中国城市科技人才集聚促进了全要素生产率增长吗——来自285个地级市的经验研究

基于2005—2018年中国内地285个地级市数据，对城市科技人才集聚与全要素生产率（简称“TFP”）进行测度分析，实证考察科技人才集聚对TFP的影响。结果表明：①城市科技人才集聚与TFP空间分异特征显著，但二者具有较强的时空一致性，即科技人才集聚特征显著的城市，其TFP也相对稳定；②城市科技人才集聚对TFP的影响呈倒U型，但研究期内大多数城市仍处于集聚效应占主导阶段,科技人才集聚通过提升城市技术进步水平促进TFP增长，而科技人才集聚对技术效率的影响呈倒U型；③不同类型城市科技人才集聚对其TFP影响的异质性显著，且适宜集聚区间也存在差异。省会城市及一、二线城市等优势特征显著的城市所能承受的科技人才集聚规模上限更高，有利于通过释放集聚红利促进TFP增长，而非省会城市、三线及以下城市等则拐点值较低。     

The social process of internet appropriation: Living in a digitally advanced country benefits less well-educated Europeans

We generalize and extend the sequential model proposed by the resources and appropriation theory to explain the digital divide in the European Union plus the United Kingdom (EU27+UK). We measure the theoretical constructs of the model with data provided by the EU and test the theoretical predictions using a partial least squares structural equation model. We find support for the hypothesized relationships but find that the effects vary depending on the digital development level of countries. While education overall is the primary determinant of the social production of digital inequalities, a country's digital development level is crucial for less well-educated Europeans. These findings have theoretical and practical implications: (1) they call into question the homogeneity of the effect of causal relationships and the assumption that individuals differ only in terms of motivation, access, and digital skills, and (2) they indicate that socially disadvantaged Europeans benefit from living in more digitally developed countries.     

“I live with terror inside me”: Exploring customers’ instinctive reactions to terror

Terrorist attacks occur mostly at public service-oriented sites. Consequently, their victims are likely to be customers. The present study explores how customers instinctively react toward the reality of terror in a matrix of 2 × 2 aspects concerning terror circumstances: temporal proximity (brief or long) and physical proximity (close or remote) from the terror event. In qualitative in-depth interviews, customers from France and Israel were requested to share their instinctive reactions and coping strategies when approaching hospitality (hedonistic) and transportation (utilitarian) services. Participants (N = 47) comprised customers having a protracted acquaintance with persistent terror threats. The analysis identified differences in reactions, subject to temporal and physical proximities. When terror attacks are physically close, customers’ emotions, cognitions, and behaviors undergo modification with time. However, when terror attacks occur at a location remote from the customer, customers’ emotions and cognitions, but not their behavior, change with time. These reactions were comparable for the two service contexts. Practical implications were elaborated to enable service establishments (i.e., hospitality and transportation) to design and manage their operations for the short and long term to assist customers in the difficult era of terror.     

美貌能带来幸福感吗?

作为一项稀缺资源，好的外表能够为个体带来多重溢价和福利。文章基于中国家庭追踪调查（CFPS）数据考察了个体的外貌与主观幸福感之间的关系。研究发现，在控制了影响幸福感的其他因素之后，个体的外貌对其幸福感依然有着显著的正向影响：外貌更具吸引力的个体，其自评的生活满意度更高。外貌的这一影响在不同性别、不同年龄段和不同收入群组中均有所差异。同时，在该影响机制中，个体的经济状况扮演着中介渠道的角色。文章运用访员固定效应和工具变量估计控制了模型的内生性问题。     

Conceptualization of e-servicescapes in the fitness applications and wearable devices context: Multi-dimensions,consumer satisfaction,and behavioral intention

Based on the environmental psychology theory, this research conceptualizes and investigates the dimensions of e-servicescapes, and examines how each dimension influences fitness application and wearable device users’ emotions, satisfaction, and behavioral intention to continuously work out via the technology. This study employed three waves of surveys within the United States to collect data (N = 343), and conducted a path analysis to rigorously assess the proposed paths between identified constructs. The empirical findings revealed the significant determinants of negative emotion (i.e., usability, security, customization, entertainment value, interactivity, originality of design, relevance of information, and social factors) and positive emotion (i.e., usability, customization, entertainment value, interactivity, and relevance of information). Also, satisfaction was significantly impacted by both positive emotion and negative emotion, and behavioral intention was significantly influenced by positive emotion and satisfaction. Based on these findings, this study suggests theoretical (i.e., classification of the e-servicescape dimensionality and integration of the environmental psychology theory with the two-factor theory of motivation, focusing on a digital environment) and practical implications (i.e., ways to increase levels of consumer satisfaction with the technology and intention to continuously exercise with the technology) for scholars and practitioners in the fitness and mobile application/wearable device industries.     

Bridging the valuescape with digital technology: A mixed methods study on customers’ value creation process in the physical retail space

This mixed methods study investigated how value is created in the physical retail space and how the customer experience is influenced by digital technology. A cross-sectional survey, with both qualitative and quantitative components, was distributed across a heterogeneous sample of 832 customers. The results revealed an overarching model comprised of three interrelated clusters: customer, service provider, and digital technology. We propose that this model can be understood as a valuescape, where customers' specific goals, needs, and desires drive them to interact and co-create value with service providers in the physical retail space, with digital technology either enhancing or disrupting this value co-creation process. The results also show that the importance of aligning digital solutions with customers’ drives increases at the same pace as reliance on technology. The findings offer guidelines on how to utilize digitalization to leverage customer experiences and thus strengthen the attractiveness of physical retail spaces.

经济政策不确定性与企业投资趋同行为

文章以2003-2017年A股非金融类上市公司为研究样本,考察经济政策不确定性对企业投资趋同行为的影响。研究发现,经济政策不确定性的升高会显著增强企业投资趋同行为,该影响效应在信息优势企业有所减弱,在资产不可逆程度较高企业有所增强。分行业检验发现,在管制性行业以及景气度较低行业中,经济政策不确定性对企业投资趋同行为的影响减弱。进一步研究发现,在经济政策不确定性不断攀升的背景下,实体投资趋同性会带来更为严重的金融化,特别是在行业实体投资总体趋于放缓的情况下,企业金融化现象更加严重。该研究为宏观经济波动下企业投资趋同行为提供了经验证据。
