基于超网络的互联网金融均衡问题研究

Study on Internet Financial Equilibrium Problem Based on Supernetwork

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, a- nalysis 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 opti- mality conditions. Functions of credit risk and operational risk were included, considering the in- creasing credit risk and operational risk in the environment of Internet. Using the variational ine- quality 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 satura- tion condition of Internet finance can be studied later. Finally, a simulation example is given to verify the validity of the supernetwork model.
