Starting from analyzing the use of goods, this paper discussed the Non-excludability and Non-rivalry characteristics of the goods in four assumed occasions based on different using methods and directions among users. It holds that Non-excludability and Non-rivalry are neither the objective attribute of goods, nor the result of public decision-making and public supply, but come from a special use situation among users. On this basis, a two-stage “provision-exclusivity” game model was established to analyze the The evolution and degradation of private property rights with relative prices and population size when goods exhibit non-exclusive feature in a natural state. Finally,the possibility conditions of spontaneous development of property right system under various frequency components are given.
