Blockchain Technology-based Game Analysis Of Supply Chain Accounts Receivable Financing

Small and medium-sized enterprises(SMEs)play an important role in promoting economic and social development,but the difficulty of financing has always restricted the development of SMEs.Although the traditional supply chain finance has alleviated the problem of difficult financing for SMEs,it still cannot fully play its role,mainly because of the high information cost of enterprises due to information asymmetry;banks and other financial institutions are more sensitive to credit risks.The decentralized,tamper-evident and traceable characteristics of blockchain technology provide new ideas to solve the dilemma of supply chain finance.In this context,this paper explores its impact on supply chain finance from the perspective of information sharing at the level of blockchain technology.Taking accounts receivable pledge financing model as the entry point,this paper explores the relationship among node enterprises in accounts receivable financing model based on blockchain technology.This paper firstly constructs a traditional supply chain finance accounts receivable game model for analysis,and then on this basis,from the blockchain technology level,introduces parameters such as information sharing degree and blockchain penalty coefficient to construct an evolutionary game model of accounts receivable based on information sharing of blockchain technology,discusses the evolutionary stabilization strategies of SME nodes and core enterprise nodes,explores the influence of key parameters on evolving systems,and finally numerical simulation is conducted by Matlab software to verify the validity and feasibility of the model and give relevant management suggestions.The main conclusions are as follows:(1)Increasing the values of information sharing degree,incentive coefficient,and blockchain penalty will make node enterprises tend to choose the compliance strategy;increasing the blockchain access and maintenance cost will make node enterprises tend to choose the default strategy.(2)There is a threshold value for the information sharing degree of nodal enterprises,and when it reaches a certain value,both sides of the game are more inclined to keep the contract and thus better cooperate in financing;the information sharing degree and the blockchain penalty coefficient interact with each other to generate positive feedback,and increasing the information sharing degree can enhance the binding force of blockchain penalty and promote the benign development of financing activities.(3)In general,SMEs are more sensitive to various influencing factors and more inclined to keep their contracts and actively share information than core enterprises.When information sharing is low and block linking is more costly to access and operate,core firms are more sensitive to parameters and more inclined to default.This paper adopts evolutionary game model construction,numerical simulation analysis and other research methods.The main innovation is to adopt the method of evolutionary game theory and explore the influence on the receivables financing model from the perspective of information sharing of blockchain technology.This paper based on the analysis of key influencing factors such as information sharing degree,information sharing incentive coefficient and blockchain access and operating costs,introduced the interaction between blockchain penalty coefficient and information sharing degree,and used the mechanism of combining blockchain technology and information sharing to improve the problem of difficult financing for SMEs,and made relevant suggestions for supply chain finance accounts receivable financing business.
