Analysis of the spatio-temporal distribution of Chinese professional football clubs and influential factors based on empirical evidence of clubs

The frequent relocation of professional football clubs is a phenomenon unique to Chinese professional football, which has long attracted extensive attention from policy makers and scholars. Using data on spatial geography and competitive levels between 1994 and 2021, this research explores the spatial distribution and migration characteristics of top professional football clubs in China, in which GIS spatial analysis and exploratory spatial data analysis (ESDA) were used to analyze the influence of the regional economic, demographic, and developmental levels of the sports industry and institutional supply on the distribution and migration of clubs. The results indicate the following: (1) the overall spatial distribution of professional football clubs in China shows the pattern of "more in the east and less in the west", and the degree of club concentration gradually increases over time; (2) the migration frequency and downward migration of professional football clubs in China gradually decreased during the period of C League and CSL, and the overall situation tends to be stable; and (3) in the early stages of development of professional leagues, changes in ownership and local policy supply had a significant impact on the distribution and migration of professional clubs. As time progressed, the top-down design of institutional arrangements changed, and the regional economic, demographic, and developmental levels of the sports industry gradually became the essential determinants of the distribution and migration of professional football clubs. In the future, Chinese professional football clubs should focus on rationalizing the advantages of the regional economy, demography, and sports industry as well as reducing their reliance on short-term resources, such as corporate investment and policy benefits.
