As a form of enterprise organization with Chinese characteristic, mixed ownership is not only different from the classical private ownership enterprise in western countries, but different from the public ownership enterprise which is generally accepted by socialist countries. The mixed-ownership enterprise as a unique form of enterprise organization has been widely existed in the current practice of enterprise management in China, and has been popularized and supported. Considering of this, it is necessary to study the particularity of ownership structure of mixed-ownership enterprises, and the differences of the corporate governance mechanism which are led by it. This paper explores the integration of corporate governance of mixedownership enterprises with Chinese market economy and the improvement of countermeasures. By doing so, it hopes to provide some references for the study of socialist market economy with Chinese characteristics.
