【摘要】 旨在惩罚财务舞弊的美国萨班斯法案对认知性盈余管理(CEM)的消除效果已得到验证。为了检验作为中国版萨班斯法案的内部控制规范体系在颁布后是否抑制了CEM,本文采用Benford定律分析了1990至2014年间净利润为正的全部A股上市公司盈余数据。研究发现,CEM在内控规范体系颁布前广泛存在,但是内控规范体系颁布后CEM在整体上并未明显消除;CEM在内控规范体系颁布后的自愿实施阶段依然存在,但在强制实施公布的当年得到了消除,而在强制实施公布后两年又出现反弹。研究还发现,CEM并没有因较高的内部控制质量而得到完全抑制。这表明,与美国萨班斯法案的实施效果不同,我国企业内控规范体系对CEM的抑制效果呈现阶段性和时效性特征,应该提升内控规范体系的法律地位和强制执行力并明确规定严惩措施,同时审计机构在出具审计意见时也应该重点关注企业CEM。更多还原

【Abstract】 The effect of Sarbanes-Oxley Act,which was enacted to punish financial frauds,on eliminating the Cosmetic Earnings Management(CEM) has already been testified.In order to test whether the enforcement of Chinese version of Sarbanes-Oxley Act inhibits the CEM,this paper employs Benfords Law to analyze the data of the China s A-share listed companies whose net profit were positive during the year of 1990 to 2013.The results reveal clear signs of CEM in China prior to this legislation and on the whole it was not inhibited afterwards.Further,CEM still existed during the voluntary implementation phase after legislation,but was eliminated in the year that the Internal Control Standard System in China was announced to be enforced though one year later CEM rebounded again.The results also show that CEM is not totally inhibited by higher Internal Control quality.It is suggested that the effect of Internal Control Standard System in China on inhibiting CEM shows some periodicity and timeliness characteristics which are different from those of the implementation effect of Sarbanes-Oxley Act.The implications are the legal status and enforcement of Internal Control Standard System should be enhanced,the punitive measures should be specified clearly and audit opinions issued by the audit institutions should also focus on CEM.更多还原
