The quality of listed companies' accounting information has always been highly valued by investors, creditors and government authorities. As the core part of accounting information, earning information seems more important. On February 15, 2006, the Ministry of Finance in China issued 39 new enterprise accounting standards (including 1 basic standard and 38 particular standards), and from January 1, 2007, new accounting standards were firstly executed in listed companies. Comparing with old accounting standards, the new one has changed greatly so as to restrict listed companies'profit manipulation, and build a favorable atmosphere for listed companies'earnings quality evaluation. Until now, accounting standards have been executed for more than one year, what effects have been brought about by new accounting standards, and whether new accounting standards have enhanced listed companies'earnings quality or not, the thesis answered the above questions after in-depth research.The research of this thesis is mainly divided into five parts,the structure of the thesis is arranged as follows:In the first part, it analyzed the research background and significance. Then it reviewed related literatures on earnings quality evaluation so as to ascertain the thesis'contents and ideas. At last, it pointed out research methods.The second part of this thesis is the theory foundation. In this part, it firstly difined earnings quality, then pointed out the research of this thesis is according to Qualitative Characteristics Theory of earnings and the research perspective is Decision-Useful Perspective.The third part firstly choosed 15 indexes according to Qualitative Characteristics Theory of earnings information, and filtrated 8 indexes through Cluster Analysis Method and Selecting Typical Indexes Method. Then it made use of the 8 indexes to construct the evaluation model by Factor Analysis Method, which can be uses to evaluate listed companies'earnings quality.The fourth part and the fifth part are the core of the thesis. These parts did empirical study on listed companies'earnings quality before and after the implementation of new accounting standards, and analysed the outcomes from several aspects, especially combined with new accounting standards to analyse. Through analyzing we can see, that listed companies'earnings quality had no acute changes before and after the implementation of new accounting standards, and it is because that new accounting standards have been only executed for a short time, we should observe the implementation effects of new accounting standards in a longer time.In the final part, aiming at the current problems of listed companies'earnings quality,which were found in empirical research, this thesis put forward some relevant suggestions, then it advanced the limitation of this article, which needed further study.
