基于角色视角的分享经济信任机制研究

基于信任理论，从不同角色视角探究各信任要素对分享经济行为意图的影响。通过构建分享经济信任机制概念模型以及实证检验发现：从需求方视角来看，对个体（供给方）3个维度（能力、正直和善意）的信任、对平台善意的信任以及对产品能力的信任对需求意图产生积极地影响。从供给方视角来看，对个体（需求方）能力的信任和对平台3个维度（能力、正直和善意）的信任对供给意图有正向的影响。需求方更关注人与人之间的信任，而供给方则更看重对平台的信任。通过进一步比较还发现，需求方对平台和个体（供给方）的信任聚焦于善意信任，但供给方则是侧重于对平台和个体（需求方）能力的信任。

Knowledge sharing,knowledge leaking and relative innovation performance: An empirical study

External knowledge sharing and knowledge leakage often pose a strategic dilemma when firms conduct innovation activities. In this study, we focus on the positive and negative effects of this phenomenon. In particular, we empirically examine the effects of a firm׳s external knowledge sharing on its relative innovation performance under the contingencies of accidental and intentional leakage of business-critical knowledge. Results based on a survey of 150 Finnish technology-intensive firms show that external knowledge sharing has a positive effect on innovation performance, but high levels of accidental and intentional knowledge leakage by a firm׳s employees negatively moderate this relationship. These results contribute to the understanding of the potentially positive and negative issues related to external knowledge sharing and knowledge leakage, which have thus far remained empirically under-researched.     

Managing security risks for inter-organisational information systems: a multiagent collaborative model

Information sharing across organisations is critical to effectively managing the security risks of inter-organisational information systems. Nevertheless, few previous studies on information systems security have focused on inter-organisational information sharing, and none have studied the sharing of inferred beliefs versus factual observations. In this article, a multiagent collaborative model (MACM) is proposed as a practical solution to assess the risk level of each allied organisation’s information system and support proactive security treatment by sharing beliefs on event probabilities as well as factual observations. In MACM, for each allied organisation’s information system, we design four types of agents: inspection agent, analysis agent, control agent, and communication agent. By sharing soft findings (beliefs) in addition to hard findings (factual observations) among the organisations, each organisation’s analysis agent is capable of dynamically predicting its security risk level using a Bayesian network. A real-world implementation illustrates how our model can be used to manage security risks in distributed information systems and that sharing soft findings leads to lower expected loss from security risks.     

Enablers for end‐user entrepreneurship: An investigation on Italian food bloggers

This article examines unconventional entrepreneurship (accidental or end‐user entrepreneurs) to determine whether the decision‐making phase of the entrepreneurial process is collective. The analysis identified a virtuous circle that links knowledge, innovation, judgment, and decision making to collective interactions built on passion, experience, and sharing. To study food bloggers as unconventional user entrepreneurs, data were collected and analyzed using netnographic analysis. A supplementary online survey of food bloggers and their followers was also performed. Three groups of food bloggers are identified: amusing, functional, and fervent. Only fervent food bloggers, thanks to the virtuous circle built on passion, experience, and sharing as enablers, can be considered accidental or end‐user entrepreneurs.     

The Home Bias in Equities and Distribution Costs

We show that incorporating distribution costs into a general equilibrium model of international portfolio choice helps to explain the home bias in international equity investment. Our model is able to replicate observed investment positions for a wide range of parameter values, even if agents have an incentive to hedge labor income risk by purchasing foreign equity. This is because the existence of a retail sector affects both the correlation of domestic returns with the domestic price level and the correlation between financial and non‐financial income.     

发包方与供应商间关系对供应商创新能力的影响

采用多元层级回归方法,对影响供应商创新能力的驱动因素以及供应商在供应链网络中的等级位置对各驱动因素与供应商创新能力间关系的调节作用进行了理论探讨和实证分析。结果显示:在跨国外包情景下,发包方支持、共享活动和联结强度对供应商的创新能力具有显著的积极影响;供应商在供应链网络中的等级位置对联结强度与供应商创新能力间关系具有显著的正向调节作用,对共享活动与供应商创新能力间关系的正向调节作用不稳定。     

A general framework for price regulation of airports

Price cap regulation (PCR) was first implemented for privatized utilities in the UK in the 1980s. It has since been adopted by numerous countries as a regulatory regime in several sectors. This paper focuses on the development of different forms of price regulation of airports of which PCR is one variant. In countries where airport privatization is still in the early stages, the spectrum of airports and varied nature of regulatory regimes can be confusing and the lack of a general framework can itself become an obstacle to privatization. This paper proposes a general framework comprising decisions to be made for seven variables which is able to accommodate the diversity of airports and varied approaches that may be required as well as transitions between approaches. These approaches include light-handed regulation, price or revenue yield caps, rate of return regulation, earnings sharing, as well as choice of till.

The Primacy of Space in Politics: Bargaining Rights,Freedom and Power in an İstanbul Neighborhood

This article explores and theorizes the ways in which urban space and political contestations are mapped onto each other. The ethnography illustrates the multifaceted transformations in a notoriously secularist neighborhood of ?stanbul, Te?vikiye, as it first turns into a high‐consumption locality in the post‐1980s, then into a high‐conflict urban space in the new millennium on the arrival of Muslim high‐spenders, particularly headscarved women. Aiming to fill the gap left by the absence of spatial analysis from political science and political sociology, I argue that the urban neighborhood becomes central for political contestation when both government and opposition fail to protect and secure liberties and rights. Now that devout Muslims are integrated into highly contested urban sites and share bourgeois lifestyles, ordinary people act in defense of their ‘sphere’ of freedom and privacy. This new territoriality is largely symptomatic of increasing fears of losing freedom, privacy and social status. This spatial defensiveness is reinforced by people's decreasing trust in, and increasing demands from, the state for the protection and security of their rights and liberties. My overarching argument is that exclusive attention to the bipolar clash between devout Muslims and secularists under the rubric of ‘neighborhood wars’ obscures multipolar conflicts around the discontents stemming from authoritarianism and democratization.
