Abstract 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.
