Exploring a New Approach to Define Urban Center:A Study on Producer Services Distribution in Shanghai
基于地统计和城市空间建模，提出用莫兰指数识别潜在中心、再用回归分析验证的新方法，发现上海生产者服务业形成外滩和南京西路双中心，且国内外企业分布有别，揭示中国城市空间重构的独特性。
On the basis of Geo-statistics and urban spatial modeling methods,this paper presents a new approach to identifyurban center,that is introducing the Moran's Index to search the potential centers and then using regression analysis to examine them.By analyzing Firm Inventory data collected from Shanghai Administration of Industry and Commerce,it is found that the producer service firms are highly concentrated in central Shanghai and formed two centers:the Bund and the Nanjing West Road(NJWR).Interestingly,the domestic firms tend to clustering in the Bund while the overseas firms tend to clustering in the NJWR.This twin center pattern is distinct withscatterationandpolycentricitypatterns observed in the Western cities,which unfolds the uniqueness of urban spatial restructuring in China.
