上海市中心城商业网点空间集聚特征综合测度

The comprehensive measure of agglomeration characteristics of commercial sites in central city of Shanghai

基于互联网开放数据,对上海市中心城区内的商业空间网点的集聚特征进行综合测度.研究结果表明:1空间距离方面,上海市中心城区商业网点体现出较为显著的空间集聚特征,多尺度空间集聚特征,整体呈现了"先增后减"的倒U型态势.2空间密度集聚特征方面:上海市中心城区商业网点基本呈现内环内中西部面状集聚,内环外分散集聚,浦西浦东地区差别巨大的特征.3空间热点集聚特征方面:上海市中心城区3种类型的商业网点冷热点分布呈现冷点区域分割包围热点区域的空间集聚特征.对比空间密度集聚特征,应当鼓励发展具有高空间密度但表现为空间冷点的集聚区域,进一步完善该区域的商业结构,提升商业服务质量,使其形成新的商业热点集聚区域.

This paper aims to analysis spatial aggregation of commercial sites in central city of Shanghai.The results show that： 1 In terms of spatial distance,all commercial sites present salient spatial aggregation features. The agglomeration degrees increase and then decrease with the increasing of distance. 2 The kernel density analysis shows that commercial sites aggregate in Middle-west of inner ring area while disperse outside inner ring area. Meanwhile a sizeable difference also reveals between Pudong and Puxi areas. 3 The spatial hot spots of commercial sites mainly concentrate inside inner ring road,while the spatial cold spots distribute evenly outside inner ring road area. Improvements on commercial structure and service quality should be made in cold spots with high density to turn them into new hot spots area.
