公司治理结构和自愿性信息披露关系的实证研究

本文选取了2002年169家中国上市公司作为研究样本，检验了公司治理结构的四个因素即董事会中独立非执行董事的比例、监事会人数、审计委员会、董事长是否兼任总经理与自愿性信息披露程度的关系。研究结果表明，董事长不兼任总经理的公司。其自愿性信息披露程度就比较高，而其余三个公司治理因素并没有对自愿性信息披露程度产生影响。     

Trade intensity,country size and corruption

Abstract. Several authors claim to provide evidence that governmental corruption is less severe in countries where trade intensity is higher or populations are smaller. We argue that theory is highly ambiguous on these questions, and demonstrate that empirical links between corruption and trade intensity – or country size, strongly related to trade intensity – are sensitive to sample selection bias. Most available corruption indicators provide ratings only for those countries in which multinational investors have the greatest interest: these tend to include almost all large nations, but among small nations only those that are well-governed. We find that the relationship between corruption and trade intensity disappears, using newer corruption indicators with substantially increased country coverage. Similarly, the relationship between corruption and country size weakens or disappears using samples less subject to selection bias.

The effect of interfirm dependence structures on governance mechanisms

Despite recent developments regarding the study of interdependence structures, previous research has rarely investigated the simultaneous effect of both interdependence magnitude and interdependence asymmetry on governance mechanisms among exchange parties. A survey of manufacturing companies has been used to test a theory about the interactive effect of buyer dependence and supplier dependence on inter-firm governance. The analysis of the survey supported the proposition that both buyers and suppliers that are highly dependent on each other (high interdependence magnitude and low interdependence asymmetry) may choose to rely on monitoring and the norm of information sharing. However, when a buyer's dependence is low regardless of the supplier's dependence level, the buyer does not rely on the norm of information sharing (buyer's relative interdependence advantage, buyer's relative interdependence disadvantage, and low interdependence magnitude). On the other hand, when the supplier's dependence on the buyer is low, the buyer relies on monitoring regardless of its dependence level (buyer's relative interdependence disadvantage and low interdependence magnitude). However, this study did not empirically measure performance. Further research should be done on the effect of congruence between the governance mechanism and its antecedents on buying performance.     

我国城市农民工劳动供给曲线的理论分析和实证检验

从我国存在巨大的区域经济差异出发,如果假定劳动力从落后地区向发达的城市转移,不是决定于两地区的工资之差,而是决定于城市的工资与落后地区劳动力在城市的生存成本和需要其负担的家属在落后地区的生存成本即转移劳动力的基础价值之差,并且假定在城市的劳动力供给市场上,随着工作时间的延长和实际小时工资的降低,存在劳动力的退出,并且退出劳动力减少的劳动供给大于留在劳动力市场中的劳动者增加的劳动量,则城市农民工的劳动供给曲线是一条以落后地区转移劳动力的最低基础价值为起点、向右上方倾斜、其不同阶段存在不同斜率、且斜率随城市劳动力供求状况而变动的曲线.     

机构投资者与公司治理

随着机构投资者的发展壮大,人们越来越关注其对公司治理方面的作用。由于机构投资者巨大的股票持有量,他们存在参与公司治理的愿望。但因为经济往来关系、法律法规规定、信息处理障碍导致机构投资者并不能有效地参与公司治理。     

Organizational Culture: A Framework and Strategies for Facilitating Employee Whistleblowing

Seven dimensions of organizational culture that influence the employee reflection process that ultimately leads to whistleblowing behavior are presented. These include 1) vigilance, 2) engagement, 3) credibility, 4) accountability, 5) empowerment, 6) courage, and 7) options. Key considerations within each dimension are discussed and a compliance framework is used to identify strategies for encouraging a culture that supports employee communication, questioning, and reporting of illegal, unethical, and illegitimate practices within organizations.     

基于共同治理模式下的公司业绩评价指标体系探索

现代企业理论认为,企业是一系列合约的组合,其中最重要的是企业所有权合约,提高企业所有权安排效率的出路是资本所有者拥有剩余索取权与剩余控制权。在这种理论的基础上产生了“股东至上”理论,公司治理采用“股东至上模式”,与此相适应产生了相关的业绩评价体系。但是这种治理模式和业绩评价体系都存在着缺陷,为适应现代公司经营环境的变化,笔者认为,应该采用“共同治理模式”代替“股东至上模式”,并建立与之相适应的业绩评价体系。     

城乡收入差距对城镇失业的影响及对策分析

当前我国城乡收入差距日益扩大引发了庞大的乡-城人口流动,在一定程度上加剧了城镇的高失业状况.正确认识这种状况,需要运用适当的理论,予以科学的分析.利用托达罗模型对此现象进行了理论分析,并利用格兰杰因果关系检验方法对城乡收入差距加剧我国城镇失业问题进行了实证检验,最后提出了短期内利用新农村建设缓解我国城镇失业压力的政策措施及建议.

资本结构在我国上市公司治理中作用的实证分析

本文以1994～2002年间沪市上市公司为对象，研究了样本公司的资本结构特征，考察了总负债比、长期负债比和流动负债比与总资产收益率以及净资产收益率之间的关系，对资本结构在我国上市公司治理中的作用进行了实证分析。研究结果发现我国上市公司资本结构无法发挥在公司治理中的作用。本文分析了原因并提出了相应的对策。
