Comprehensive evaluation of the high-quality development level of China's marine fisheries from the perspective of the industry chain
Industrial chain construction is the main battlefield for high-quality industrial development,and improving the modernization level of the marine fishery industry chain is a necessary condition to support the high-quality development of the marine economy.In order to further enhance the linkage level of the regional industrial chain of marine fisheries and promote the transformation and upgrading of the marine economy,this article takes 11 provinces(autonomous regicipaliton,muniy)along the coast of China as the research object.Based on the multidimensional connotation of the industrial chain,starting from the four dimensions of the innovation chain,value chain,supply chain,and spatial chain,we constructed an evaluation index system for the high-quality development level of marine fisheries;Using TOPSIS,AISM,and obstacle degree models,the spatiotemporal evolution characteristics and influencing factors of high-quality development of marine fisheries in coastal provinces(autonomous region,municipality)of China from 2006 to 2020 were analyzed,and corresponding suggestions and measures were proposed.The results indicate that:(1)In terms of time,the high-quality development level of China's marine fisheries has been improving year by year during the research period,and the closeness values of various dimensions have shown varying degrees of fluctuation and upward trend.Among them,the closeness values of the innovation chain dimension are relatively high and stable,while the closeness values of the value chain and spatial chain dimensions have grown rapidly.There is still significant room for improvement in the closeness values of the supply chain dimension.(2)In terms of space,there are significant differences in the performance of high-quality development regions in China's marine fisheries,with different advantages and disadvantages in four dimensions.(3)In terms of hierarchical division of advantages and disadvantages,the overall level of high-quality development of marine fisheries in the study area is relatively obvious,with Shandong performing best,Hebei and Hainan performing worse.Except for the three activity elements of Jiangsu,Shanghai,and Guangxi,other regions have stable development and a rigid structure.(4)In terms of influencing factors,the level of innovation chain is the biggest obstacle to the high-quality development of Marine fisheries,and the level of value chain and supply chain also have a certain impact.During the study period,the first obstacle factors are X1 aquaculture technology promotion funds,X5 aquaculture technology promotion institutions,and X3 fishermen technical training.Studying the high-quality development of marine fisheries from the perspective of the industrial chain can effectively help the modern fisheries system develop towards informatization and intelligence,and promote high-quality economic and social development.
