THE SPATIAL DISTRIBUTION OF LARGE SUPERMARKET IN NANJING
基于租金理论和空间需求曲线，利用GIS分析南京大型超市与地价、交通、人口密度的关系，发现超市多位于次级商业中心、主干道旁和大型居民区附近，服务半径约700米，竞争激烈。
Guided with the rent theory and spaces demand curve and using GIS,this article analyzes the relationship between the spatial distribution of large supermarket and land price,transportation and population density in Nanjing,and discusses the features and reasons of supermarket spatial distribution.The conclusions are as follows:first,most supermarkets are located the second level of commercial center.Second,most supermarkets are perched on both sides of main roads and traffic nodes which have convenient transportation.Then,supermarkets run to the large residential area rather than core area which is densely populated.Finally,by the buffer of service radius of supermarkets at GIS,the service radius of supermarkets in Nanjing is about 700m,and supermarkets are so densely that the competition is too intense.
