The cultural service value realization of ecological products builds a bridge between ecosystems and human well-being and it is an important part of the exploration of the value realization mechanism of ecological products in national parks. In order to promote the transformation of lucid waters and lush mountains in national parks to invaluable assets and better meet people's growing demand for high-quality cultural ecosystem services, this paper proposed the path and mechanism of realizing the value of cultural service of ecological products in national parks (CSEPNPs) on the condition of the identification of functional characteristics and realization conditions. The analysis followed the chain process of "function-product/services-benefit-value" of ecosystem services based on the framework of ecosystem services cascade. We found that the path of realizing the value of CSEPNP includes six steps, namely clear ownership, survey and monitoring, product production, value accounting, project operation and trading. It was suggested to improve and optimize the mechanism on realizing the value of CSEPNP from policy, ecological compensation, investment, franchising, technology application, and public participation. In view of the characteristics of joint production of cultural ecosystem services and strong dependence on social construction, the value realization mechanism proposed in this paper from the perspective of stakeholders was conducive to improving and optimizing the humanistic feedback of the cascade framework in theory, and promoting the supply and demand matching between ecological products and cultural services in national parks in practice. With the continuing study on supply-side theory, method and policy, future research should pay attention to demand-side investigation, monitoring, evaluation methods and public participation and supervision mechanism research, so as to achieve real-time matching of supply and demand.

As an important bridge connecting the natural ecosystem and human society, the improvement of the value realization efficiency of forest ecological products significantly impacts the realization of sustainable development goals. This paper aimed to explore how the new quality productive forces can empower the value realization efficiency of forest ecological products and promote the sustainable and efficient utilization of forest resources. Based on the dynamic qualitative comparative analysis method, using the panel data of 30 provinces (autonomous regions and municipalities) from 2011 to 2022, this paper analyzed the multi-factor synergistic linkage effect of new quality productive forces in the process of improving the value realization efficiency of forest ecological products. The study found that: (1) A single factor couldn't constitute a necessary condition for the high value realization efficiency of forest ecological products, but the necessity of innovative productivity, technological productivity, resource productivity, environmental productivity, digital industry productivity and industrial digital productivity was gradually increasing. (2) The high value realization efficiency of forest ecological products had four driving paths: "innovation+environment", "technology+environment+industrial digit", "resources +digit" and "innovation+resources". The low value realization efficiency of forest ecological products had three restrictive paths: "green+industrial digit", "technology+green" and "innovation+environment". (3) All the four driving paths of high value realization efficiency of forest ecological products had spatial heterogeneity, and the "innovation+environment" driving path has significant time effect. The research results provided not only theoretical support for understanding the empowering effect of new quality productive forces on the value realization efficiency of forest ecological products, but also practical guidance for optimizing the management of forest ecological products and enhancing the value of ecological services.
