Abstract: Establishing the basic economic system is an important achievement for property rights system reform， and promoting the microscopic construction of modern socialist property rights with Chinese characteristics is the key to deepening the current property rights system reform， which is also helpful to perfect the basic economic system. The property rights system reform at this stage is closely related to the innovation and development of Marxist property rights theory， which calls for the theoretical foundation of Marxs thoughts of property rights socialization. Thus， it is of great significance to construct the pluralistic and diverse capital competition structure led by public capital as well as the corresponding capital management and supervision system， to set up the concepts of property rights that reflect the needs of property rights socialization and the property principle of “one right to one owner”， and to explore and establish the models of joint-stock enterprises which suit property rights socialization with Chinese characteristics.

Key words: property rights system reform, Karl Marx, thought of property rights socialization
