Research On Supply Chain Financial Trust Mechanism And Application Based On Blockchain

As the backbone of China's private economic development,SMEs are currently facing difficulties in financing and expensive financing.Supply chain finance is more tolerant and open to small and medium-sized enterprises,and it provides solutions to the financing problems of small and medium-sized enterprises.However,the current serious lack of trust in the supply chain,asymmetry of information among enterprises,imperfect access to information,and inability to guarantee the reliability of information make it impossible for all parties in the supply chain to cooperate smoothly,and the effectiveness of the supply chain is greatly reduced.As an emerging technology,blockchain is a system composed of credit records and credit record clearing.With its advantages of decentralization,trustlessness,traceability,anonymity,non-tamperability,and smart contracts,it solves many problems well.The issues of mutual trust and benefit distribution between the points are highly compatible with supply chain finance,which can well empower supply chain finance and provide credit supplements for supply chain finance.This paper constructs an evolutionary game model between financial institutions and small and medium-sized enterprises in supply chain finance,puts the blockchain as a parameter into the model,analyzes the game stability by constructing a Jacobian matrix,and uses Matlab software for numerical simulation analysis.Analyze the impact of parameter changes on the evolution of decision-making parties under different conditions,discuss the changes and evolution paths of decision-making by all parties,and reveal the evolutionary law under the background of financial technology,showing that the new financing model of blockchain-based supply chain finance is more important to the traditional supply chain.In terms of financial mode,it is a reasonable credit supplement mechanism,which increases the credit of supply chain finance to a certain extent.Based on the evolutionary game model,this paper constructs a blockchainbased supply chain financial credit system from three aspects: credit storage mechanism,credit sharing mechanism,and credit management mechanism.Under the credit system,cross-border supply chain finance is taken as an example to design Established a cross-border supply chain financial service platform,and explored the integration path of blockchain and supply chain finance.
