基于区块链技术的政府采购合同融资博弈分析

Game Analysis of Government Procurement Contract Financing Based on Blockchain Technology

针对中小企业融资难以及供应链金融现有的信用问题,将区块链技术运用进财政部提出的政府采购合同融资模式中。从供应链业务层面出发,构建政府采购部门、中小企业和银行的三方博弈模型,对各主体的决策进行分析;从区块链技术层面出发构建演化博弈模型,对链上各节点的选择进行分析。通过MATLAB软件进行仿真实验,验证了利用激励相容理论将区块链技术运用进政府采购合同融资模式中的可行性和准确性,为该模式中的各参与主体提供对策建议。

In view of the financing difficulties of small and medium-sized enterprise and the existing credit problems of financial supply chain,the block chain technology is applied to the financing mode of government procurement contract of the Ministry of Finance.From the supply chain business aspect,the tripartite game model of government procurement departments,small and medium-sized enterprises and banks is built,and the decision of the main body is analyzed.From the block chain technology,the evolutionary game model is built and the selection of chain node is analyzed.By MATLAB,the simulation experiments are carried out to verify the feasibility and accuracy of applying block chain technology to the financing mode of government procurement contract on incentive compatibility theory,which can provide countermeasures and suggestions to each participant in the mode.
