环境库兹涅茨曲线假说及其在中国的检验

经济与环境协调发展是我国经济发展中的重大课题。本文从环境库兹涅茨曲线假说出发,利用中国各个省市区1989～2004年数据建立面板数据模型,运用固定效应模型和随机效应模型对其进行估计,以此剖析我国经济增长与环境污染水平的演变规律。结果表明,环境库兹涅茨曲线假说在我国并不成立。因此,我国不能盲目重复发达国家"先污染,后治理"的传统模式,而应该走环境与经济持续协调发展的道路。     

健康风险冲击对农户收入的影响

大股东对上市公司掏空与支持的经济学分析

在公司的所有权安排中,大股东拥有公司的控制权,有能力为获取控制权的私人利益而侵占上市公司的资源。但是,当上市公司陷入经营困境时,大股东可能通过减少自己的侵占行为而使公司具有偿债能力,甚至会用自己的资源进行支持以防止公司破产。如果上市公司的投资回报率低于大股东的预期水平,或者预期上市公司无法继续生存下去时,大股东会以公司外部股东和债权人的利益为代价而对上市公司进行掠夺。

Strategic Internet application trends in supply chain management

The Internet is evolving as a powerful force in the new marketplace where the nexus of competition has changed from individual firms to efficient supply chain networks both between firms and within industries. This study explores Internet adoption patterns and operational applications in US supply chain networks. The data reveal that the integration of the Internet into supply chain management applications has increased and has moved away from indiscriminate application of novel Internet technologies towards becoming a focused endeavor with precise expectations and measurable goals. Specifically, the study finds that Internet usage within supply chains is maturing as evidenced by enhanced and increased productivity, reduced costs and increased profit for participating firms.     

Sustainability assurance provider participation in standard setting

This paper examines the participation of accounting firms in the development of sustainability standards by the Securities and Exchange Commission (SEC) and the Sustainability Accounting Standards Board (SASB). This study shows that the Big Four accounting firms have an active role in both the submission of comment letters on sustainability to the SEC and participation in the industry working groups (IWG) for the SASB. The SASB participation reveals that individuals located within the US and at international affiliates are participating at earlier career stages. In addition, this paper leverages LinkedIn data, identifying the career path of the individuals subsequent to their participation with the IWG, to determine how large accounting firms are retaining the skills and knowledge necessary for this field. Since the Big Four firms are market leaders in sustainability assurance, the finding that Big Four firms can retain individuals with financial assurance backgrounds differently than individuals with other backgrounds speaks to the unique skill set that financial assurance develops. This suggests that the career opportunities for interested financial assurance individuals within the sustainability sphere remain robust within the Big Four environment.
