Analyze Of The Evolution Mechanism Of Bank-Enterprise Financing Network

A sound financial system is the national economy that can not be separatedfrom the normal operation, bank and enterprise in the financial system as animportant participant, plays a central role. The bank and the bank, the enterpriseand the enterprise, bank and enterprise exist between the complex relationship,in each other business process is accompanied by a large amount of money toflow, therefore, by accounts as nodes, the relationship between accounts cashflow as sides they form a complex structure with the financing network.Research and analysis of the financing network of the bank and enterprise somebasic characteristics and transmission characteristics so as to financial oreconomic crisis prevention provide certain theoretical basis.This paper in financing and the complex network theory basis, using thebasic idea of behavioral economics, constructs financial network which refersto bank accounts and enterprise accounts as nodes, and the relationship betweenaccounts cash flow as sides, and the growth of the financing network, evolutionmechanism and transmission characteristics are analyzed. Specific content asfollows:First, the paper analysis the basic operations of commercial the bank andthe enterprise funds into and out way. Afterwards, some basic features as theflux, direction and velocity of capital flows among the corporate accounts aredecomposed. And on the basis of some business relations, decompose the bankand enterprise financing network expression way.Next, based on the expression of financing network to determine,this paperuses the traditional scale-free network model and the algorithm based ondescription, refers to the basic idea of behavioral economics,builds a financingnetwork of the growth of the evolution model by assuming, then analyses themodel. Through the analytical results can be seen, when the financing networkis large, whatever developing or decaying, the model shows the characteristicsof scale-free, the degree of nodes in network follows power-law degreedistribution for2. In theory the results after that, in order to verify the reliability of the models, this thesis makes a simulation analysis adopting the simulateddata provided by the financial networks simulation platform based on the Agent.Finally,based on the scale-free characteristics, using the dynamics theoryof the spread of knowledge, in infectious disease model based on the traditionalanalysis, this paper puts forward the financing network nodes in factclassification assumptions, and the financing network nodes are divided into thecrisis nodes, easy to be affected nodes and resistance nodes, then analyses themodel using method of average field, and derives the critical value of financialcrisis among financing network.
