Research on the Spatial Arrangement of Retail Business in the Central City of China's Megacity-A Case Study of Nanjing

Abstract

Urban retail business development is an extremely important factor in promoting the development of urban physical space and socio-economic culture. Urban retail commercial space layout is the geographical distribution and geographical combination of commodity circulation network, and it is one of the research areas in the development of urban central area space. In recent years, the research on the urban center area has mainly focused on the perspective of land use and so on. From the perspective of industry, it is rare to study the urban center area. With the advent of the era of big data, this paper takes the Xinjiekou Central District of Nanjing as an example to obtain a POI data acquisition database, and analyzes the spatial layout of retail business in Nanjing. Based on the quantity and structure of land use in Nanjing and the direction of urban expansion, the relationship between the expansion of urban land use industry and retail business space is analyzed, which provides a guide for the research on the retail business status in urban centers.
