“…This area is not considered in this study and provides an empirical reference for this paper. In addition, this paper's cooperative versus non-cooperative game research method is a static mathematical model study that does not allow for dynamic trend analysis like the evolutionary game approach [ 62 ]. It does not allow for statistically significant results on large samples like the econometric approach [ 63 , 64 ].…”

“…Specifically, the overall efficiency of marine green aquaculture in China showed a slight upward trend, which is consistent with the above measurement results. Although China's mariculture green transformation started late with the promulgation of a series of policy documents supporting the green development of marine aquaculture fisheries, coastal provinces have accelerated the pace of mariculture green transformation, constantly improving the mechanisms and regulatory system of green mariculture [50,51] by increasing technological and human capital investments and promoting research into key technologies [52,53]. After a series of technological transformations and applications, the desirable output of marine green aquaculture has been significantly improved and the non-desirable outputs have been effectively reduced, which ultimately led to the increase in marine green aquaculture efficiency.…”

In-depth analyses of the spatial imbalance and polarization of marine green aquaculture efficiency have a profound impact on the realization of high-quality development of fisheries. Based on the data on mariculture in nine coastal provinces of China from 2006 to 2019, this research analyzed the spatial imbalance and polarization of green mariculture efficiency using quantitative measurements and explored their causes. The results showed that (1) the efficiency of marine green aquaculture in China is relatively effective, but there is still room for improvement. The spatial imbalance of the whole country and the three marine economic circles shows an increasing trend, and the efficiency of marine green aquaculture in China has two levels of differentiation characteristics. Compared with the coastal provinces with low and high levels of marine green aquaculture efficiency, the degree of spatial imbalance in the medium-level coastal provinces is greater. In the long run, the efficiency of China’s marine green aquaculture will slowly evolve to a high-level state, and it is particularly important to break the “self-locking trap” of the low-level state. (2) The differences in mariculture yield among coastal provinces are the main factor affecting the spatial imbalance of green mariculture efficiency in China. Promoting the development of low-carbon, resource-saving and high-added-value mariculture products and achieving a win–win situation of economic and ecological benefits is an important means to alleviate the spatial imbalance of China’s mariculture efficiency. (3) There is a certain polarization trend in the efficiency of marine green aquaculture in China, and the polarization degree shows an overall upward trend. Compared with the northern and eastern marine economic circles, the spatial polarization of green aquaculture efficiency in the southern marine economic circle is the lowest. During the observation year, the change in green aquaculture efficiency in coastal provinces did not converge into minority groups, and the main reason for spatial polarization was that there was a large gap in green aquaculture efficiency among coastal provinces. The research results can provide a reference for accelerating the green transformation of mariculture and promoting the high-quality development of fisheries.

“…Based on these studies, we concentrate on the supporting role of deep-blue fishery subsidies. Yu et al constructed an evolutionary game model of new pollutants in mariculture including government, sales platform and fishermen, and found that both government subsidies and penalties have positive effect in controlling new pollutants of mariculture, but there is a boundary of the role of the subsidy strategy (Yu et al, 2023b). He and Zhang constructed a tripartite evolutionary game model of fishery practitioners, research institutes and the government, found that subsidies will strengthen the willingness to participate in marine carbon sink fishery, while government control will frustrate their enthusiasm, and subsidies should be the main focus in the early stage of development, supplemented by penalties (He and Zhang, 2023).…”

IntroductionThe expansion of fishery development from offshore to deep-sea areas has become essential for countries to address environmental constraints and ensure food security. This study aims to establish a cooperative development model for deep-blue fishery involving the government, fishery enterprises, and consumers.MethodsWe constructed an evolutionary game and simulation model to analyze the government's deep-blue fishery subsidy strategy. The model considers the interactions between the government, fishery enterprises, and consumers, evaluating how different subsidy strategies influence the development of deep-blue fishery.ResultsOur results demonstrate that government subsidies can stimulate the growth of deep-blue fishery from both the demand and supply sides. Specifically, the likelihood of government subsidies positively affects fishery enterprises' engagement in deep-blue fishery development and consumers' willingness to purchase deep-blue fishery products. The evolutionary game system reaches different steady states based on the cost-benefit changes for the government, fishery enterprises, and consumers, leading to various optimal subsidy strategies.DiscussionThe findings indicate that the amount of government subsidy should be optimized rather than maximized, as excessive subsidies may not yield proportionate benefits. Additionally, subsidizing fishery enterprises proves to be more effective in promoting the development of deep-blue fishery compared to subsidizing consumers. These insights can guide policymakers in designing efficient subsidy strategies to foster sustainable deep-sea fishery development.
