Research On The Game Relationship Of Supply Chain Financial Subjects From The Perspective Of Industrial Internet

"Difficult financing" and "expensive financing" have become huge fetters restricting the development of small and medium-sized enterprises.In the Internet era,the transformation of information technology promotes the transformation and upgrading of the traditional industrial system,and creates new management,service models and industrial forms.The concept of "Industrial Internet" emerges at the historic moment.Under the background of industrial Internet,the derivation and development of supply chain finance have become a strategic approach to solve the financing dilemma of SMEs.However,driven by their respective interest goals,the change of the relationship between the participants in supply chain finance is a dynamic game process,w-hich will be affected by various factors,and it is difficult to ensure the long-term stability of supply chain finance.This paper built the platform type of core enterprise leading financial services,industrial Internet service platform in order to achieve supply chain by using evolutionary game method to explore the platform builder platform type core enterprise and bilateral participation group game model between financial institutions,small and medium-sized enterprises,analyzes the supply chain financial participation main body dynamic game relationship and evolutionary stable strategy,in order to achieve supply chain financial health works provide some useful thinking.Based on previous studies,this paper discusses the following contents:1.From the Angle of industry to the Internet,the Internet platform model of core enterprise leading industry service platform frame model,a clear definition of supply chain finance main mainly related to game,and select the platform builder platform type core enterprise and bilateral market to participate in the group supply chain external financial institutions,supply chain internal members small and medium-sized enterprises as the breakthrough point and analyze the dynamic game relation between the supply chain finance main body and its operation strategy choice.2.Use evolutionary game theory to build the dynamic evolutionary game model between platform core enterprises and financial institutions,establish the duplicate dynamic equation and the income payment matrix of game players,and conduct stable equilibrium analysis.Research on the evolutionary speed of platform-based core enterprises and financial institutions,the net benefits brought by the cooperation,the net benefits of the two parties from the collaboration,and the initial cooperation probability,shows that the difference between the net income obtained by the two parties from the supply chain financial cooperation and the net income obtained by when the other party choose to cooperate and they choose to withdraw from the cooperation strategy is the key factor for the strategic choice and evolutionary state of both parties.3.Using the research and analysis method of evolutionary game theory,the dynamic evolutionary game model of action strategy between small and medium-sized enterprises and platform core enterprises is constructed,and the duplicate dynamic equation and the income payment matrix of the game subject are established for stable equilibrium analysis.Under the operating mechanism of the constructed industrial Internet service platform,the evolutionary and stable trajectory of game equilibrium between small and medium-sized enterprises and platform core enterprises is explored by means of numerical simulation,such as demand of small and medium-sized enterprises,membership rate,benefit parameter of platform effect,effort cost parameter and opportunity cost.
