Eco-product value realization and eco-industry are in a rapid development stage, but the eco-product value realization mechanism is still unclear. Strengthening research on eco-industry and eco-product value realization not only helps to coordinate the relationship between regional ecologies and the economy but also contributes to regional sustainable development. This study conducted a systematic literature review based on related articles retrieved from the Web of Science database and China National Knowledge Infrastructure database. The results showed the following: (1) Regarding time series, the average annual number of published works in the literature from 2000 to 2017 is less than 4, while the average annual number of published works in the literature from 2018 to 2022 is more than 97. The overall study on eco-product value realization and eco-industry has shown a year-on-year growth trend. (2) The research content primarily involves five aspects, including the connotation and extension of eco-products, eco-product supply, eco-product value accounting, eco-product value realization, and eco-industry. (3) It is essential to deepen the study on the improvement mechanism of the eco-product supply capacity, eco-products property rights, evaluation system for eco-product value realization, ecological compensation mechanism, driving mechanism for eco-products to eco-industry, and coupled development of ecological restoration and eco-industry. Based on the above research, this paper presents an enlightment of the forest ecosystem services in the karst ecological restoration area from three aspects: enhancing the supply ability of eco-products, improving the compensation mechanism of forest ecological services, and coordinating the development of ecosystem services and eco-industries.

The achievement of eco-product value and the growth of eco-industry can boost the economic advancement of karst areas. The findings of a statistical analysis of 520 relevant studies reveal the following: (1) From a time series perspective, the amount of papers increase with each wave of research; (2) contents mainly concentrate on four aspects, namely, ecosystem services supply (8.46%), value accounting (10.58%), value realization (37.88%), and eco-industry (30.38%); (3) the study areas are primarily concentrated in Asia (85.96%), Europe (7.12%), and North America (4.04%), most of which are located in China’s karst areas with vulnerable ecological environments and regions that are aware of eco-product values; and (4) research frontiers are reflected through four aspects of the ecosystem, namely, services supply, value accounting, value realization, and the eco-industry. Based on the analysis in this paper, it can be concluded that paths, mechanisms, and models for eco-product value realization are still slow. Therefore, to support the growth of karst agroforestry ecosystem services, it is imperative to further research the capacity of agroforestry ecosystem services supply, value accounting systems, ecological compensation mechanisms, the value realization models of eco-products, and the formation mechanism of eco-industries.
