“…Yuan et al (2023), Krabbe et al (2022), and identified several factors that influence the carbon sink capacity of the marine fishery, including national policies, fishing output, number of employees, area of shellfish and large-scale seaweed aquaculture farms, total power of fishing vessels, and reform of international fishery law. In addition, Zhang et al (2023a) and Li et al (2023c) argued that collaborative efforts among multiple stakeholders and financial support are more advantageous in realizing the ecological value of blue carbon in marine ranches, whereas Alsaleh et al (2023) discovered that the utilization of fossil fuels serves as a crucial driving force behind the degradation of carbon sinks. Research on carbon emissions in marine fishery is also a hot topic.…”

Marine fishery, with its duality of carbon emission and carbon sink, is an industry that needs full attention during achieving carbon neutrality. In this paper, the decoupling index between net CO2 emissions and gross domestic product of marine fishery in China is calculated using Tapio model, and its evolution characteristics are analyzed by means of nuclear density map and Markov matrix. Some problems are found, such as the decoupling state lacked significant improvement during this period and was unstable. Through theoretical analysis, this paper puts forward the view that solving these problems requires support from green finance. Then, this paper selects panel data from 11 coastal provinces and cities in China from 2010 to 2020 and uses the Logit model and EKC model to investigate the impact of green finance on the carbon decoupling state of marine fishery. The main results of this study are as follows: 1) Green finance can increase the odds ratio of strong or weak decoupling in marine fishery. This effect is more significant in regions with a high degree of digital finance development and the eastern marine economic circle. The effect of green investment is more significant than green insurance. In addition, boosting technological innovation and reducing the proportion of coal consumption can strengthen this effect. 2) The EKC curve between net CO2 emissions and gross domestic product of marine fishery is N-shape, which has a deterioration point. Green finance can delay the arrival of the deterioration point, meaning it can prevent the rapid deterioration of the decoupling state with the development of marine fishery. This paper provides empirical evidence and decision-making reference for resolving the dilemma of carbon decoupling in China’s marine fishery.

“…At present, the relevant research studies on marine pasture in China are gradually becoming mature, from the hard environment to the soft environment, from the site selection of marine pasture [12,13], properties of algal reef materials [14,15], and spatial layout [16,17] to modern marine pasture construction [15], ecological security assessment [18][19][20], and research on the key technologies of marine pasture [21,22]; from the emphasis on economic benefits to the consideration of both economic and ecological benefits, the analysis of potential economic benefits [23,24] to ecological benefits [25,26], and the measurement of comprehensive benefits [27,28]. In recent years, with the "two mountains theory" and the "two-carbon target" successively proposed, the academic community has focused on topics such as carbon sinks in marine pastures and fisheries [29,30], most scholars have measured the blue carbon sink with marine shellfish and algae as objects [31,32], and some scholars have also started from carbon sink pricing and incentive subsidies [33,34].…”

Under the double pressures of economic growth and ecological environment protection, sea green transformation and the sustainable development of mariculture are critical. This paper constructs an evolutionary game model with the government as the main body and mariculture farmers (enterprises) as the main body and puts forward the research hypothesis. Based on 2006–2019 longitudinal data of nine provinces along China’s coast, using multi-period Difference-in-Difference (DID) and dual robust estimation, we empirically investigate the national oceanic ranch demonstration zones for the influence of the green sea aquaculture and their mechanism of action. The results showed that (1) the efficiency of green level of mariculture industry in China is not high, and the establishment of national marine pasture demonstration zone has not effectively promoted the improvement of green level of mariculture industry; (2) the institutional environment, unreasonable industrial structure, and lack of scientific and technological innovation have an effect on the national oceanic ranch demonstration area as the main causes of failure to effectively promote marine green farming; (3) the establishment of the national multi-period demonstration area in the north significantly hindered the growth of the green level of mariculture and fell into the “policy trap”, while the establishment of the national multi-period demonstration area in the south significantly promoted the growth of the green level of mariculture. The conclusions of this paper provide an empirical basis and reference for the improvement of the national marine pasture demonstration zone policy and the green transformation of mariculture to a certain extent.
