【摘要】：随着一系列财务舞弊案的发生，投资者开始不信任上市公司披露的内部控制信息，严重影响到资本市场的发展和投资者的信息需求。2002年，美国国会颁步《萨班斯一奥克斯利法案》,要求上市公司强制披露公司的内部控制信息。其后，我国也颁布了一些法规，但上市公司总体披露情况不够理想。到底是什么因素影响内部控制信息披露呢？如何提高内部控制信息披露程度呢？这些问题无不引起投资者、科研人员和监管者等人的关注。此文以创业板2010年上市公司作为研究样本，其上市公司存在着市盈率高、高管频频离职、高管减持公司股票等问题，结合内部控制、审计委员会、股权结构和审计机构等因素进行原因和对策分析，进而在创业板上市公司这个背景下，从审计委员会、控股股东持股比例和审计机构权威性这三方面分析影响内部控制信息披露的因素和提高内部控制信息披露程度。本文在参考国内外研究文献的基础上，首先对公司治理和内部控制信息披露之间相关概念和理论基础进行了分析，并分析了二者之间的相关性，，同时强调了内部控制信息披露的重要性，为后文的研究打下理论基础。其次，运用2010年创业板上市公司的年报数据，选取是否设立审计委员会和控股股东持股比例作为内部治理结构变量，选取审机构权威性作为外部治理机制变量，从公司治理角度即内部治理结构和外部治理机制两方面出发，以内部控制信息披露作为被解释变量，以是否设立审计委员会、控股股东持股比例和审计机构权威性作为解释变量，提出假设，建立多元线性回归模型，运用Eviews3.1，采用异方差分析、多重共线性分析、描述性统计分析、相关性分析、回归分析、协方差分析进行了实证研究，实证研究结果表明：是否设立审计委员会和审计机构权威性与内部控制信息披露呈正相关关系，控股股东持股比例与内部控制信息披露负相关。强化审计机构的制度和职能建设，以保证审计委员会更好履行自身的职责；培育大量机构投资者，减少大股东持股比例，增发社会公众股，不断吸引多元投资者进行投资，不断优化公司股权结构；通过加强注册会计师执业水平和职业道德的建设，提高注册会计师审计的独立性，加强注册会计师对内部控制信息披露的审核力度，提高内部控制信息披露质量等。
[Abstract]:With the occurrence of a series of financial fraud cases, investors began to distrust the internal control information disclosed by listed companies, which seriously affected the development of the capital market and the information needs of investors. 2002. The United States Congress passed "Sarbanes-Oxley Act", requiring listed companies to disclose the information of internal control of the company. After that, China also issued some laws and regulations. But the overall disclosure of listed companies is not ideal. What factors affect the disclosure of internal control information? How to improve the degree of internal control information disclosure? These problems have attracted the attention of investors, researchers and regulators. In this paper, the gem listed companies in 2010 as a research sample, its listed companies have high price-earnings ratio, executives frequently quit. Combined with internal control, audit committee, equity structure and audit institutions, the reasons and countermeasures are analyzed, and then under the background of gem listed companies, the audit committee. This paper analyzes the factors that affect the disclosure of internal control information and improves the degree of disclosure of internal control information from the three aspects of controlling shareholder's shareholding ratio and audit institution's authority. Based on the domestic and foreign research literature, this paper first analyzes the related concepts and theoretical basis between corporate governance and internal control information disclosure, and analyzes the correlation between the two. At the same time, it emphasizes the importance of internal control information disclosure, which lays a theoretical foundation for the later research. Secondly, it uses the annual report data of gem listed companies in 2010. Choose whether to set up audit committee and the proportion of controlling shareholders as internal governance structure variables, select the authority of the audit body as the external governance mechanism variables. From the perspective of corporate governance, that is, the internal governance structure and the external governance mechanism, the internal control information disclosure is taken as the explained variable to establish the audit committee. Holding ratio of controlling shareholders and authority of audit institution are taken as explanatory variables, hypothesis is put forward, multivariate linear regression model is established, Eviews3.1, heteroscedasticity analysis and multiple collinear analysis are used. Descriptive statistical analysis, correlation analysis, regression analysis, covariance analysis conducted empirical research. The empirical results show that the establishment of audit committee and the authority of audit institutions are positively correlated with the disclosure of internal control information, and the proportion of controlling shareholders is negatively correlated with the disclosure of internal control information. Strengthen the system and function of audit institutions to ensure that the audit committee performs its duties better; Cultivate a large number of institutional investors, reduce the proportion of major shareholders, issue additional public shares, attract multiple investors to invest, and constantly optimize the company's equity structure; By strengthening the level of CPA practice and the construction of professional ethics, improve the independence of CPA audit, strengthen the CPA audit of internal control information disclosure. Improve the quality of internal control information disclosure.
