FDI区位选择因素研究--对我国三大经济圈及中西部地区的实证研究

文章采用面板数据(panel data)回归模型分析了1995～2002年中国178个城市的外商直接投资(FDI)的区位选择因素和聚集效应,并对长三角、珠三角、环渤海和中西部四个城市组群的FDI区位选择模式进行了比较分析.结果说明:从全国来看,人均GDP、土地成本、聚集效应、交通状况和教育水平是影响FDI的主要因素;长三角、珠三角、环渤海以及中西部地区的FDI区位选择模式各有不同,突出表现在:聚集效应在环渤海地区不显著;工资成本已经开始对长三角地区的外资分布产生影响,但在其他地区仍不显著;教育水平在长三角和环渤海地区影响显著,但在珠三角和中西部地区影响不显著.

农民工与都市和谐发展探索

大量农民工南下给广州输送了充足的劳动力,促进了广州经济的发展,但农民工的发展与高速发展的大都市不适应。本文认为,不适应的原因有农民自身的原因,也有城市本身的因素,探索农民工的生存发展与都市和谐发展相统一的新路子,要从提高青年农民工的素质入手,为其创造成才的社会氛围,创建和谐、公正、平等的工作环境与生活环境。

高油价时代保障国家石油安全之策

1999年以来,国际油价增长了近7倍,屡次突破历史高点.前不久,已连续数月在每桶75美元左右徘徊.由此可见,世界正迈入一个高油价时代.作为世界石油第二大消费国,高油价已对我国石油安全构成一定的影响.我国经济建设的焦点之一在能源,而能源安全的核心在石油.保障石油安全是实施国家能源安全战略最重要的一环,须予以高度重视,并采取切实可行的对策.     

基于信息化社会会计假设的反思

随着网络技术的发展与应用,对财务会计提出了挑战,有学者认为,传统的财务会计假设已不再适用。本文认为,信息化只是在一定程度上影响了会计假设,并没有改变会计假设的实质,会计假设在会计理论和会计实务中的地位并未发生实质性的动摇。采用实时报告系统,能够有效解决信息化对会计分期假设和持续经营假设的影响。

Carbon Disclosure,Financial Transparency,and Agency Cost: Evidence from Chinese Manufacturing Listed Companies

Given the constraints on carbon emissions due to their impact on global warming, carbon disclosure has become an important way to deliver signals to the market. We examine the benefits associated with carbon disclosure from the standpoint of corporate social responsibility (CSR) for China’s manufacturing industries from 2010 to 2014. We divide corporations into heavily polluting and non-heavily polluting groups in order to control the industry factor. Based on the Principal-Agent Theory, we empirically test the relationship between carbon disclosure and financial transparency, and we evaluate the effect of carbon disclosure on agency costs and operations. Our results highlight that carbon disclosure is negatively associated with agency costs. However, we do not find enough evidence to prove what role financial transparency plays in the relationship between carbon disclosure and agency cost. Therefore, the influence of financial transparency as a mechanism is not yet clear. This study provides a way to look at the intentions of firms that disclose carbon information, and it also enhances the literature on carbon disclosure and agency costs in China based on Chinese data.     

The Effect of Ultimate Ownership on the Disclosure of Environmental Information

This study empirically examines whether environmental information disclosure (EID) is influenced by the characteristics of a firm's ultimate owners. Based on the EID of publicly listed firms in China, we qualitatively measure the quality of EID of each firm and link those quality scores to firm characteristics to understand the determinants of EID. We further link the EID scores to market valuation of the firm through the Ohlson valuation model to understand whether the market appreciates EID. Our results show that EID is more likely for government‐controlled firms, firms with less hierarchy in their ultimate ownership and firms with more discrepancy between voting rights and cash flow rights. Our results also indicate that the stock market appreciates environmental issues and that EID itself, as well as disclosure quality, is associated with a higher market valuation. Our results still hold with the endogeneity issue controlled.
