Village-Town System in Suburban Areas Based on Cellphone Signaling Mining and Network Hierarchy Structure Analysis

Suburban villages are strongly influenced by cities. Understanding the relationship between urban and rural as well as the hierarchy of villages contributes to optimizing the structure of village-town, allocating resources effectively as well as coordinating the relationship between urban and rural areas. Taking the rural area of Qin and Han New City as the research object, this paper obtained the number of contact flows between urban and rural areas from cellphone signaling data mining and constructed a network with hierarchical system. The influence scope and hierarchy of city and village nodes in the network could be measured by conducting the primary linkage analysis. The effect intensity and radius of the central villages as well as the relationship between villages could be calculated by the multiple linkage analysis. Furthermore, according to the urbanization potential and the characteristic regions of cites, the regional village-town system could be finally determined. This study has shown that 89.4% of the villages were influenced by the surrounding cities strongly, and the influence range of the cities was 6.2-28.3km. There were 13 “Centrality” villages in this region, which was lean to city, traffic convenience and divisional centralized. Totally, 19 groups of villages should be merged and 3 groups should be developed together. Besides, two kinds of village-town systems were formed in this region, and the villages were classified into five categories for guidance. Moreover, the research results could not only provide a helpful method to determine the village-town system structure under the strong influence of cities but also offer a better way for resources allocation between urban and rural smartly and equally.
