To encourage continuous improvement of corporate governance and enhance market confidence, the Taiwan Stock Exchange began to implement the Corporate Governance Evaluation System in 2014, and announced the evaluation results for the first time in 2015.This study examines whether the implementation of the evaluation system reduce companies’ earnings management behavior by studying the association between the evaluation results and the extent of earnings management. Furthermore, this paper also investigates whether the announcement of the evaluation results have any impact on a company’s share price. The empirical results show that companies reduced their earnings management behavior after the implementation of the evaluation system. Furthermore, after the implementation, firms with better evaluation results show lower levels of earnings management. In addition, firms with better evaluation results show higher abnormal stock returns when the results were released.
