A Complex Network Model for Credit and Debt Relationships Analysis of Bank-Firm System

We construct a complex network model of the bank-firm system. Based on the bank-firm balance sheets and their evolution behaviors, the interbank lending relationships, interfirm guarantee relationships and bank-firm lending relationships were established. Simulation results indicate that the complex network model displays a core-periphery structure and maintains the characteristic of the scale-free network. The purpose of this paper is that we propose a complex network of bank-firm system to explain the formation mechanism of bank-firm complex networks which is closer to reality. To maintain the stability of the bankfirm system, this paper has a certain guiding significance.
