基于信息流的城市—区域关系比较研究——以马鞍山和芜湖为例

Information-flow Based Comparative Research of Urban-region Relations—A Case Study of Ma’anshan and Wuhu

从信息流的角度,选取电信话务量和网络发帖量两组信息流数据,以马鞍山和芜湖为例,进行同一区域中不同中心城市所具有的差异化城市—区域关系特征的比较研究,探索了城市区域关系研究的新方法。数据分析认为:尽管芜湖和马鞍山是两个发展特征相近的区域中心城市,但其区域联系特征具有鲜明的差异性;马鞍山构建的区域联系分布集中,对个别城市依赖度高,而芜湖构建的区域联系分布分散,区域联系结构层次丰富;马鞍山表现出和邻近城市建立强联系,联系跨度较小,区域辐射影响力小,而芜湖在建立邻近联系的同时,能与较远区域的城市形成较强联系,联系跨度大,区域辐射影响范围大。

Urban - region relation is the basis of the construction of regional relation network. It provides references of making regional public policies, which reflects how cities participate in the regional division and cooperation. Information flow, a kind of recognizable element that reflects moment and has relatively low locale-dependence, sO it can be the urban-region relations, is comprehensive, moment to used to measure urban-region relations reliably. Choosing two different sets of data： one for telephone traffic, another for network posts, the comparative study reflects the differentiated urban-region relations of diverse central cities in the same zone and explores new methord of studying urban-region relations. The analysis on information flow shows： Though Wuhu and Ma＇ anshan is two central cities which have similar development characteristics, their regional relations are distinctively different; The urban-region relation constructed by Ma＇ anshan is centralized in distribution and strongly depends on certain cities. However, the urban-region relation constructed by Wuhu is dispersive and its structure of regional relation has a more abundant level; Ma＇ anshan tends to build strong relations with neighboring cities and its regional influence is weaker while Wuhu tends to build strong relations with both neighboring cities and remote cities.
