中文摘要：

会计准则规范会计信息，而会计信息通过定价机制和治理机制实现对投资者的保护。我国会计准则自1992年首次发布以来，会计稳健性的规定不断变迁，先后呈现出侧重保护外商投资者、国有出资人和市场投资者的趋势。但是由于市场经济环境不完善、配套制度不健全等因素，我国会计准则的稳健性并没有完全体现在会计实务中，其投资者保护机制只得到了部分实现。

英文摘要：

Accounting standards regulate accounting information, while accounting information pro- tects investors via the pricing mechanism and governance mechanism. The regulations on accounting conservatism have experienced many changes since the first release of China＇ s accounting standards in 1992. There have been such trends as placing extra emphasis on the protection of the foreign investors, the state-owned investors and the market investors, one after another. However, due to imperfeet market economic surroundings and defective supporting regulation systems, the accounting conservatism of China＇ s Accounting Standards has not been fully put into the accounting practice, and thus its mechanism of investor protection has only been partially achieved.
