淮海经济区主要城市城市流强度动态分析

Analysis of the Urban Intensity of Flow for Main Cities in Huaihai Economic Zone

采用定量分析方法对淮海经济区主要城市的城市流强度进行分析。基于城市流理论和城市流强度的分析方法,对淮海经济区主要城市区位商、外向功能量和城市流强度进行了分析,揭示区域主要城市之间的联系情况。经过实证测算,我们从城市流强度角度证明了淮海经济区缺少一个或多个强有力的中心城市,城市流强度普遍较低,城市之间对外服务的功能弱。

By using quantitative analysis,this paper analyses the urban intensity of flow for main cities in Huaihai Economic Zone.Based on the urban flow theory and analytical method,the paper analyzes the location quotient,the extrovert energy and the intensity of urban flow of the urban flow for the main cities in Huaihai Economic Zone and reveals the link situation for main cities in the area as well.After empirical measurements,we prove that the zone needs one or more strong central cities;the intensity of urban flow is generally low and the external service functions among the cities＇ are also weak.
