The study of the industrial structure characteristics of the main stadium area of the large-scale comprehensive sports games is to promote the high-quality development of"stadium-industry-city".This study takes the main stadium areas of the 9th to 14th National Games held in the 21st century as samples,uses the POI information of 12 types of industries within a 3000 m radius and uses kernel density estimation and industrial index as the research methods,to explore the main stadium area of different construction nature's industrial structure characteristics in terms of industrial quantity,industrial space and industrial circle.The results showed that:1)The main stadium areas generally show the distribution characteristics of industrial quantity of"renovated and expanded area>early new-built area>lately new-built area"and the quantitative characteristics of industry categories of"productive service industries>consumer service industries>public service industries",which are in line with the expectations of local governments for industrial development.2)The main stadium areas'industrial agglomeration has the diffusion characteristics of"center-periphery"and the spatial characteristics of"partitioned-single hot spot","dense-multiple hot spots"and"hollow-multiple hot spots".3)The main stadium areas generally present a"four-circle"industrial circle structure,showing a"functional-public-marketable"industrial circle from the inside to the outside,but the different construction areas'industries focus circle varies.Practical implications are proposed in three dimensions:combining multiple overlaps and fine development,matching the synergy of circles and local conditions,and linking short-term benefits with long-term planning,so as to help large-scale stadiums scientifically embed in the city's high-quality development.
