【摘要】：以河南省126个县域(市区)为研究单元,运用2014年银行业的12 369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。
[Abstract]:Taking 126 counties (urban areas) of Henan Province as the research unit, using the data of 12,369 dot points of the banking industry in 2014, and using the linkage network model for reference, The complex network analysis tools and spatial analysis software are used to measure and analyze the financial network of Henan province. It is found that: (1) Zhengzhou is the financial core of Henan Province and Luoyang is the sub-financial core from the point of view of financial connectivity; (2) the financial core has a higher degree of financial connection and a strong external financial connection, and the spatial distribution of bank branches does not fully follow the administrative hierarchy system of traditional geographical space; (3) under the joint action of the physical infrastructure network and the virtual network of the bank network, the financial network of Henan Province shows the double characteristics of grading and networking; (4) in the financial network, Zhengzhou-Luoyang has the highest degree of financial connectivity, the degree of financial connectivity has a certain degree of polarization, and in the space presents the pattern of "one body and two wings", and the phenomenon of financial aggregation in the north of Henan is more obvious than that in the south of Henan; (5) the topology diagram of financial network in Henan Province has larger aggregation coefficient and smaller average shortest path, and the degree distribution shows power law distribution in logarithmic coordinates. It is shown that the whole network has the characteristics of small-world network and scale-free network structure in complex network at the same time.
