Evolutionary Game Analysis of New Rural Financial Model under the Background of Internet +

In this paper, through literature review and theoretical analysis, we re-clarify the relationship between traditional financial enterprises and Internet financial enterprises in the development of financial model, considering the total loan, interest rate, income distribution rate, cooperative costs and other factors, so as to build a mathematical model, and use evolutionary game theory, numerical analysis. And the evolutionary game phase diagram method is used to measure the competition and cooperation decision between the traditional financial enterprises and the Internet enterprises, so as to find out what factors affect the choice of competition and cooperation strategy and how much influence the decision-making of enterprises, and put forward a general model. Furthermore, considering the expansion model that the variable cooperative cost varies with the size of the selected strategy part, a two-dimensional dynamic system is constructed which is in line with the actual situation and the new financial development strategy. Then the parameters are assigned according to different situations to verify the results. Finally, according to the results, we put forward optimization proposals for different enterprises. This is not only conducive to enriching and improving the theoretical system of the new type of finance, but also to guiding enterprises to a favorable direction of development.
