Based on the requirement of effective protection of the property interests of eco-products(EPs) suppliers,the property rights approach to the property interests of Eps suppliers is explored separately in terms of both external and internal typification by using the concept of ecological property rights.The study concludes that Property Rights of EPs are the property rights of supplier to the supplied EPs,and are a structural extension of the property rights of natural resources as well as a supplement to the mechanisms of ecological compensation and ecological product value realization,and have a solid theoretical,institutional and practical foundation.On the basis of this external typification,it should follow the logic of evolution of rights,take the demand for EPs supply,the support of boundary division technology and the change of interest structure as the limit,expand the types of Property Rights of EPs from both single and overall aspects,clarify the rights of suppliers to use,profit from and dispose of EPs,and realize its intrinsic and substantial typological construction.At the same time,the system of registration and certification,offset and transfer of eco-products should be improved to provide key institutional guarantee for the generation and realization of ecological property rights.
