内部控制与盈余管理方式选择

Internal Control and the Choice of Earnings Management Methods

选择2012年A股主板上市公司为研究对象,探讨内部控制与盈余管理之间的关系。基于GLM方差分析法和传统最小二乘法的检验表明,内部控制可以显著地抑制应计项盈余管理,却无法显著地抑制真实活动盈余管理;内控制质量越高,企业更倾向通过改变现金流支出和酌量性支出来进行真实活动盈余管理。在用2SLS方法校正内生性问题后,主要结论依然得到了支持。

This paper uses a sample of A-share listed companies to analyze the relationship between internal control and earnings management. Based on the methods of generalized linear model（ GLM） and ordinary least squares（ OLS）,it is found that better internal control can effectively restrict accrual earnings management but not real earnings management. Further study finds that as the quality of internal control increases,companies are more likely to engage in real earnings management by changing cash expenditure and discretionary expenditure. These results are robust after the 2SLS method is used to mitigate endogeneity.
