摘　　要：便利店是服务保障民生、促进便民消费的重要商业设施,是十五分钟社区生活圈建设的重要组成部分。本文假设在自由竞争格局下,尚不能完全实现品牌连锁便利店在十五分钟生活圈内的供需匹配,仍需政府规划引导。在此基础上,以南京市中心城区为例,针对六大主流连锁便利店的空间分布现状,分析市场空间竞争和微区位竞争特征与策略,进而利用两步移动搜索法(Two-Step Floating Catchment Area Method,2SFCA)考察连锁便利店基于空间竞争在生活圈内形成的供需关系水平。结果表明:(1)六大品牌连锁便利店在南京中心城区展开了广域的空间竞争,品牌间竞争强度呈现圈层式降低态势,不同品牌的竞争优势区不尽相同。(2)从微区位竞争偏好来看,各品牌临近居住区、服务生活圈的取向明显,其中对居住区具有单一化高倾向的品牌更具有空间分布均衡性,而品牌间对居住-商务-沿路复合型区位的竞争,也有利于提高对居民区的服务供给能力。(3)在现有空间竞争格局下,进一步结合各品牌基于品牌吸引力的供给能力分布以及居民需求分布可知,连锁便利店在生活圈内的供需关系由市中心向外呈现高低起伏的波形分布态势,竞争强度大的区域供需平衡性较高,但大部分区域的连锁便利店尚不能满足居民需求。因此,接受原假设,并从优化调控热点、冷点和盲点地区便利店竞争强度的角度出发,提出促进生活圈内便利店供需平衡的建议。Convenience stores are important commercial facilities that serve ensure people's livelihood and promote convenient consumption,and are an important part of the construction of a fifteen-minute community life circle.This article assumes that under a free competitive,it is still not possible to fully achieve the supply and demand matching of brand chain convenience stores within the fifteen-minute life circle,and government planning and guidance are still.On this basis,taking Nanjing Central Urban Area as an example,the current spatial distribution of the six mainstream chain convenience stores is analyzed,and the characteristics and of market spatial competition and micro-site competition are analyzed,and then the Two-Step Floating Catchment Area Method(2SFCA)is used to examine the level supply and demand relationship formed by chain convenience stores based on spatial competition within the life circle.The results show that:(1)The six brand chain convenience stores have out extensive spatial competition in Nanjing Central Urban Area,and the competition intensity between brands shows a ring-shaped decrease,and the competitive advantage areas of different brands are exactly the same.(2)From the perspective of micro-site competition preference,the orientation of each brand close to the residential area and serving the life circle is obvious among which the brand with a single high tendency to the residential area is more spatially balanced,and the competition between brands for the composite location of residential-commerce-along road is also conducive to improving the service supply capacity to the residential area.(3)Under the existing spatial competition pattern,further combining the distribution of supply capacity based brand attractiveness of each brand and the distribution of residents'demand,it can be seen that the supply and demand relationship of chain convenience stores within the life circle shows aavy distribution trend from the city center to the outside,with high and low undulations,and the areas with
