省域城市网络中心性测度及比较研究——以江苏省和广东省的对比分析为例

城市网络中心性是衡量城市地位、分析城市体系的重要概念.本文在剖析中心性理论内涵的演化后,提出网络中心性应当同时体现规模等级和要素流动的水平.通过区分静态网络和联系网络,论文构建了基于规模数据和流动数据的网络中心性评价体系,并以江苏、广东为例进行实证分析.研究发现:①从规模和联系两类城市网络中心性的视角识别首位城市是有效...

MEASUREMENT AND COMPARISON RESEARCH OF PROVINCIAL URBAN NETWORK CENTRALITY:TAKING COMPARATIVE ANALYSIS OF JIANGSU AND GUANGDONG AS EXAMPLE

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.
