Based on the theory of earnings management, contract and corporate governance, the hypothesis of the motivation of accounting errors is proposed including eight variables, such as ratio of earnings increasing, leverage, scale of the company and independent auditing etc, and two control variables. Through the statistics of the magnitude of accounting errors, there comes the result that not only the amount but also the magnitude of errors of companies who made overstatement errors is much more than those made understatement errors. Through one by one matching between research samples and controlled samples, mean value test, signed-rank test and Logistic regression, it uncovers that overstatement errors he distinct motivation of earnings management. Those companies more likely to make overstatement errors are characterized by loss in the year, limited scale, higher leverage etc. At last, the paper puts forward several suggests about how to prevent the listed company from making accounting error correction to conduct earnings management.
