Study on the spatial distribution characteristics and spatial symbiosis of living supermarkets based on GIS

By using the POI data of Gaode, we screened out the life supermarket system, and studied the spatial distribution characteristics of life supermarket system and its spatial symbiosis with the surrounding residential areas. The analysis found that: ① The spatial distribution pattern of Chongqing’s main city supermarkets is consistent with the "multi-center group" urban structure. The development of supermarkets in the main urban area presents the "Matthew Effect", and it still faces several major business districts within the inner ring and its surroundings. Centralized, another university town relies on stable student group demand, showing a new growth direction; ② Convenience stores have relatively homogeneous cluster characteristics, are mainly developed on more mature commercial areas, and have achieved rapid growth in recent years increased by 1.2 times; ③ The overall distribution of imported merchandise stores in the main urban area is small clusters, and the concentration degree in the GuanYinqiao area is the most prominent. Compared with other types, the concentration degree is higher in the Haier Road area near the bonded port area; ④ Living areas with a high degree of compounding of the living supermarket system around the community are mainly distributed within the inner ring and have a high degree of spatial fit with the major business districts. Outside the inner ring, they are mainly distributed in the north of Beibei City, Beibei Old City, Yudong- and Lianglu.
