Abstract
The sports industry plays an important role in promoting regional economic construction, citizens' health and quality of life, and has good development resilience and development prospects. However, the existing sports industry research has the shortcoming of paying insufficient attention to the characteristics of the spatial evolution of sports resources and the influencing factors. This paper applies the nearest neighbor index, kernel density analysis, standard deviation ellipse analysis, GeoDetector and other methods to study the spatial evolution characteristics of national sports industry bases in Chinese urban agglomerations and their influencing mechanisms from the perspectives of distribution type, distribution density and distribution orientation. The results show that, firstly, at the early stage of sports resources development in Chinese urban agglomerations, the national sports industry bases were discretely and randomly distributed; later on, as the accumulation of resources became more and more abundant, the tendency of agglomeration of the national sports industry bases began to be emphasized. Secondly, the sports resources of Chinese urban agglomerations as a whole show a tendency from a scattered structure to a cluster structure, and the spatial distribution is extremely uneven. Thirdly, the spatial center of gravity of the national sports industry bases shows the dynamic migration development trend of "northwest-northeast-southwest", and the development gap between east and west, south and north is gradually narrowing. Fourthly, the economic base, potential market and policy environment play an important role in interacting with other factors and then empowering the cultivation of sports resources, but there is no empirical evidence to confirm the specific conduction path of this empowering effect.
