Abstract:Urban network centrality is an important concept for measuring the status of cities and analyzing urban systems. By distinguishing the construction between static and interactive networks, the paper builds a comprehensive network centrality evaluation system separating scale data and interaction data. In the empirical analysis, this research utilizes the gravity model, social network analysis and QAP method to extract nodal indexes and describes overall urban network profiles to compare the urban system patterns of Jiangsu province and Guangdong province. Research reveals that the concept of centrality has a process of transition from the traditional central place hierarchy to the interaction nodality of urban network and that the empirical measurement of centrality should include city scale data and inter-city connection data the same time. It finds that: 1) It is effective and scientific to identify the primate cities from the perspective of the network centrality of two types of urban data. 2) The network centrality evaluation system can clearly and meticulously describe the overall structure of the provincial urban system. 3) In the evaluation system of network centrality, the static network and the interaction network do not have significant correlation, while there is a significant positive correlation between different interaction networks.
