为了研究互联网金融环境下日益复杂的金融网络,引入超网络理论,分析各决策者之间的竞争合作关系以及各自行为和最优化条件;考虑互联网环境下加剧的信用风险和操作风险,引入信用风险函数和操作风险函数,建立了由资金拥有者、互联网金融中介、传统金融中介、资金需求者构成的超网络模型。运用变分不等式理论,研究互联网金融超网络均衡解的存在性条件和唯一性条件,给出整个互联网金融网络的均衡条件,为下一步研究互联网金融发展趋势和饱和状态奠定基础。最后运用算例进行仿真,验证了模型的有效性。
Under the development of the Internet finance, supernetwork theory was included to study the increasingly complex financial network. A framework was developed for modeling, analysis and solutions to multitiered Internet financial network problems with investors, Internet financial intermediaries, traditional intermediaries and investees. The competitive and cooperative relationships between various decision-makers were explicated, as well as their behavior and optimality conditions. Functions of credit risk and operational risk were included, considering the increasing credit risk and operational risk in the environment of Internet. Using the variational inequality theory, the existence and uniqueness of the equilibrium solution is studied.The governing equilibrium conditions of the Internet financial network is also given so that the trend and saturation condition of Internet finance can be studied later. Finally, a simulation example is given to verify the validity of the supernetwork model.
