Abstract:

Convenience stores, as the main carrier of retail commerce, the reasonable spatial distribution of convenience stores is very important for the implementation of the strategy of expanding domestic demand and unblocking the economic cycle. Based on the POI data of Nanjing, kernel density estimation, buffer zone analysis, and ordered multicategorical logistic were used to explore the spatial distribution characteristics and causes of location selection of convenience stores in Nanjing. The study finds that: (1) The spatial distribution of convenience stores in Nanjing generally presents an unbalanced development pattern of "one main store and many vice stores", which is concentrated in the main urban area of Jiangnan, gathered in the new main urban area of Jiangbei in a small range, and scattered in the sub urban area with low density. (2) Based on the distribution and identification of convenience store hotspots in road grid cells and subway stations, it is found that convenience stores have obvious distribution characteristics along the roads and parallel distribution characteristics with subway stations, but the distribution of different stations varies greatly. (3) The spatial clustering characteristics of each brand of convenience stores are different, but they basically match with their respective brand positioning and business strategies, and complement the layout of urban shopping areas. (4) Factors such as traffic, population and rent affect the spatial distribution of convenience stores, and there are differences in the degree of influence. The research results provide scientific basis and theoretical support for optimizing the spatial layout of commercial outlets and commercial planning work, etc.
