Study on the agglomeration level and formation mechanism of aquaculture industry in China

Industrial agglomeration plays an increasingly critical role in optimizing the efficiency of resource allocation, promoting local and national economic growth and enhancing international competitiveness. This study constructs a theoretical model of the formation mechanism of aquaculture industry agglomeration and uses location entropy and Geodetector methods to explore the agglomeration level and formation mechanism of China’s aquaculture industry. The conclusions of the study are as follows: (1) There is an industrial agglomeration phenomenon in China’s aquaculture industry, but the degree of industrial agglomeration is not high, and the agglomeration phenomenon shows a weakening trend as a whole. At the same time, the agglomeration level of the aquaculture industry varies greatly among regions; (2) Aquaculture industry agglomeration is the result of the interaction of comparative advantage, external economic and institutional policy environment. The impact of various factors on the agglomeration of the aquaculture industry will change over time; (3) Industrial correlation and production technology level are important influencing factors of aquaculture industry agglomeration, with the highest explanatory power of 82.3 % and 66.9 %, respectively.
