Value realization of ecological products is a vital mechanism to correct environmental externality and to protect ecosystem function and integrity. Based on scientific literature and pilot cases, narrow and broad concepts of ecological products are herein defined. In view of the importance of capital adequacy for pilot projects, ecological product value realization models were divided into public pays, NGO pays, government pays, and multi-pays according to the source of funding. In addition, a comparative analysis was carried out on the characteristics, application fields, advantages, and limitations of the models, which provides technical support for raising funds and for implementing the beneficiary pays principle. According to the analysis framework, we analyzed the realization mechanisms and paths of the ecological products of the pilot cases. We put forward the following suggestions to improve capital efficiency and ecological benefits:choose suitable policy instruments, set adequate monitoring indicators, and strengthen performance evaluation.
