Research On The Model And Game Analysis Of Accounts Receivable Pledge In Supply Chain Based On Blckchain Technology

The pledge mode of supply chain accounts receivable is helpful to alleviate the financing difficulties of small and medium-sized enterprises in the supply chain.By pledging accounts receivable documents to financial institutions,the capital flow is revitalized,and the smooth operation of the whole supply chain finance is promoted.However,due to the serious information asymmetry in supply chain finance,it is difficult to realize multi-level credit circulation,which has always restricted the development of accounts receivable pledge model.With the rapid development of financial technology,blockchain technology has attracted much attention in recent years,which plays an important role in promoting the innovation of accounts receivable pledge model,and is expected to promote supply chain finance to break through the bottleneck and achieve transformational development.Based on blockchain theory,supply chain finance theory and game theory,this paper conducts in-depth literature research on supply chain finance,accounts receivable pledge mode,blockchain technology and its game in the field of supply chain finance,and puts forward the hypothesis of supply chain finance accounts receivable pledge mode based on blockchain technology;Then,from two aspects of qualitative analysis and quantitative analysis,this paper studies how blockchain technology can empower supply chain financial services.Firstly,through literature research and qualitative analysis,this paper analyzes the four aspects of blockchain technology in promoting the circulation of information resources,cross-subject cooperation and coordination,multi-level credit transmission and risk control management ability of accounts receivable pledge model;In view of the development dilemma of supply chain finance,this paper analyzes the mechanism of blockchain technology in solving information asymmetry,realizing credit transfer of core enterprises and preventing supply chain financial risks,which provides effective enlightenment for the innovation of supply chain accounts receivable pledge model.Secondly,through the quantitative evolutionary game model,this paper analyzes the evolutionary decision-making of the decision-makers of the supply chain accounts receivable pledge model,explores the cooperation between core enterprises and small and medium-sized enterprises,and the audit and supervision of the loan application of small and medium-sized enterprises by financial institutions,and analyzes the influence of the change of dialysis parameters on the evolution of decision-makers under different conditions;Moreover,by introducing relevant parameters such as block benefit and penalty cost,this paper discusses the influence of blockchain technology on the model,the decision-making changes and evolution paths of all parties,and reveals the evolution law under the background of blockchain technology.The conclusion is that blockchain can bring financing advantages to small and medium-sized enterprises.By comparing the equilibrium point difference between blockchain technology and traditional supply chain accounts receivable pledge model,it is found that the use of blockchain brings efficiency benefits,credit benefits and additional default costs,and increases the benefits of small and medium-sized enterprises,core enterprises and banks,thus achieving good cooperation among the three parties and healthy operation of the supply chain.According to the model results,suggestions are made to supply chain enterprises,financial institutions and government departments respectively.
