Abstract: Marx’s application of the word “Eigentum” embodies two layers.Ownership means the major content with “totality” and “practice” as two basic features.Among them,ownership indicates that the owners regard the production materials as their own.And totality means that the individual owning of production materials are realized in specific social system.Practice suggests that the individual owning of production materials is a dynamic process of materials production.For private property,the content of ownership evolved into a comparative module between “ownership” and “property”.Ownership at national level symbolizes the universal rights bestowed to citizens and property has become abstract materials owned by individuals in the process of production.

Key words: ownership, own, totality, practice
