The construction of urban commercial sports facilities plays an important role in improving the national fitness system. This article takes commercial sports facilities in Xi'an as the research object, and selects POI data from 2013, 2016, 2019, and 2022 to explore their spatiotemporal evolution and causes. Research has found that the spatial distribution of commercial sports facilities in Xi'an is a multi-core agglomeration, with expansion direction similar to the urban development direction; Population, economy, transportation, and spatial location factors all have a significant impact on the spatial pattern of commercial sports facilities in Xi'an. Among them, road network density has the greatest impact, followed by population density, nighttime light index, and street distance from the city center. The density of public transportation and subway stations, per capita income, and distance from universities have a relatively small impact.
