“…Therefore, government blue carbon subsidy for marine ranching is a topic with theoretical significance and practical value. Wang et al [ 61 ] pointed out that the special subsidy for blue carbon in marine ranching can improve the motivation of marine ranching enterprises and blue carbon demand enterprises to trade blue carbon, which is the same as the findings of this paper. Zheng et al [ 11 ] proposed that subsidy is not the more, the better.…”

“…The comprehensive aquaculture of shellfish, algae, and marine pasture is also the process of the absorption, collection, storage, and buffering of CO 2 . It has the function of carbon sequestration and is an important part of the carbon cycle [8]. Therefore, in the marine aquaculture industry, the decoupling analysis of carbon emissions and economic growth should consider net carbon emissions instead of the traditional carbon emissions generated by human activities.…”

Decoupling Analysis of Net Carbon Emissions and Economic Growth of Marine Aquaculture

Decoupling carbon emissions from economic growth is the key for the sustainable development of developing countries. Based on the panel data of marine aquaculture in China from 2010 to 2019, this paper employs the Tapio decoupling index model to analyze the decoupling characteristics of net carbon emissions and the economic growth of marine aquaculture. The logarithmic average weight decomposition method (LMDI model) and Tapio decoupling effort index model are also introduced to explore the contribution of various areas, provinces, and factors to the decoupling of net carbon emissions and the economic growth of marine aquaculture. Empirical results show that: (1) Net carbon emissions have a decoupling trend from the economic growth of marine aquaculture, but there is a large regional difference. (2) Regarding the degree of decoupling efforts, it is much stronger in the eastern and southern ocean economic zones than that in the northern ocean economic zone. (3) In terms of the decoupling contributions of various factors, carbon emission intensity > aquaculture scale > aquaculture efficiency > aquaculture structure, but there is heterogeneity among the different regions. Among the reasons for the inter-regional differences, carbon emission intensity > aquaculture scale > aquaculture structure > aquaculture efficiency. A further redundancy efficiency analysis explains the source of the differences. On this basis, strategies are proposed to improve the efficiency of marine aquaculture, including the construction of a modern three-dimensional aquaculture system, the improvement of the market-oriented mechanism, and the establishment of a modern marine aquaculture economic system.

“…With a focus on the ecological environment, the composition and dynamics of bacterial and protist communities within Laoshan Bay Marine Ranch was investigated (Fang et al, 2021). Furthermore, certain studies have emphasized the significance of local governments offering specific subsidies for the blue carbon trading market in marine ranching (Wang et al, 2022). Marine ranches perform important ecological and economic functions, but also have various real problems and risks.…”

This study establishes a three-party evolutionary game model that includes marine ranch firms, consumers, and the government, with a focus on the digital transformation pattern of marine ranching. Subsequently, the researchers conduct gaming and simulation to analyze the government subsidy strategy in the digital transformation of marine ranching. The following findings are derived: (1) Government subsidies have the potential to facilitate the digital transformation of marine ranches, benefiting both the supply and demand sides. Government subsidies positively influence both the digital transformation of marine ranch firms and the involvement of consumers in this transformation process. (2) The findings from the evolutionary game system demonstrate that alterations in the cost–benefit dynamics of each participant lead to adjustments in the steady state, thereby prompting the government to adapt its optimal subsidy strategy. (3) More government subsidies are not always better. Excessive government subsidies will destroy the stability of the evolutionary game system, which is not conducive to the realization of the digitization of marine ranch. (4) Subsidizing consumers is more effective in driving the digital transformation of marine ranch than subsidizing marine ranch firms. Subsidies to marine ranch firms will destroy the stability of the evolutionary game system, whereas subsidizing consumers contributes positively to its stability.
