课题采用复杂网络方法从网络拓扑结构、危机传播动力学、演化博弈和风险传染控制策略等方面研究中国企业联保互保的担保圈网络和银行间网络，通过设定不同的控制规则，引入企业、银行、政府机制，调节模型参数，来预测、判断、控制网络的风险传播。进而建立“企业-银行”耦合网络，剖析其结构及交互影响中产生的级联效应，设计免疫策略使耦合网络的可持续性、适应性和演化性达到最大化。在我国局部地区担保圈危机频发和银行系统性风险不断增加的背景下，研究具有重要的现实意义。本研究有三个特色：1、根据企业、银行网络的拓扑结构特点，探索合理的网络生成方法，在此基础上研究单网络中风险的传播与控制。2、国内首次构建“企业-银行”耦合网络，针对耦合网络中风险传播的新特点，探索在双网络交互中的风险控制策略。3、研究中使用阈值模型、大规模蒙特卡洛仿真、演化博弈等方法构建模型。力图为中国转型期经济金融系统风险的控制提供政策上的参考。

Our research use complex network as a method to study the guarantee network based on the guarantee relationship between firms and the interbank network based on interbank lending from aspects such as the network topology, dynamic risk contagion, evolutionary game and risk control strategies. We set different control rules, introduce mechanism of enterprise, bank, government, adapt model parameters， to forecast, determine and control the risk contagion of these two networks. Then, we establish "firm-bank" interdependent networks, analyze its structure and the cascade effect due to their interaction, design immunization strategies to optimize the sustainability, adaptation and evolution of the interdependent networks. With guarantee network crisis deteriorating in some region of China and the increasing of interbank market dependency, our research has important significance. Our research has the three following features: 1.We explore reasonable network generating method based on the topology of the two networks; 2.We first construct the "firm-bank" interdependent networks, focusing on the new features of risk transmission and explore the risk control strategy in the interacting between the two networks; 3.We use threshold model, large scale of Monte Carlo simulations and evolutionary game to build our model. We hope to give advice from our research to the policy-making for our government on risk control issue in transition economy.
