以河南省126个县域(市区)为研究单元,运用2014年银行业的12369个网点数据,借鉴连锁型网络模型,运用复杂网络分析工具和空间分析软件对河南省金融网络进行综合测度与结构分析.研究发现:①从金融连接度看,郑州是河南省的金融核心,洛阳是次金融核心;②金融核心具有较高的金融联系度和较强的对外金融联系,同时银行网点在空间上的布局并不完全遵循传统地理空间的行政等级制度;③在实体基础设施网络和银行网点虚拟网络共同作用下,河南省金融网络表现出了等级化和网络化的双重特征;④金融网络中,郑州—洛阳的金融连接度最高,金融连接度存在着一定程度的极化现象,并在空间上呈现出"一体两翼"的格局,且豫北的金融聚集现象较豫南明显;⑤河南省金融网络拓扑结构图具有较大的集聚系数和较小的平均最短路径,同时度分布在对数坐标中呈现幂律分布,说明整个网络同时具有复杂网络中的小世界网络和无标度网络结构特征.%Taking 126 counties as the analytical unit and using the 12369 network data of the 2014 bank branches,and measured financial network of Henan Province,meanwhile with the help of complex network analysis tools and spatial analysis software. According to the financial connection degree,Zhengzhou and Luoyang respec-tively for financial core and secondary financial core in Henan. The financial core has higher financial links degree and with foreign financial links,at the same time,the layout of the bank branch in space is not entirely follow the traditional geographical spatial administrative hierarchy. Under the together action of the physical infrastructure net-work and virtual network bank outlets,the financial network based on the layout of bank branches showed the dual characteristics of hierarchical and network. There is obvious financial agglomeration phenomenon in financial link of Henan Province,and showing the spatial distribution pattern of"one body and two wings",while the financial ag-gregation in north is more obvious than that in south. The topology structure graphs of Henan financial network based on the layout of bank branches has larger clustering coefficient and smaller average shortest path,and degree distribution shows a power-law distribution in the logarithmic coordinate,at the same time,it has a complex net-work of small world network and scale-free network structure characteristics.
