通过对2010年全国286个地级以上中心城市相关数据的因子分析,将金融集聚因子降维成规模因子、质量因子和活跃程度3个较稳定的可解释因子,并与2005年相应数据进行比较。根据金融集聚指数,将我国中心城市金融集聚水平划分为全国性金融中心、全国性金融次中心、区域性金融中心、省域金融中心及地方金融中心。借助GIS空间分析技术对全国中心城市金融集聚的空间分布格局进行展现,结果显示我国金融集聚最为显著的区域集中在长三角、京津冀和珠三角地区,上海、北京一天津、广州一深圳构成全国性金融集聚服务中心城市;金融集聚与城市规模有着极强相关性,200万人以上的特大城市是金融活动的主要集聚地;各省区的金融集聚中心一般为其省会城市及其副中心城市。分析金融集聚指数2005--2010年的变化率,全国金融业集聚态势有从全国金融中心向邻近区域扩散的趋势,并向中部和近西部地区的中心城市不断传播。
Financial industry is the core of modern economy and has the trend of spatial agglomeration Based on the data of 286 central cities in 2005 and 2010 and the factor-analysis method,this paper investigated the level and spatial pattern of financial agglomeration on central cities in mainland China. We reduced ten factors measuring financial agglomeration level of each central city into three factors : financial agglomeration scale, agglomeration quality and agglomeration activi- ty. We found that the central cities' factor score could best describe the financial agglomeration level;the city' s types of financial agglomeration could be divided into five classes : national financial center, sub-national financial center, regional financial center,provincial financial center and local financial center. We also found that the financial agglomeration level of the Yangtze River Delta,Beijing-Tianjin-Hebei Region,and Pearl River Delta were higher,and Shanghai,Beijing,Tian- jin,Guangzhou and Shenzhen were the national financial agglomeration service center; the financial agglomeration level had strong relevance with city' s economic and population scale, the megacities with the population of more than 2 million were the centers of national financial activities ,the capital city and/or deputy center city was the provincial financial ag- glomeration center;there was the spatial spreading trend of financial activities from the national financial centers to the neighboring areas ,the central and the near western regions.
