Therefore, the new accounting standards on the prudence principle done adjust, mainly displays in: introduction of the fair value, depreciation, intangible assets , investment real estate, other transactions or events in the prudence principle of moderate applications such as debt restructuring, donation, etc. Based on listed companies in Shenzhen and Shanghai stock exchange as a research sample in 2005——2007, using descriptive statistics, Pearson correlation and regression analysis of model, this paper tests the existence and the changes of accounting conservati at the new GAS before and after implementation from the timeliness and sustainability of earns. Draw the following main conclusions: Firstly, the whole listed companies of 2005 had the characteristics of accounting conservati. And after eliminated or controlled loss-making companies, the characteristics of accounting conservati has nearly disappeared, this also shows that the quality of accounting information for loss companies was more bad. Secondly, after the new GAS promulgated, accounting conservati of the whole listed company appeared inflection point in 2006.
