以我国上市公司A股2007—2012年的数据,对上市公司的盈余管理行为与外部审计之间的关系进行实证研究。结果显示:上市公司被出具“非标意见”的概率与其应计盈余管理的程度显著正相关,与其真实盈余管理的程度相关不显著。相比本土会计师事务所,由国际四大会计事务所审计的上市公司真实盈余管理程度显著更低。表明相比真实盈余管理行为,外部审计对应计盈余管理行为的治理作用更为显著;而对于更为隐蔽的真实盈余管理行为,国际四大会计事务所发挥了更为显著的治理作用。
Based on the data of A shares of listed companies in China from 2007 to 2012, this paper conducts empirical research on the relationship between earnings management behavior of listed companies and external auditing. The result shows that the probability that the listed company is issued “non-standard opinion ” is significantly and positively correlated with the degree of its accrued earnings management, but not significant with the degree of its real earnings management. Compared with local accounting firms, the real earnings management of listed companies audited by the top four accounting firms is significantly lower. It shows that the external auditing plays a more significant role in the governance of earnings-accruals than in the real earnings management practices. For the more subtle real earnings management practices, the four major international accounting firms play a more significant role in governance.
