中国三大城市群金融集聚:空间网络及结构分化

金融是国家重要的核心竞争力,金融集聚是推动城市群崛起的重要驱动力。本文基于因子分析和引力模型,研究了2007~2017年京津冀、长三角和珠三角三大城市群的金融集聚及其空间网络。结果发现:从整体来看,三大城市群的金融集聚网络逐步从分割走向融合,且上海在整个金融网络中居于核心位置;从局部来看,城市群内部金融集聚网络的结构差异明显,京津冀表现为主次型单一结构,北京位于绝对核心;长三角为多中心均衡结构,且江苏的金融中心程度明显高于浙江;珠三角为穗深双核结构,深圳的上升趋势明显。据此,应基于城市群金融集聚网络的不同特征,差异化地整合和优化金融资源配置,为区域一体化和经济高质量发展提供高质量的金融服务。

Financial Agglomeration of China's Three Major Urban Agglomerations:Spatial Correlation and Structural Differentiation

Finance is the core competitiveness of a country,and financial agglomeration is an important driving force to promote the rise of urban agglomeration.Based on factor analysis and gravity model,this paper studies the financial agglomeration and its spatial network of three major urban agglomerations,namely Beijing-Tianjin-Hebei,Yangtze River Delta and Pearl River Delta,from 2007 to 2017.The results show that,on the whole,the financial agglomeration network of the three major urban agglomerations gradually moves from segmentation to integration,and Shanghai occupies the core position in the entire financial network.From a local perspective,there are obvious differences in the structure of financial agglomeration network within the urban agglomeration.The Beijing-Tianjin-Hebei urban agglomeration presents a single structure of major and secondary type,with Beijing at the absolute core.The Yangtze River Delta is a multi-center balanced structure,and the degree of financial center in Jiangsu is obviously higher than that in Zhejiang.The Pearl River Delta is a double core structure with spike depth,and the uptrend of Shenzhen is obvious.Further,based on the different characteristics of the financial agglomeration network of urban agglomeration,the differentiated integration and optimization of financial resource allocation can provide high-quality financial services for regional integration and high-quality economic development.
