内部控制审计、内部控制缺陷与真实盈余管理——来自中国A股市场的证据

Internal control auditing,internal control deficiency and real earnings management

从公司内外部治理机制联动视角入手,以中国A股上市公司为数据样本,考察内部控制审计、内部控制缺陷对上市公司真实盈余管理行为产生的影响。研究表明,内部控制审计自愿阶段,进行内部控制审计的公司真实盈余管理程度较低;但相对于内部控制建设较好的公司,内部控制存在缺陷的公司其内部控制审计对真实盈余管理行为的影响大大减弱。内部控制审计进入强制阶段后,上市公司的真实盈余管理程度有所降低。内部控制无论是存在财务报告方面的缺陷还是非财务报告方面的缺陷,都会弱化内部控制审计对真实盈余管理行为的外部治理作用,这充分表明我国基于审计视角和管理视角的内部控制披露具有更加丰富的信息含量。

This paper explores the impact of internal control auditing and internal control deficiency on real earnings management by analyzing the data of A-share listed companies in China from the perspective of external and internal governance. We have the following results. Companies with disclosure of internal control auditing report have lower real earnings management during the voluntary phase; however, internal control deficiency weakens the effect of internal control auditing on real earnings management. Compared with the voluntary phase,real earnings management is even lower in mandatory phase. Deficiency in both financial reporting and non-financial reporting can weaken the effect of internal control auditing on real earnings management,which indicates that China internal control disclosure based on auditing and management has more information content. Our study reveals that compared with internal control as an internal governance mechanism,internal control auditingstill has a certain lag though it can prevent the occurrence of real earnings management to a certain extent,and that when only the internal and external governance mechanism work together can corporate governance be improved.
