问题导向：科研功能视角下文献综述的进阶设计

与人们从事的其它工作一样，科学研究者所做的文献综述也是一个积累经验与循序渐进的过程。现有研究尚未系统地探讨有关文献综述者“进阶”问题，大多数研究者都关注文献综述了解现状而非解决问题的功能。通过较为全面系统的文献收集与整理分析，根据研究思路与研究方式划分得到现有研究存在4种文献综述类型，基于科学研究层次划分得到文献综述4种功能。在此基础上，将文献综述置于整个科学研究框架下，基于科学研究最为根本与最有价值的问题解决功能及执行过程，提出初级文献综述者向高级文献综述者转变的“进阶”路径及具体操作步骤，包括聚焦研究问题而非研究现状、精心设计而非简要构思、做实做全文献综述而非目标框定、做精做深结果呈现而非简要罗列叙述及具体实施举措。     

The China–US Trade War: Deep‐Rooted Causes,Shifting Focus and Uncertain Prospects

The USA has waged a trade war against China, whose rapid rise has come to be seen as a threat to US hegemony. Besides imposing additional tariffs on imported Chinese products, the USA is also tightening restrictions on the transfer of technology to China and the business activities of some Chinese high‐tech companies, notably Huawei. The escalation of the trade war into a tech war could lead to a decoupling between the US and Chinese economies, if not a world economy divided into two economic blocs that centered on them.     

中国价值工程研究40年的回顾和展望

中国价值工程研究可以分为三个阶段:引进和消化期(20世纪70年代末至1987年)、研究和应用的活跃发展期(1988年至20世纪90年代中前期)以及平稳发展期(20世纪90年代中期至今)。价值工程在中国的发展历程是中国改革开放进步的写照,行政支持是发展的重要推动力,而价值工程应用则带动了价值工程研究发展。理论创新主要集中在拓展价值工程研究领域,以及完善和改进价值工程分析方法。展望未来,需要进一步加强价值工程理论研究,引进和采用新的研究分析方法,以及加强专业教育和专业组织建设。     

Enabling supply chain analytics for enterprise information systems: a topic modelling literature review and future research agenda

ABSTRACT

This paper provides a literature review of the research within the framework of 1) analytics,2) supply chain management, and 3) enterprise information systems, and relate the findings to competitive enablers. The findings are used to construct a future research agenda. The methodology is a systematic two-stage approach, based on a Smart Literature review framework using topic modelling. The research agenda proposes future research within the themes of 1) context, 2) cross-functional analytics, 3) cross-planning level analytics, 4) implementation and assimilation of analytics in EIS, 5) analytics and big data for SCM, 6) managerial aspects of analytics, and 7) data and system heterogeneity.     

Online persuasion of review emotional intensity: A text mining analysis of restaurant reviews

Consumer-generated restaurant reviews are important sources in consumers’ purchase decisions. The purpose of this study is to explore the impact of emotional intensity on perceived review usefulness as well as the moderating effects of review length and reviewer expertise. Data from 600,686 reviews of 300 popular restaurants in the US were obtained from Yelp. Using a text mining approach and econometric analysis, empirical results show that (1) positive emotional intensity has a negative impact on perceived review usefulness, whereas negative emotional intensity has a positive impact on perceived review usefulness; (2) among the two most prevalent discrete negative emotions in online reviews (i.e., anger and anxiety), reviews expressing anger are more useful than those expressing anxiety; and (3) review length and reviewer expertise can moderate the effect of emotional intensity on perceived review usefulness.     

EQUITY HOME BIAS: A REVIEW ESSAY

This paper reviews the relatively more recent literature on equity home bias – the empirical finding that people overinvest in domestic stocks relative to the optimal investment portfolio implied by the modern portfolio theory. It reviews six broad classes of explanation of this puzzling phenomenon: (1) hedging home risks; (2) barriers to foreign investments; (3) information asymmetries; and (4) behavioral factors. The consensus is that none of the explanations can account for the full extent of the bias by itself, thus the home bias should be explained by a combination of rational and behavioral factors.

The effect of online reviews on hotel booking intention: The role of reader-reviewer similarity

Due to the experiential nature of travel-related products, online reviews have become an increasingly popular information source in travel planning and have a profound effect on consumers’ buying decisions, particularly in hotel booking. On the basis of homophily and similarity-attraction theory, we posit that review valence is positively related to consumers’ hotel booking intentions, and expect this relationship to be moderated by surface- (demographic) and deep-level (preference) similarities. The findings from two experiments conducted in Germany and Macau indicate that review valence significantly affects hotel booking intention, and that reader-reviewer demographic similarity moderates this effect. This three-way interaction reveals a substituting moderation effect between demographic similarity and preference similarity. One practical implication is that travel websites should find methods of exposing users to reviews written by those with either similar demographic characteristics or preferences, which facilitate travelers’ decision-making processes.
