总结分析当今世界各主要经济体的银行间市场体系的网络结构特征,指出随机网络和无标度网络是目前各国银行间市场的主要网络结构形态。并进一步通过模型说明和数值仿真揭示了这两种不同的网络体系下银行间市场的相继违约风险发生过程和演化特征,分析了网络结构对于银行体系风险的影响,指出无标度的银行体系结构会带来更大的相继违约风险。 This paper summarizes and analyzes the characteristics of the network structure of the inter-bank market system in all the major economies in the world today. It points out that stochastic networks and scale-free networks are the major network structures of the interbank markets in various countries at present. And further through the model description and numerical simulation to reveal the occurrence and evolution characteristics of the successive default risk under the two different network systems in the interbank market, analyzes the impact of network structure on the banking system risk, points out that the scale-free banking architecture Will bring greater risk of successive defaults.
