| Summary: | The large yellow croaker is one of the main economic fishes in Chinese coastal waters. In order to explore the sustainable development of the yellow croaker industry, this paper studied the industrial development law of the yellow croaker from the perspective of industrial agglomeration. The aquaculture industry and fishing industry oflarge yellow croaker were taken as the research objects in this paper, and the method of location entropy and spatial Gini coefficient were used to measure the agglomeration level of the large yellow croaker aquaculture industry and fishing industry from 2011 to 2020. The research found: from the spatial Gini coefficient according to the calculation results, the agglomeration level of the large yellow croaker aquaculture industry was higher than that of its fishing industry. The agglomeration degree of the large yellow croaker aquaculture industry in Fujian Province was the highest compared to Zhejiang and Guangdong, but showing a downward trend. The agglomeration level of the large yellow croaker aquaculture industry in Guangdong Province was relatively low and basically remained stable. The fishing output of large yellow croaker was relatively low, and its agglomeration level was relatively low, mainly concentrated in Liaoning, Guangdong and Hainan Provinces. The location entropy of the large yellow croaker fishing industry in Liaoning showed a downward trend, and the overall location entropy in Guangdong showed an upward trend. The level of industrial agglomeration of large yellow croaker fishing in China had remained basically stable, and the level of industrial agglomeration in fishing areas such as Fujian, Shandong, Jiangsu, Zhejiang and Shanghai was relatively low. Based on the research results and combined with the field research, this paper put forward 3 suggestions: strengthening the technical research on the breeding and processing of the giant yellow croaker; improving the implementation of relevant fishery regulations by the government, increasing the training of farmers, and improving the quality of yellow croaker; and protecting the resources of giant yellow croaker germplasm.
