政府控制层级对公司价值的影响研究——基于A股上市公司的实证研究

中国特有的经济＂双轨制＂决定着上市公司受不同最终控制人的影响,由此造成不同控制性质的公司价值存在差异性。以2007-2011年中国所有A股上市公司作为研究样本,根据实际控制人性质将上市公司细分为非政府控制、县级政府控制、市级政府控制、省级政府控制以及中央政府控制这五种类型,实证分析了不同层级政府控制和非政府控制人对公司价值的影响。实证结果表明,相对于非政府控制上市公司,政府控制的上市公司价值更低,其中市级县级等低层级政府控制的上市公司价值更低。同时也发现政府控制的上市公司比例有显著性下降,说明中国经济主体转向非政府控制经济已初见成效。     

投资者保护、关联交易与公司绩效——来自长三角A股上市公司的经验证据

以2007~2009年长三角地区A股上市公司为研究样本,以投资者保护为切入点,分析投资者保护、关联交易对公司治理效率的影响。研究表明:长三角地区上市公司普遍存在控股股东,董事长来源于控股股东的公司关联交易明显多于其他公司,总经理来自控股股东的公司关联交易不明显,关联交易与投资者保护程度负相关,投资者保护程度与公司治理正相关。     

企业创新效率研究——来自股权质押的影响

本文结合我国实施创新驱动发展战略及股权质押频繁的现实背景,利用2006—2015年A股上市公司的数据,探讨控股股东的股权质押行为是否以及如何对企业的创新效率产生影响。研究表明,控股股东的股权质押行为会显著降低企业的创新效率。进一步地研究发现:(1)当第二类代理问题越严重,或质押风险越大时,控股股东股权质押行为抑制企业创新效率的作用越明显,表明控股股东股权质押伴随的掏空效应及短视效应,是导致二者负向关系的重要原因;(2)掏空效应和短视效应在影响控股股东股权质押与企业创新效率的关系上存在显著的替代效应;(3)研发投入强度下降时,控股股东股权质押对企业创新效率产生的负面效应更强。本文的研究不仅丰富了企业创新效率影响因素及控股股东股权质押经济后果的相关文献,对于规范控股股东股权质押行为,提高企业创新能力,实现创新驱动发展战略,也具有重要的启示意义。     

公司交叉持股的战略动因研究

交叉持股战略动因的基本理论主要包括战略联盟、公司治理、逆向选择成本和交易成本。本文以2006年我国沪深非金融上市公司为样本,主要检验公司治理、逆向选择和现金流量管理等三个理论。研究初步发现:(1)随着我国上市公司第一大股东持股或管理层持股超过一定比率后越高,管理层浪费公司资源进行股权投资的倾向越小,公司交叉股权投资比率相应越小;(2)交叉持股起到了金融缓冲的作用,以为新增的长期资产投资提供内部资金支持,降低因外部融资造成的潜在逆向选择成本;(3)当现金流入流出不同步的时候,交叉持股作为一个流动性缓冲器,构成投资者现金流量管理系统的一部分。     

Aligning debt and equity claimant interests: Evidence from dual claim investors

This study investigates how investors that own both equity and debt in the same firm affect other shareholders in the firm. It documents that dual claim investors are quite prevalent among the industrial firms listed in the Russell 3000, with over 20% of them having a bank holding company that owns both debt and equity in the firm. The results imply that shareholders are substantially impacted by the presence of dual claim investors in firms, suggesting that relatively small ownership stakes by dual claim banks are associated with greater conflicts of interest among shareholders and debt holders; while relatively large bank equity stakes may benefit outside shareholders when aligned with loan by dual claim banks because they improve bank monitoring incentives and reduce the agency cost of debt.     

Investigating the effect of board independence on performance across different strategies

This study investigates the effect of board independence on performance across different strategies. Using moderated regression analyses, the results confirm our hypothesis that board independence has a significantly more positive effect on performance for firms pursuing a strategy of cost efficiency than for those pursuing a strategy of innovation. The results of this study indicate that consideration of firms' competitive strategy can provide a better understanding of the relationship between board independence and firm performance.     

Do common owners influence corporate social responsibility? Firm-level evidence from China

Using a sample of Chinese A-share listed companies from 2007 to 2018, this article explores the influence of common owners on corporate social responsibility (CSR). The results show that common owners significantly promote CSR investment, indicating that increased CSR represents a bright side to common owners, in contrast to their anticompetitive effect. Further analysis shows that the nature of state ownership significantly weakens the positive relationship between common owners and CSR investment. Prospector firms strengthen the positive influence of common owners on CSR investment, whereas defender firms weaken the effect. Moreover, common owners benefit from increasing CSR investment, and co-owned firms benefit by easing their financial constraints when they invest or increase their investment in social responsibility. The findings enhance the outstanding of how common owners affect corporate behavior and enrich the literature on common ownership and CSR investment.     

公司社会责任履行对财务业绩的影响--基于发布企业社会责任报告下的研究

文章以2011～2012年披露企业社会责任报告的486家上市公司为样本,运用OLS回归方法,实证检验上市公司在发布企业社会责任报告的情况下,公司社会责任对财务业绩的影响。研究结果表明：上市公司多次发布企业社会责任报告能够促进公司财务业绩;公司履行社会责任能够直接促进公司财务业绩的提高;上市公司履行社会责任可以通过发布企业社会责任报告提高公司财务业绩。     

Corporate social responsibility and financial performance: the “virtuous circle” revisited

We examine the causal relation between corporate social responsibility (CSR) and financial performance. Consistent with past studies, we find that the two variables appear to be related when we use traditional statistical techniques. However, using a time series fixed effects approach, we find that the relation between CSR and financial performance is much weaker than previously thought. We also find little evidence of causality between financial performance and narrower measures of social performance that focus on stakeholder management. Our results suggest that strong stock market performance leads to greater firm investment in aspects of CSR devoted to employee relations, but that CSR activities do not affect financial performance. We conclude that CSR is driven more by unobservable firm characteristics than by financial performance.

国外公司公民思想研究新进展

公司公民思想是20世纪90年代公司社会责任概念与利益相关者理论相融合的产物,先是由公司在实践层面运用,然后得到了政府的推动,最终激发了学者们的研究热情。公司公民思想的内涵由初期的局部观逐步发展到目前的营销工具观和战略投资观,公司公民思想的发展历经初始、参与、创新、整合和转型五个阶段,公司公民思想发挥作用需要具备一定的制度条件。     

Do women managers keep firms out of trouble? Evidence from corporate litigation and policies

We find that firms where women have more power in the top management team, measured by female executives’ plurality and pay slice, face fewer operations-related lawsuits. This effect is robust to several treatments of endogeneity and does not appear to be driven by female executives' greater willingness to settle the cases. Evidence from a simultaneous equations approach suggests that firms where women executives have more power avoid lawsuits partly by avoiding some risky but value-increasing firm policies, such as more aggressive R&D, intensive advertising, and policies inimical to other parties.     

Are red or blue companies more likely to go green? Politics and corporate social responsibility

Using the firm-level corporate social responsibility (CSR) ratings of Kinder, Lydenberg, Domini, we find that firms score higher on CSR when they have Democratic rather than Republican founders, CEOs, and directors, and when they are headquartered in Democratic rather than Republican-leaning states. Democratic-leaning firms spend $20 million more on CSR than Republican-leaning firms ($80 million more within the sample of S&P 500 firms), or roughly 10% of net income. We find no evidence that firms recover these expenditures through increased sales. Indeed, increases in firm CSR ratings are associated with negative future stock returns and declines in firm ROA, suggesting that any benefits to stakeholders from social responsibility come at the direct expense of firm value.
