务界面的公共服务供给特征如何影响公众的感知绩效尚未明晰。本文从界面治理理论视角切入,结合感性工学理论,采用交叉学科方法分析28个省级微信政务小程序界面。研究发现,服务形象、服务供给和服务创新是影响政务界面公共服务感知绩效三个维度;服务形象和服务供给分别受政务界面“外观形态要素”与“功能形态要素”两类供给特征影响,服务创新则是受界面整体影响;地域风景版面较小、证照卡包按需添加、专题服务列表导航且设置标题列举服务、小标题长度适中、整体字体适中、不设置其他信息区、设置底部导航区可以提升服务形象和服务供给维度的公共服务感知绩效。本文加深了学界对政务界面的理解,深化了界面治理理论内涵,并提出政府应当构建清爽、弹性、人文的政务界面。
ABSTRACT. 本文选取中国大陆31个省级行政区的数据构建关系矩阵,利用UCINET软件进行网络图谱、中心性、块模型、差异性和相关性分析,借助二次指派程序分析地域及疫情的调节作用。研究发现区域民间借贷风险网络存在风险中心,网络结构和位置特征均影响借贷风险传导。P2P平台表现出更明显的集聚效应,和实体借贷协同加剧民间借贷风险传导。东部省级行政区位于更核心的位置,疫情的调节作用不明显。相关部门应提前防范借贷风险,以进行公共危机管理。 We selected the data of 31 provincial-level administrative regions in mainland China to construct a relationship matrix, analyzed the network map, centrality, block model, difference and correlation by UCINET. Through the quadratic assignment procedure, we verified the moderating effects of regions and the COVID-19. Major findings include that there are risk centers in the regional private lending risk network and the network structure characteristics affect the transmission of lending risk; P2P (Peer-to-Peer) platforms show a more obvious agglomeration effect, and synergize with physical lending to exacerbate private lending risk transmission; the eastern provincial administrative regions are located in a more central position, and the moderating effect of the COVID-19 is not obvious. Relevant departments should prevent private lending risks in advance for public crisis management.
ABSTRACT. 正式借贷与非正式借贷渠道并存的二元结构是中国信用市场的主要特征。研究采用中国家庭追踪调查(CFPS)2014—2018年三期面板数据,选取Probit模型实证探究中国农村家庭的借贷渠道决策中是否存在同伴效应。研究发现:同伴效应对农村家庭借贷渠道选择有显著的正向影响,但通过外部渠道获取的信息会削弱这种影响。此外,针对家庭特征异质性,同伴效应的作用程度存在差异。在考虑遗漏变量、因果识别和渠道干扰问题后,研究结论保持稳健。

ABSTRACT. Understanding how government short videos promote citizens’ policy compliance in times of epidemic outbreaks is worthy of attention. Based on grounded theory, this study constructs a theoretical model of government short videos influencing policy compliance taking China's interview data as evidence. Results show that government short videos have significant effects on citizens’ policy compliance through four cognitive appraisals: epidemic, policy, government-public relationship, and social influence. In addition, resilience as an individual feature moderate the relationship between these cognitive appraisals and compliance. Findings contribute to the study of COVID-19 policy compliance and enrich the literature on policy compliance antecedents from the perspective of information sources and cognitive appraisals.

ABSTRACT. 如何优化在线有奖推介活动设计以获取更多新用户是商家和学者关注的重要话题。实践中,许多推介活动中出现了积分等媒介型奖励,然而这种新兴设计对用户感知与决策的影响仍知之甚少。基于动机理论和媒介相关研究提出,媒介型奖励会改变用户的社交动机和外在动机,对推介意愿的影响与其和推介对象的社交关系强度密切相关。三个实验的结果表明,当向弱关系发起推介时,媒介型奖励则会降低用户的感知社会风险,进而提升其参与意愿;当向强关系发起推介时,媒介型奖励会降低用户的感知推介价值,进而降低其参与意愿。研究结论有助于拓展对有奖推介活动、媒介研究和动机理论等多方面的认识,对于商家优化在线有奖推介活动设计具有指导意义。
ABSTRACT. 本文结合TOE框架,采用模糊集定性比较分析方法,从组态视角揭示提升企业数字化转型的关键路径。主要研究发现是:单一因素无法构成高水平数字化转型的必要条件,高水平企业数字化转型是多重技术、组织、环境因素共同作用的结果;具体地,四条不同的组态路径能实现高水平数字化转型,它们均是技术、组织、环境三方面因素的不同组合,而且,信息技术基础设施和CEO教育是关键的核心要素和辅助要素,行业竞争和研发投入之间存在匹配效应。

ABSTRACT. The referral reward program (RRP) is a social marketing method by which firms reward existing users and encourage them to recommend products or services to their friends. Prior research has primarily focused on the impact of RRP design on users’ participation, however, the role of individuals’ characteristics is unexplored. Based on regulatory focus theory and self-efficacy theory, this research proposes and investigates the effect of users’ regulatory focus (promotion-focused vs. prevention-focused) on their referral intention and explores its mechanism and boundary condition. The results of three experiments show that compared to the prevention-focused user, the promotion-focused user has higher self-efficacy to complete the referral task; and thus, has higher referral intention. This effect will be attenuated when the tie strength between inviter and invitee is strong. The findings not only contribute to the research on RRP and regulatory focus but also can provide guidance for firms to optimize their RRPs.
ABSTRACT. 针对区域间优质医疗资源分布不均,区域医疗服务质量可能存在较大差异的特点,进行不同地区医疗服务质量影响因素差异分析具有重要的意义。为了探究我国不同经济水平地区医疗服务质量影响因素存在的差异,以经济水平较为悬殊的北京地区和西部地区的三甲医院为研究对象,基于患者的在线医疗评论,利用改进的BTM主题模型进行评论挖掘,基于主题挖掘结果和SERVQUAL模型进行三甲医院医疗服务质量影响因素识别。利用调查问卷和因子分析法修正并建立医疗服务质量影响因素指标体系,利用相似度算法计算两地区患者对各因素的关注度,从区域层次出发,利用卡方检验等统计分析方法,详细对比北京地区和西部地区三甲医院患者对医疗服务质量影响因素的关注度、好评率和服务满意度,并针对北京地区和西部地区医疗服务质量影响因素的差异提出相关建议,为政府部门合理调配医疗资源、出台相关政策、医疗机构提升医疗服务质量提供支持和帮助。
