中文摘要：

连锁超市已成为中国大城市内部零售商业的主要业态。针对目前研究中对城市内部尺度连锁超市空间布局问题关注不足,本文以南京市苏果超市为例,从空间格局演化、集聚分布状况、不同类型超市的区位选择等方面进行分析。研究方法包括点模式分析、空间密度分析和空间自相关分析等。结果发现：南京市苏果超市的空间总体分布呈中心到外围递减的倒＂U＂型集聚特征;不同类型苏果超市的分布特征不同,华润卖场的空间分布相对分散,社区店、便利店的分布相对集聚;空间分布热点呈蔓延扩散与等级扩散混合模式。运用BinaryLogistic二分逻辑回归对影响超市区位选择的因素进行计量分析,结果表明经济发展情况、消费者规模、交通通达性、居民购买力、城乡差别、公司战略等多种因素,通过综合作用机制,共同推动了南京市苏果超市的空间分布格局。

英文摘要：

Chain supermarkets have been main formats of retail business within large cities of China. Current studies pay little attention to spatial distribution of chain supermarkets on the scale of internal city. Taking Suguo supermarkets in Nanjing as an example, this paper focuses on spatial pattern evolution, agglomeration, and location decisions of different types of supermarkets using research methods including point pattern analysis, space density analysis and spatial autocorrelation analysis. The results show that Suguo supermarkets present an inverted-U-shaped pattern with the mode of extending to the surrounding area around the core of the downtown area. Different types of supermarkets present different distribution characteristics. Resource stores are relatively disperse while community and convenience stores are relatively concentrated. The spatial distribution of hot spots shows a mixed mode of spreading diffusion within the main city and hierarchical diffusion from the main city to the suburbs. Using binary logistic regression to analyze the factors that influence the location decision of supermarkets, we find that a variety of factors including economic development, scale of consumers, transport accessibility, purchasing power of residents, urban-rural divide and corporate strategy formed the spatial distribution pattern of Suguo supermarkets in Nanjing jointly through a comprehensive mechanism.
