文章以我国1995~2005年的银行数据为样本,比较分析一直以来都让世人所关注的我国不同所有制商业银行的规模经济问题。在对国内外有关银行业规模经济问题研究的文献综述基础上,通过大量相关具体数据对我国银行业的市场结构及效益问题进行经验性的判断比较,最后运用超越对数成本函数对我国国有商业银行与股份制商业银行的规模经济问题进行实证比较分析,并得出结论:从总体上看,我国商业银行规模系数变化不大,但近几年来在规模效率方面,国有商业银行相对于股份制商业银行来说进步更为显著。 相似文献

Low productivity growth in New Zealand has been a paradox. We study New Zealand firms’ profitability, in terms of profit margin and return on assets (ROA), from the viewpoints of productivity enablers using firm-level panel data. We find that tangible fixed investment and a research and development (R&D) tax incentive are associated with higher profitability performance. In addition, the firm size is found to be a key determinant of profit margin. By contrast, we do not find any evidence that intangible investment can improve the profitability. The global financial crisis has not changed the leverage effect on ROA in New Zealand, while the impact of R&D became more prominent after the crisis. 相似文献

从内部控制角度出发,以我国2008—2013年度沪深两市A股上市公司为研究样本,在研究内部控制与公司价值之间关系的基础上考察公司高管权力配置结构对两者之间关系的影响,并进一步分析不同产权性质下内部控制与公司价值之间的关系以及高管权力对两者关系的影响,结果表明:完善的内部控制有助于提升公司价值,高管权力过于集中会削弱内部控制的有效性并抑制内部控制对公司价值的提升作用;与国有上市公司相比,非国有上市公司的内部控制对公司价值存在显著的提升作用,但在高集权的情况下,无论是国有上市公司还是非国有上市公司,内部控制均不能对公司价值起到显著的提升作用。 相似文献

This study addresses the issue of the relative degree of variance in ROA accounted for by industry, corporate, and SBU effects while controlling for the business cycle and the interaction between the business cycle and industry. Two key articles, Schmalensee (1985) and Rumelt (1991), are discussed in detail. Research results on a recent data base (COMPUSTAT), using variance components analysis (VARCOMP) are presented that not only confirm most of the Rumelt (1991) findings, but also suggest the existence of a corporate effect, heretofore undetected. 相似文献

股权激励制度设计的初衷是为了减弱代理问题,因此考察股权激励的实施效果应该首先直接考察它能否缓解经理人的代理问题,然后才是对公司绩效的影响.利用2006-2014年我国沪深两市A股上市公司面板数据,从代理成本和公司绩效两个层面研究我国股权激励实施效果,结果表明:上市公司实施股权激励可抑制投资不足行为,却加剧了经理人的过度投资行为;股权激励计划并不能显著降低经理人的在职消费,由此而带来的以ROA衡量的公司绩效改善也并不显著,这从两个层面说明我国股权激励计划的激励效果并不明显. 相似文献

以沪、深两市非金融类A股上市公司2005~2009年的混合数据为研究对象,运用双变量回归(bivariate regression)、复回归(multiple regression)及协方差回归(ANACOVA)等计量方法,实证考察权益代理成本与公司价值间的关联性。研究结果表明,当权益代理成本降低时,我国上市公司的市场价值(托宾Q值)和财务业绩(ROA)均得到显著提高;且在引入内外部监督机制、管理层激励机制及股权结构特征三重约束后,二者的反向关联性仍维持稳定。此结论为代理成本理论增添了新的经验证据,即提升上市公司自身价值,保障投资者权益的有效途径之一就是降低代理成本。 相似文献

In this paper, the authors focus on the influence of corporate social responsibility (CSR) upon business profitability. In
order to be capable of working with homogeneous data, the authors’ starting point is to use the criteria defined by PricewaterhouseCoopers’
work on the subject, and published by the Spanish journal Actualidad Económica. In this work, an index was created which assigns between one and five points to the companies depending on the importance
given by them to CSR. The CSR measurement published by the Observatorio de la RSE will also be considered. In order to measure companies’ profitability, this paper will take into account their return on
equity (ROE) and return on assets (ROA) of 2005 and 2006. The authors’ purpose is to demonstrate that the relationship between
CSR and business profitability is neutral.

This paper investigates the way in which environmental responsibility impacts on corporate financial performance, measured by return on equity (ROE) and return on assets (ROA). Using a sample of Korean firms covering the period 2011–2012, and employing two different test methods, namely the OLS and 2SLS methods, we show that the relationships between environmental responsibility performance and firms’ ROE and ROA are positive and statistically significant. However, we show that research and development (R&D) intensity (expenditure) does not affect either environmental responsibility or corporate financial performance. The results of this analysis encourage further empirical analysis of the industries, as well as the use of more than one estimation method to determine environmental responsibility and corporate financial performance within firms.
