After the Sarbanes-Oxley Act researchers found company's management transfered the previous accruals earnings management to a more imperceptible real earnings management. In the study, I chose the listed company between years 2007 and 2013 as the research samples, While referring to the research structure of Roychowdhury (2006), using the abnormal operating cash flow, abnormal production costs and abnormal discretionary expenses to proxy the real earning management. And discussion of the relevance between audit committee establishment and real earning management and are the audit committee characteristies have the inhibitory effect to the enterprise execute real earning management or not.
The empirical results show, companies that established an audit committee will not execute the real earning management of abnormal production costs and abnormal discretionary expenses, but the abnormal operating cash flow does not have significantly effect. The more independent of the audit committee, the less a company will manipulate the operating cash flow; the more professional of the audit committee, the less a company will manipulate the production costs. And the audit committee members that serve a number of companies would not manipulate production costs, but there are more real earnings management in other respects, which is consistent with research thesis, more concurrently positions lower the supervision function. The study will help the stakeholders to judge a company’s real earning management by the establishment and characteristics of audit committee.
