我国上市公司董事会效率与公司绩效的实证研究 总被引:1,自引:0,他引:1
该文以2008年在深圳交易所上市的公司为样本,采用定性定量结合的方法,将董事会效率特征量化为5个指标,提出合理假设,建立多元线性回归模型,对董事会效率与公司经营绩效的关系进行了实证分析.实证检验结果发现董事会规模与公司经营绩效存在显著的负相关关系;外部董事比例与公司经营绩效存在显著的正相关关系;董事会领导结构、董事会会议次数和董事会持股比例与公司经营绩效不相关. 相似文献

本文以我国沪、深股市2005~2007年的上市公司为样本,以产品市场竞争、董事会治理以及企业技术创新为研究对象,通过实证研究的方法,揭示基于不同产品市场竞争度下董事会规模、结构以及董事长与总经理是否两职合一对企业技术创新的影响作用。实证结果发现不论在高竞争行业还是低市场竞争行业中董事会规模与企业技术创新为均负相关关系;在高、低竞争度行业中,企业的内部董事比例与技术创新水平均为正相关关系;独立董事比例在高、低竞争度行业中与企业技术创新水平相关性均没有通过检验;董事长与总经理的两职合一在高、低竞争度行业中与企业的技术创新水平均为正相关关系。 相似文献

Brander&Lewis(1986)研究了公司资本结构对于产品市场行为的影响,首次将产业组织理论和公司金融理论融合起来。后续的研究发现:资本结构决策与产品市场竞争行为之间存在互动关系。资本结构能影响企业产品市场竞争绩效,而产品市场竞争又反过来影响公司资本结构的选择。本文通过借鉴Camapello模型,对我国造纸印刷类上市公司2005-2009年的面板数据进行实证分析;结果发现,我国上市公司市场竞争力与资产结构之间的回归系数为正,但不显著。 相似文献

董事会结构、战略决策参与程度与公司绩效 总被引:10,自引:0,他引:10
通过对中国101家上市公司的实证研究发现:独立董事的数量与董事会战略决策参与程度不相关,董事长与总经理两职分任比两职兼任更有利于提高董事会战略决策参与程度,董事会规模与战略决策参与程度负相关,董事会战略决策参与程度与公司财务业绩正相关.研究发现独立董事功能的发挥还很不明显,仍然需要加大改革的力度. 相似文献

We examine the impact of board cultural diversity, based on directors' ancestry, on firm performance conditional on product market competition. We argue that culturally diverse boards foster critical thinking and offer creative solutions that help firms thrive in competitive environments. We document that culturally diverse boards are associated with superior performance for firms operating in highly competitive industries. To address potential endogeneity issues, we use a quasi-natural experiment of the U.S. import tariff cuts. The positive impact of board cultural diversity on firm performance in competitive markets manifests itself in firms that innovate more, require creative inputs, and face heightened predation risk due to their high interdependence with industry rivals, in line with culturally diverse boards effectively performing their advisory role. Lastly, we find no evidence that board cultural diversity is associated with enhanced monitoring as its benefits fade in the presence of powerful CEOs. 相似文献

Abstract: The board of directors is generally seen as an important internal governance structure. However, the empirical evidence on the board‐performance relationship is not conclusive. On the other hand, a growing literature suggests that different control mechanisms, either internal or external to the firm, can interact with each other and affect performance. One such important factor is product market competition. The objective of the study is to investigate further the board‐performance relationship taking into consideration the potential effect of market competition. More precisely, the study analyzes the combined effect of boards of directors' characteristics, and market discipline on firm performance. Overall, the results suggest that competition has a positive and significant impact on firm profitability and productivity. Moreover, this determinant factor creates the conditions for which the board‐performance relationship is supported. In other words, for boards to be effective, firms should be exposed to a competitive environment. 相似文献

商业银行董事会治理:特征与绩效——基于美国银行业的实证研究 总被引:11,自引:0,他引:11
本文以1996—2005年间美国43家商业银行为样本,实证分析了商业银行董事会治理的特征及其对绩效的影响。研究表明:平均而言,商业银行董事会的规模略大于非金融性企业的这一指标,且外部董事的比例较高;董事会规模与银行绩效之间存在非线性的倒U型曲线关系,但外部董事的比例对银行绩效的影响不显著;董事长与总经理两职合一、董事会次级委员会的数量、外部董事拥有的董事席位数均与银行绩效显著负相关;董事会会议频率对当年度银行绩效的影响不显著,但与前一会计年度的绩效之间存在显著的负相关关系;董事持股比例与银行绩效之间存在非线性的关系,而总经理任职年限对银行绩效的影响不显著。 相似文献

This study examines the association between the employment and composition of nominating committees with board and ownership characteristics. First, the results suggest that the likelihood of using a nominating committee is inversely related to the level of inside ownership and positively weakly, related to the independence, but not the number, of outside board members. Second, the percentage of insiders participating in the committee is positively related to inside ownership, and negatively related to proxies for outside director quality. Finally, outside directors are more likely to serve on the nominating committee the more outside directorships they hold, and the longer their tenure in the firm. The likelihood of insider committee membership rises with a director's equity investment, with board tenure, and with other committee memberships. Taken together, the results are consistent with nominating committees substituting inside ownership in controlling management, mostly improving board quality, and being staffed with independent, experienced, and knowledgable members. 相似文献

银行董事会特征、CEO报酬与银行绩效——基于对11家股份制银行的数据分析 总被引:1,自引:0,他引:1
本文通过采集2005~2008年11家已上市的全国股份制商业银行的数据,实证分析了银行董事会独立性与CEO报酬之间的关系,并在考虑银行CEO报酬内生性基础上,进一步检验了银行董事会独立性、CEO报酬和银行绩效的关系。研究结果显示:长任期的CEO、CEO兼任董事长、较大比例的内部董事和较大的董事会规模构成了中国上市银行的监管障碍。银行CEO的高薪酬是不足为奇的,因为高薪酬对应的是银行业绩的显著增长。CEO报酬是银行公司治理的强化机制,授予银行CEO合理的激励报酬可以克服银行监管障碍,提高银行治理水平。 相似文献

This paper looks at board composition determinants in New Zealand. We document that the proportion of outside board members is inversely related to insider equity ownership supporting the notion that these variables are substitute mechanisms in controlling agency problems. We also find that board composition is directly related to debt, ownership concentration, and profitability and inversely related to growth and firm size. There is evidence that firms with influential CEOs have lower outside board representation. Finally, we document that the passage of the legislation reforming company and securities laws in 1993 was associated with increased outside members on the board. 相似文献

We examine the link between the monitoring capacity of the board and corporate performance of UK listed firms. We also investigate how firms use the flexibility offered by the voluntary governance regime to make governance choices. We find a strong positive association between the board governance index we construct and firm operating performance. Our results imply that adherence to the board‐related recommendations of the UK Corporate Governance Code strengthens the board's monitoring capacity, potentially helping mitigate agency problems, but that investors do not value it correspondingly. Moreover, in contrast to prior UK findings suggesting efficient adoption of Code recommendations, we find that firms at times use the Code flexibility opportunistically, aiming to decrease the monitoring capacity of the board, which is followed by subsequent underperformance. This finding questions the effectiveness of the voluntary approach to governance regulation followed in the UK and in many countries around the world. 相似文献

This study examines the relationship between board diversity and firm value for Fortune 1000 firms. Board diversity is defined as the percentage of women, African Americans, Asians, and Hispanics on the board of directors. This research is important because it presents the first empirical evidence examining whether board diversity is associated with improved financial value. After controlling for size, industry, and other corporate governance measures, we find significant positive relationships between the fraction of women or minorities on the board and firm value. We also find that the proportion of women and minorities on boards increases with firm size and board size, but decreases as the number of insiders increases. 相似文献

Many financial economists argue that the board of directors' efficacy in the monitoring of managerial behavior depends upon the quality of the directors. Assuming that there is a link between the stock performance of target firms and the quality of their directors, we empirically categorize directors receiving additional directorships following a takeover as “above average” and “below average.” We then follow the stock performance of firms hiring new directors for three years after their hiring. We match the two categories of directors with the performance of hiring firms after a director's appointment. Accounting for other contemporaneous effects, we regress the hiring firms' post‐performance on director quality and other attributes. The results indicate that directors of “above average” quality are related to hiring firms with “above average” post‐performance. 相似文献

The board‐level technology committee (TC) could play a significant role in enterprise risk management. Unfortunately, only about 10 % of public companies have chartered such a committee. There is evidence that the TC mitigates the negative market reaction to data breaches (Higgs et al. 2016), suggesting that investors expect TCs to control operational IT risk—the risk associated with technology that facilitates the company's core operations, including external risk such as data breaches. Based on a review of 50 existing TC charters, we find that TCs today focus instead mainly on strategic risk—the risk associated with strategic product technology development—with under half of TCs including operational risk management in their charters. We see this as a potential disconnect between stakeholder expectations of risk management and company delivery on that expectation. 相似文献
