基于POI数据的南京市便利店空间分布特征及影响因素

Spatial distribution characteristics and influencing factors of convenience stores in Nanjing based on POI data

便利店作为城市零售商业的主要载体,其合理的空间分布对实施扩大内需战略和畅通经济循环至关重要。基于南京市POI数据,运用核密度估计、缓冲区分析、有序多分类Logistic等研究方法,探讨南京市便利店空间分布特征及区位选择成因。研究发现(:1)南京市便利店空间分布总体呈现“一主多副”的不均衡发展格局,集中分布在江南主城区,小范围聚集在江北新主城区,低密度零星分布在副城区(;2)基于道路格网单元、地铁站点的便利店热点区分布与识别,发现便利店沿道路分布特征明显,与地铁站点相平行分布特征突出,但在不同站点的分布差异较大(;3)各品牌便利店的空间集聚特征表现不同,但与各自的品牌定位、经营战略等基本吻合,与城市商圈布局相得益彰(;4)交通、人口、租金等因素影响便利店的空间分布,且影响程度存在差异。研究结果可为优化商业网点空间布局及商业规划等提供科学依据和理论支撑。

Convenience stores,as the main carrier of retail commerce,the reasonable spatial distribution of convenience stores is very important for the implementation of the strategy of expanding domestic demand and unblocking the economic cycle.Based on the POI data of Nanjing,kernel density estimation,buffer zone analysis,and ordered multicategorical logistic were used to explore the spatial distribution characteristics and causes of location selection of convenience stores in Nanjing.The study finds that:(1)The spatial distribution of convenience stores in Nanjing generally presents an unbalanced development pattern of"one main store and many vice stores",which is concentrated in the main urban area of Jiangnan,gathered in the new main urban area of Jiangbei in a small range,and scattered in the sub urban area with low density.(2)Based on the distribution and identification of convenience store hotspots in road grid cells and subway stations,it is found that convenience stores have obvious distribution characteristics along the roads and parallel distribution characteristics with subway stations,but the distribution of different stations varies greatly.(3)The spatial clustering characteristics of each brand of convenience stores are different,but they basically match with their respective brand positioning and business strategies,and complement the layout of urban shopping areas.(4)Factors such as traffic,population and rent affect the spatial distribution of convenience stores,and there are differences in the degree of influence.The research results provide scientific basis and theoretical support for optimizing the spatial layout of commercial outlets and commercial planning work,etc.
