控制权及投资者保护对掏空风险的影响——基于融资规模的经验证据

基于中国上市公司融资规模数据对上市公司的控制权与掏空风险的关系进行了实证分析,并探讨了投资者保护对掏空风险的抑制作用。研究发现:与国家终极控制的上市公司相比,私人终极控制的上市公司中掏空风险更高,因而融资规模显著高于前者;控股股东持股比例越高,掏空上市公司的动机越小,从而导致上市公司融资规模越低;其他大股东的制衡能力越强,控股股东掏空上市公司的可能性越小,因而上市公司融资规模越低;投资者保护水平越高,越能起到抑制掏空风险的作用。     

城乡一体化进程中乡村土地利用效益评价

文章在实地(河北省邢台市)调研基础上,通过文献分析与成本分析相结合的方法对城乡一体化进程当中乡村土地利用效益进行系统的评价,并在此基础上揭示出目前我国在城乡一体化进程当中乡村土地利用过程当中存在的问题,并给予相应的建议。研究结果表明:我国城乡一体化进程当中,对我国乡村土地利用效益影响较大的主要因素有政府政策不合理、对于土地利用效益缺乏足够认识,这些原因直接导致在城乡一体化进程当中乡村土地耕地边际化现象严重、城市建设用地规模过大、土地生态效益低下及乡村土地配置不合理等现象的出现。基于对土地效益评价与我国目前乡村土地利用状况的深入分析,该文认为应从土地的经济效益、社会效益及生态效益对于目前城乡一体化进程当中存在的土地利用效益偏低的现象进行整改,例如提高土地的集约度,实行大规模的机械化生产进而提高土地的经济效益;通过合理规划商业用地、居民住房用地及农业用地的比例提高土地的社会效益;发展多种形式的生态养殖与特色旅游业促进土地生态效益的提高。     

Environmental Governance of Enterprises and their Economic Upshot through Corporate Reputation and Customer Satisfaction

Drawing on resource‐advantage and signalling theories, we investigate two mechanisms, namely corporate reputation and customer satisfaction, by which the environmental governance of enterprises can benefit their economic performance. Based on secondary data from the 500 largest US enterprises compiled from multiple sources, our findings contribute to the literature by establishing the link between corporate reputation and green reputation. We also establish the economic performance paths of environmental governance via corporate reputation and customer satisfaction. This study expounds on why ‘green’ matters and identifies the performance roles of two corporate strategic resources extractable from the environmental governance of enterprises.

The effects of rational and habitual factors on mode choice behaviors in a motorcycle-dependent region: Evidence from Taiwan

This paper aims to explore the effects of rational and habitual factors on mode choice behaviors in a motorcycle-dependent region. Both a discrete choice model and theory of planned behavior (TPB) are employed to examine mode choice behaviors. A sample was obtained from two major cities in Taiwan to examine the contextual effect of public transport development. The empirical results reveal that psychological (rational and habitual) factors have stronger influences on mode choice behaviors than socio-economic factors, and furthermore that habitual factors explain traveler mode choice behaviors better than rational ones. The contextual effect with regard to public transport development is found to be significant for motorcyclists' mode choice behaviors. The practical implications of the results of this study are discussed.     

江苏沿海地区城市化现状及存在问题浅析

2009年江苏沿海开发上升为国家战略。为了解该地区的发展态势,本文立足城市化视角,具体分析了该地区城市化现状及存在问题。通过客观考察,本研究发现该地区面临一些困境,包括城市化率偏低、城市经济薄弱、社会事业滞后、城市间分工合作不够协调等。不过,总体上江苏沿海面临的机遇依然多于挑战。

交易成本与新型农村合作医疗制度可持续发展

新型农村合作医疗制度的试点极大地推进了我国农村医疗保障制度的构建过程,但是该项制度推进并不顺利。本文试从交易成本理论视角,分析当前新农合制度存在较高的交易成本导致制度创新不足。在此基础上,本文提出要使新农合制度可持续发展,政府必须从制度完善和机制创新两个方面降低交易成本,以提高新农合制度绩效。     

Does a stricter enforcement policy protect the environment? A political economy perspective

The conventional wisdom suggests that a stricter enforcement policy can reduce pollution emissions. Nevertheless, this present paper argues that this assertion does not necessarily hold if the stringency of environmental regulation is subject to the influence of lobbying. A stricter enforcement policy increases the polluters’ expected financial burden, and induces them to exert greater political pressure on reducing the stringency of environmental regulation, thereby resulting in a larger amount of pollution emissions. We also show that tightening the enforcement policy can reduce efficiency. We highlight the possibility of policymaking being misguided due to overlooking the political effect of enforcement policy.     

A Generic Framework for Automated Multi-attribute Negotiation

Agents in a negotiation may have to negotiate multiple issues simultaneously. Automated multi-attribute negotiation provides an important mechanism for distributed decision makers to reach agreements on multiple issues. Moreover, it also furnishes the opportunity to reach “win–win” solutions. In this paper, we first provide a survey that synthesizes the research on multi-attribute negotiation. We discuss the limitations of the existing research and conclude that three key issues need further study: incomplete information, Pareto optimality, and tractability. We then present a generic framework for automated multi-attribute negotiation with two new mechanisms that address the above issues. Finally, we discuss the challenges and directions for future work.
