Abstract

Community business is the foundation of urban commerce, an important carrier to meet the comprehensive consumption of residents, and an important element of urban quality improvement. Based on the collection and processing of internet big data, combined with the understanding of the connotation of community business, this paper uses GIS spatial analysis technology and nuclear density analysis technology to analyze the spatial distribution characteristics and format changes of community business in the Chongqing. The results show that: (1) The community business in the Chongqing shows a state of "the south is more important than the north". (2) The community business in the Chongqing shows the form of "multi-core + multi-node". In addition to the obvious clustering of community business in the surrounding city business area, there are also many strong community businesses co-existing, and its nuclear density value is comparable to that of the community business in the surrounding city business area, which is in line with the multi-group spatial layout in the Chongqing. (3) There is a strong spatial correlation between the community business and the resident population as a whole, the correlation coefficient is 0.82. (4) From 2014 to 2019, the growth of community business space in the Chongqing is mainly within the inner ring, while showing the trend of diffusion from the inner ring to the outer ring. (5) From 2014 to 2019, the number of commercial shopping facilities in the Chongqing increased, while the number of catering facilities decreased.
