摘要
借鉴链锁网络模型思想,选取银行、证券、保险等金融企业数据,从企业空间布局的视角构建关中平原城市群网络。采用社会网络分析方法,从网络总体属性和节点属性测度关中平原城市群的网络结构特征。研究结果显示:关中平原城市群网络具有一定的层级性、核心—边缘结构特征;基于细分行业构建的关中平原城市群网络存在明显的分异性,银行、证券、保险三类金融行业的发展水平存在差异,证券业的提升空间较大;城市群网络内的金融集聚性较强,且在一定程度上存在“金融排斥”现象;城市网络内多中心趋势仍不明显,没有形成有效的次级区域中心城市。
Using the chain network model,this paper chooses the enterprise data of banks,securities,insurance and other financial institutions to construct the network of Guanzhong plain city group from the perspective of enterprise spatial layout.Using social network analysis method,we measure the network structure characteristics of Guanzhong plain city group with the overall attributes and node attributes of network.The results are as follows.Firstly,the urban agglomeration network in Guanzhong Plain has certain characteristics of hierarchy,core and edge structure.Secondly,there are obvious differences in the networks based on subdividing industries for the Guanzhong Plain city group.There are differences in the development level of three types of financial industries which includes banks,securities and insurance,and there is a large space for the improvement of the securities industry.Thirdly,the financial agglomeration in the city group network is strong,and to some extent,there is“financial exclusion”phenomenon.Lastly,the trend of multi-center in urban network is still not obvious,and no effective sub-regional central city has been formed.
