Ecological value realization of blue carbon in marine ranching is essential to achieve carbon neutrality. The motivation for conducting the study is to verify whether multi-agent cooperation can promote the ecological value realization of blue carbon in marine ranching. Based on the blue carbon ecological value realization model of marine ranching enterprises, blue carbon demand enterprises, blue carbon trading platforms and government, this paper explores the cooperative governance strategy of marine ranching for each subject using cooperative game and non-cooperative game models. Further, we conduct a comparative analysis to arrive at the optimal strategy. The conclusions are as follows. Multi-agent cooperation is more conducive to the ecological value realization of blue carbon in marine ranching. Compared with non-cooperative governance, the platform's commission and blue carbon price are lower, and the blue carbon output, profit of each market subject, government utility and overall profit are higher in cooperative governance. The strengths of this paper lie in 2 aspects. First, we focuses on the ecological value of blue carbon in marine ranching instead of economic value, providing a new theoretical basis for ecological compensation in marine ranching. Second, we construct a government-led and market-oriented operation of marine ranching's blue carbon ecological value realization mechanism, incorporating blue carbon trading platform and government into the value realization model.
海洋牧场中蓝碳生态价值实现对于实现碳中和至关重要。开展本研究的动机是验证多主体合作能否促进海洋牧场中蓝碳生态价值的实现。基于海洋牧场企业、蓝碳需求企业、蓝碳交易平台和政府的蓝碳生态价值实现模型，本文运用合作博弈和非合作博弈模型探索各主体对海洋牧场的协同治理策略。进一步地，我们进行比较分析以得出最优策略。研究结论如下。多主体合作更有利于海洋牧场中蓝碳生态价值的实现。与非协同治理相比，协同治理中平台佣金和蓝碳价格更低，蓝碳产量、各市场主体利润、政府效用及总利润更高。本文的优势体现在两个方面。其一，我们关注的是海洋牧场中蓝碳的生态价值而非经济价值，为海洋牧场生态补偿提供了新的理论依据。其二，我们构建了以政府为主导、市场为导向的海洋牧场蓝碳生态价值实现机制运行模式，将蓝碳交易平台和政府纳入价值实现模型。
