我国金融“脱实向虚”的综合判断与分析*

本文界定了金融“脱实向虚”的内涵，设计了研判金融“脱实向虚”的挂钩变量和标准。本文以1990—2019年78个国家为样本的实证研究显示：2012年我国金融出现“脱实向虚”，2012—2014年处于低度“脱实向虚”状态，2015—2018年出现了中度“脱实向虚”，2019年又回落到低度“脱实向虚”，但未来5年金融杠杆会回升。这意味着未来经济运行仍将面临高杠杆带来的系统性金融风险，以及金融杠杆波动性不断加剧给经济增长带来更大的负面冲击。宏观调控的政策取向和首要任务仍是“降杠杆”和“稳增长”。针对该形势，本文提出：一是亟须建立金融“脱实向虚”的审慎监管机制，将金融杠杆作为金融“脱实向虚”的审慎监管政策工具，将均衡金融杠杆作为研判金融“脱实向虚”的标准，前瞻性地引导金融回归服务实体经济的本位职能。二是改革现有存款基准利率的“双轨制”，实施货币政策“锁短放长”的创新性操作来消除导致金融“脱实向虚”的政策诱因。     

Sensory Aspects of Retailing: Theoretical and Practical Implications

Sensory elements are an important aspect of both offline and online retail stores and can non-consciously influence consumer judgments and purchase behavior. In offline settings, ambient factors like scent, lighting, and music have been shown to influence customers’ shopping experiences and their buying behaviors. For online retail outlets, sensory factors related to color, display patterns, and layouts can have significant effects on consumer behavior. Sensory elements have strong managerial relevance since they can non-consciously influence behaviors and because they are relatively easy to change; for example, it requires minimal effort to change the lighting or the music at a physical retail store or the display pattern for an online store. The eight papers in this special issue address theoretical and practical issues related to how different sensory elements can strongly influence retail practices. These papers focus on underexplored topic areas and also on emerging technologies, which stimulate thoughts for further research in these areas.     

虚拟公司治理视角下国有企业产学研公共地悲剧治理研究——基于寻租、合谋、机会主义行为抑制的中介效应检验

由于受到寻租、合谋、机会主义等行为的影响，我国产学研战略远未达到预期目标。虚拟公司的公司治理理论可以为产学研在理论和实践上的发展提供引导。经验性研究揭示了在寻租、合谋、机会主义行为中介效应下，产学研虚拟公司治理对产学研公共地悲剧治理的微观促进机理。因此，我国应优先完善产学研虚拟信息披露，再逐步优化其他虚拟公司治理要素，使产学研尽早摆脱被动局面。     

Revitalising serial entrepreneurship in sub-Saharan Africa: insights from a newly emerging economy

In light of the growing national priority to develop and revitalise entrepreneurship in emerging economies, our understanding of barriers to serial entrepreneurship (SE) in such a context warrants further scholarly attention. Using insights from Ghana, an integrated framework of endogenous and exogenous barriers to SE is advanced. The study identified factors such as stigmatisation of business failure, fear of failure, successive governments’ suspicion of the private sector and lack of a clear national policy as barriers to the development of SE. By creating conditions for de-stigmatising of failure, countries would be able to create conditions for more serial entrepreneurs to emerge and flourish. The analysis also indicates that reinvigorating entrepreneurship by providing space and opportunity for failed entrepreneurs to re-emerge would enable such countries to enhance entrepreneurial activities and improve economic development. The implications for technology analysis and strategic entrepreneurship literature are identified and examined.

Blockchain for tracking serial numbers in money exchanges

Money exchange is one of the most common day‐to‐day activities performed by humans in the daily market. This paper presents an approach to money tracking through a blockchain. The proposed approach consists of three main components: serial number localization, serial number recognition, and a blockchain to store all transactions and ownership transfers. The approach was tested with a total of 110 banknotes of different currency types and achieved an average accuracy of 91.17%. We conducted a user study in real‐time with 21 users, and the mean accuracy across all users was 86.42%. Each user gave us feedback on the proposed approach, and most of them welcomed the idea.     

Some issues in blockchain for accounting and the supply chain,with an application of distributed databases to virtual organizations

This paper reviews some recent blockchain‐based applications for information capture, distribution and preservation. As part of that review, this paper examines two key concerns with current blockchain designs for accounting and supply chain transactions: data independence and multiple semantic models for the same information distribution problem. Blockchain applications typically integrate database, application and presentation tiers all in the same ledger. This results in a general inability to query information in the ledger and other concerns. Further, since most applications appear to be private blockchain applications, there is a concern of agents needing to accommodate multiple blockchains depending on who their trading partners are and what they request. Finally, this paper uses a distributed database to design a ‘blockchain‐like’ system for virtual organizations.     

The Impact of Students’ Cultural Intelligence on Their Psychological Safety in Global Virtual Project Teams

This study addresses a call for the design and implementation of course curricula that prepare students to develop their CQ and gain experience working with peers on global virtual project teams. We explored how US-based and Peru-based students’ cultural intelligence (CQ) impacted their sense of psychological safety (PS) during a month-long global, virtual team project. We also examined the students’ people-focused (PF) and task-focused (TF) behaviors as mediators of the CQ-PS relationship. The results of mediation analyses provide support for our hypothesis that the relationship between cultural intelligence and psychological safety will be mediated by people-focused behaviors. Finally, we provide a model and suggestions for virtually bringing together students from different countries to collaborate on a global virtual project, and avenues for future research. Here we encourage a focus on a curriculum that educates students about their cultural intelligence and ways to develop psychologically safe learning environments. We also highlight the potential learning for faculty teaching such courses, and note how our experience collaborating with our counterpart in Peru constituted a fractal of what our students were experiencing on their global projects.

虚拟品牌社区顾客体验会带来其价值共创行为吗--基于手机虚拟品牌社区的实证研究

本文以顾客体验为切入点,基于价值共创理论、心理所有权理论和互惠规范理论,并运用于S-O-R理论框架,构建了虚拟品牌社区下,顾客参与价值共创行为产生的影响路径模型,通过问卷调查与实证分析得出:第一,顾客信息体验和娱乐体验越强,其参与价值共创的意愿程度越高,心理所有权部分中介了二者的促进关系;互动体验强化了社区顾客的心理所有权,并经由心理所有权的完全中介提高其参与共创意愿。第二,顾客参与共创意愿程度越高,其价值共创行为就越容易出现,社区的互惠规范正向调节了二者的关系。
