公司治理对上市商业银行盈余管理影响的研究
发布时间：2018-09-14 16:00
【摘要】：近几年来,我国证券资本市场发展迅速,上市公司往往会采取盈余管理行为来实现自己的一些目的,盈余管理也逐渐成为了会计学术界研究的热点。作为金融业支柱的上市银行,其经营安全性关系到宏观经济运行的稳定性,对其进行盈余管理研究显得尤为重要,而被普遍认为与盈余管理存在密切联系的公司治理结构,由于上市银行的经营特点常常被排除在盈余管理研究对象之外。公司治理结构本身作为两权分离的产物,对上市商业银行盈余管理影响如何?本文选取了2013年至2014年我国16家上市银行两年的数据样本为研究对象,采用规范研究和实证研究的方法,在理论分析时,大量阅读了前人的研究成果,萃取其营养,并在此基础上提出了本文的实证研究方法：首先根据盈余管理扩展的Jones模型对上市银行2013年和2014年的盈余管理进行估算,利用截面回归分析得出上市银行是否存在盈余管理行为的结论,接着提出六个假设,选取股权结构、董事会特征和审计质量这三个方面作为公司治理结构变量,并引入相关控制变量,进而建立本文的线性回归研究模型,运用相关软件进行描述性统计分析、相关性分析和多元回归分析,验证假设得出结论。研究结果表明：(1)我国上市银行普遍存在着盈余管理行为,且其盈余管理是负向的,即我国上市银行通过盈余管理调低其利润。(2)公司治理对上市银行的盈余管理有着十分重要的影响,其中：股权集中度越高,上市银行越有可能进行盈余管理：在董事会组成人员中,独立董事的比例越高,上市银行盈余管理程度越低,即我国上市公司实行的独立董事制度可以约束上市银行的盈余管理行为；股权制衡度、国有股持股比例、董事会规模、审计质量对上市银行盈余管理也有影响,但不显著。最后,据此提出了相应的对策建议。
[Abstract]:In recent years, with the rapid development of the securities capital market in China, listed companies often adopt earnings management to achieve their own goals, earnings management has gradually become a hot spot in accounting academia. As a pillar of the financial industry, listed banks' operating security is related to the stability of macroeconomic operation. It is particularly important to study earnings management, and it is generally considered that there is a close relationship between earnings management and corporate governance structure. The operating characteristics of listed banks are often excluded from the study of earnings management. How does corporate governance structure itself affect earnings management of listed commercial banks as the product of separation of two rights? This paper selects the data samples of 16 listed banks from 2013 to 2014 as the research object, adopts the method of normative research and empirical research, in the theoretical analysis, read a lot of previous research results, extract its nutrition. On this basis, the empirical research method of this paper is put forward: firstly, the earnings management of listed banks in 2013 and 2014 is estimated according to the extended Jones model of earnings management. By using cross-section regression analysis, the author draws the conclusion that there is earnings management behavior in listed banks, and then puts forward six hypotheses, including equity structure, board characteristics and audit quality as variables of corporate governance structure. Then the linear regression model of this paper is established by introducing the relevant control variables. The conclusion is obtained by using the related software to carry out descriptive statistical analysis, correlation analysis and multivariate regression analysis. The results show that: (1) earnings management is common in listed banks in China, and its earnings management is negative. That is, the listed banks in China lower their profits through earnings management. (2) Corporate governance has a very important impact on earnings management of listed banks. The more likely listed banks are to carry out earnings management: the higher the proportion of independent directors is, the lower the earnings management degree of listed banks is. That is, the independent director system of listed companies in our country can restrain the earnings management behavior of listed banks; the degree of equity balance, the proportion of state-owned shares, the size of board of directors and the quality of audit also have an effect on earnings management of listed banks, but they are not significant. Finally, the corresponding countermeasures and suggestions are put forward.
