Information-flow Based Comparative Research of Urban-region Relations—A Case Study of Ma’anshan and Wuhu
通过电话流量和网络帖子两类数据，比较马鞍山和芜湖两个相似城市的区域关系差异，发现马鞍山的区域关系集中且依赖特定城市，芜湖则更分散且层次丰富。
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 the urban-region relations,is comprehensive,moment to moment and has relatively low locale-dependence.So it can be 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.
