Abstract: Based on the perspective of the industrial chain, the connotation of high-quality development of fishery was systematically expounded, and a high-quality evaluation index system of fishery with 20 indicators in four dimensions,including upstream （breeding, feed production）, midstream （medical service, aquaculture system）, downstream （logistics transportation, primary processing, deep processing） and sustainable development, was constructed. Based on the data of counties （cities and districts） in Hubei Province from 2010 to 2019, the spatial and temporal evolution of high-quality development of fishery was analyzed, and the coupling relationship between two subsystems from the perspective of the industrial chain was measured. The results showed that the high-quality development level of fishery in Hubei Province increased first and then stabilized. The high-quality development areas were distributed in the Yangtze River and Han River Basins. The coupling degree among fishery industries in Hubei Province was in a highly coupled state, but the coordination degree was basically in a serious imbalance state. The coupling degree of each link in the fishery industry chain of each county （city and district） was high, but the coordination degree was basically in a serious imbalance state. Therefore, the coordinated development of all links of the fishery industry chain should be paid attention to, and a whole industry chain of production, processing and sustainable integration should be built according to the idea of “extending the first industry, connecting the two sides of the second industry, and taking the high end of the third industry”.

Key words: high-quality development of fishery, industrial chain, entropy value method, coupling coordination degree, Hubei Province
