The oceans are the most extensive ecosystem on Earth,rich in ecological resources such as seawater and biological resources,as well as important ecosystem services such as carbon dioxide absorption,oxygen production and climate regulation. Discussing the basic logic,core mechanism and mode of value realization of marine ecological products will help to match different types of marine ecological products in coastal areas with corresponding value realization modes and operable experiences,which is of great theoretical significance and practical significance for realizing the ecological,economic and social benefits of marine ecological products and the sustainable use of marine resources. On the basis of sorting out the theoretical logic,institutional logic,technological logic,practical logic and their internal logical relationship for realizing the value of marine ecological products,and in accordance with the logical thinking of "resource element-product type-core mechanism-realization method-goal orientation",it is proposed that the core mechanism for realizing the value of marine ecological products,mainly including the value-added mechanism based on marine material supply products to meet the needs of human material life,the value compensation mechanism based on marine regulation service products to improve the human habitat environment,and the value creation mechanism based on marine cultural service products to meet the spiritual needs of human beings. Combined with domestic and international practice cases,the value realization modes of marine ecological products are mainly divided into 5 categories and 18 sub categories. The premium mode of marine ecological products includes marine brand value premium and marine intensive scale premium. The compensation mode of marine ecology includes marine protection and restoration,marine ecological compensation,marine transfer payment and marine damage compensation. The business development mode of marine ecological products mainly includes marine green aquaculture,marine green industry,marine ecotourism and marine ecological wellness. The trading mode of marine ecological resources rights and interests includes the trading of sea area use rights,marine emission rights,marine carbon sinks and marine water rights. The financing mode of marine ecological resources rights and interests includes marine green credit,marine green bonds,marine green funds and marine green insurance. In future practice and research,the value realization mode of marine ecological products should be further improved,establishing a professional trading platform for marine carbon sinks,standardizing marine ecological compensation standards,rationalizing the use and development of marine industries,improving the rules and regulations on the trading of interests in marine ecological resources,expanding the financing channels for interests in marine ecological resources,and strengthening the application of digital technology.
