【摘要】：现代企业是契约管理模式，股东作为出资人是委托人，管理者是代理人对企业的事项进行经营决策，对委托人承担责任，其经营决策直接影响委托人的经济利益。而外部信息使用者和企业内部之间信息不对称的现象，为经营者提供了隐秘空间。经营者为谋取短期利益，对企业财务报表进行调整或者进行虚假交易操作，直接影响股东的长期利益，导致信息质量下降。如何提高企业信息披露质量，抑制上市公司盈余管理操作，成为重中之重。近年来，我国在内部控制制度方面做出巨大努力，2010年颁布了《企业内部控制应用指南第1号——组织框架》等规范，内部控制制度的完善可以在一定程度上规范管理者的行为，上市公司整体的信息披露质量也有所提高，但是制度之下企业仍有各种规避手段，一些企业信息披露质量仍不容乐观。因此，研究内部控制质量对企业盈余管理程度的影响的重要性，并且分析内部控制质量对哪一种盈余管理具有作用效果，并提出相应的政策措施是目前亟待解决的问题。本文以2011年沪深两市主板的1616家上市公司作为研究对象，采用是否自愿披露内部控制鉴证报告、是否披露合理保证的内部控制鉴证报告作为被解释变量、采用琼斯模型计量的会计选择盈余管理、真实活动盈余管理（操纵性现金流量、操纵性生产成本、操纵性酌量费用）作为被解释变量，采用经营周期、企业规模、每股收益等作为控制变量，，构建内部控制质量与盈余管理相关关系的回归模型。运用EXCEL和SPSS17.0软件，对样本数据进行描述性分析、共线性分析、回归分析，最后得出结论是内部控制质量与会计选择盈余管理程度具有负相关关系，对真实活动盈余管理不具有相关性。根据实证结论，分析原因，主要是内部控制制度不够完善。虽然内部控制质量提高对会计选择盈余管理有较好抑制作用，但其不能及时地规避企业的账外操作，使得真实活动盈余管理有可操作空间，具有较强的隐秘性。因此提出建立外部监督体系、完善财经法律法规、完善企业内部控制制度、优化董事会结构和规模、加速经营周期提高企业流动性、完善薪酬管理制度等政策建议。
[Abstract]:The modern enterprise is the contract management mode, the shareholder as the investor is the principal, the manager is the agent carries on the management decision to the enterprise affairs, undertakes the responsibility to the trustor, its management decision directly affects the trustor's economic benefit. The phenomenon of information asymmetry between external information users and enterprises provides hidden space for operators. In order to obtain short-term benefits, operators adjust financial statements or conduct false transactions, which directly affect the long-term interests of shareholders and lead to a decline in the quality of information. How to improve the quality of information disclosure and restrain the earnings management of listed companies has become the top priority. In recent years, China has made great efforts in the field of internal control system. In 2010, it promulgated the guidelines for the Application of Enterprise Internal Control No. 1-organizational Framework, etc. The perfection of internal control system can standardize the behavior of managers to a certain extent. The quality of information disclosure of listed companies has also been improved, but under the system, enterprises still have a variety of evasive means, some enterprises are still not optimistic about the quality of information disclosure. Therefore, it is important to study the influence of internal control quality on the degree of earnings management, to analyze which kind of earnings management the internal control quality has the effect, and to put forward the corresponding policy measures are the problems to be solved. This paper takes 1616 listed companies on the main board of Shanghai and Shenzhen Stock Exchange in 2011 as the research object, and adopts whether to voluntarily disclose the internal control authentication report and whether to disclose the reasonable assurance internal control authentication report as the explained variable. Accounting choice earnings management based on Jones model, real activity earnings management (manipulative cash flow, manipulative production cost, manipulative discretionary cost) are used as explanatory variables. As control variables, earnings per share (EPS) are used to build a regression model of the relationship between internal control quality and earnings management. By using EXCEL and SPSS17.0 software, the sample data are analyzed by descriptive analysis, linear analysis and regression analysis. It is concluded that the quality of internal control has a negative correlation with the degree of earnings management in accounting selection. It is not relevant to the earnings management of real activities. According to the empirical conclusion, the main reason is that the internal control system is not perfect. Although the improvement of internal control quality can restrain the accounting choice of earnings management, it can not avoid the off-account operation of the enterprise in time, which makes the real earnings management have operational space and strong secrecy. Therefore, the paper puts forward some policy suggestions, such as establishing external supervision system, perfecting financial laws and regulations, perfecting internal control system of enterprises, optimizing the structure and scale of board of directors, speeding up the operation cycle, improving the liquidity of enterprises, perfecting the salary management system, and so on.
