| Summary: | 碩士 === 國立東華大學 === 企業管理學系 === 91 === The explosion of the financial scandal in the U.S. has impacted the confidence of global investor again since the financial crisis in Asia, and the untrue financial statement is the main reason. Therefore it becomes more important to enforce the enterprise transparency and to reduce the possibilities of the earning manipulation in a corporate.
We are considering that if the higher degree of the corporate disclosure will reduce the possibilities of the earning manipulation, since there are less information asymmetry between the investors and the corporate manager. Besides this, in order to control the variable that would probably affect the discretionary accruals, we put Asset, Leverage, and Operational Cash Flows in the regression. We focus on 212 electronic companies that have gone public in TSE in 23, April 2003, and make use of four kinds of commonly used discretionary accruals to judge the model to detect the earning management in the sample companies. Then we use Mann-Whitney U test, t test, and multiple regression function to do the statistical analysis.
The empirical result shows that, only Jones and Modified Jones Model support the hypothesis that the highly degree of corporate disclosure will reduce the range of earning management. As to the size hypothesis and the debt covenant hypothesis, we are not able to get conclusion.
