【摘要】：基于当前城市网络和金融地理研究,以全国336个地级以上行政单元(城市)为研究对象,以33家国内外银行的88022个网点各城市间的级别和数量分布为基础数据,运用链锁模型、Zipf法则、社会网络分析等研究方法,对中国市间联系和城市节点的结构特征进行分析。研究表明:京津冀、长三角、珠三角、成渝和长江中游等五大城镇密集区之间的联系成为这一网络的主干,东西部网络密度以胡焕庸线为界呈现明显差异;城市联通度的规模分布符合Zipf法则,但呈现明显的双分形特征,各城市的节点度同样以胡焕庸线为界在东西部呈现显著差异;此外,国有银行、股份制银行和外资银行所分别对应的城市整体联通度和相对联通度在空间分布上也存在明显差别;上述结构特征同各城市经济规模和人口规模之间存在较强的相关性。从形成机制上看,朝向集中化和均衡化的一般空间政策和行业空间政策对这一网络格局的形成具有深刻影响。
[Abstract]:Based on the current urban network and financial geography research, this paper takes 336 administrative units (cities) above the prefectural level as the research object, and takes the distribution of the level and quantity of each city among the 88022 branches of 33 domestic and foreign banks as the basic data. By using chain model Zipf rule and social network analysis, this paper analyzes the structural characteristics of urban connections and urban nodes in China. The results show that: Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta, etc. The connection between Chengdu-Chongqing and the five cities and towns in the middle reaches of the Yangtze River becomes the backbone of this network, and the density of the eastern and western regions is obviously different from the Hu Huanyong line, and the scale distribution of the urban connectivity conforms to the Zipf rule. However, there are obvious double fractal features, and the nodal degree of each city is also significantly different from that of Hu Huanyong line in the east and the west. In addition, the state-owned banks, There are also obvious differences in spatial distribution between joint-stock banks and foreign banks. There is a strong correlation between the above structural characteristics and the economic scale and population size of each city. The general space policy and the industry space policy towards centralization and equalization have profound influence on the formation of this network pattern.
