Abstract: In order to scientifically evaluate the coordinated development relationship between China’s feed industry and aquaculture industry and identify the main factors driving coupling coordination, based on the provincial panel data from 2015 to 2019, the coupling pattern and driving factors of feed industry development and aquaculture scale were studied by using entropy method, coupling coordination model, radar map, spatial visual expression, linear regression and other methods. The results showed that： ①The development of China’s feed industry showed a pattern of “high in the south, low in the north, high in the east and low in the west”; ②The scale of aquaculture industry presented a pattern of “high in the surrounding areas and low in the central areas”; ③The coupling and coordination degree between the development of feed industry and the scale of aquaculture industry was in the pattern of “high in the east and low in the west, and high in the surrounding areas and low in the central areas”; ④The coupling and coordination level of most provinces had not significantly improved in recent five years; ⑤The long-term dominant factor in the coupling imbalance area between the development of feed industry and the scale of aquaculture was the scale of animal husbandry, and the long-term dominant factor in the coordination area was the management and maintenance ability of feed enterprises. In view of this, the government could promote the coordinated development of feed industry and breeding industry by guiding the joint production of small and medium-sized feed enterprises and introducing talents.

Key words: feed industry development, scale of aquaculture, coupling coordination, spatiotemporal evolution, driving factor
