摘　　要：信息不对称引发的成本过高问题使得平台型供应链金融发展受到一定限制。针对存在的成本风险问题,以平台型供应链金融融资业务为研究对象,对影响参与主体决策的因素进行分析,分别构建传统情形下与区块链驱动下中小企业、核心企业和金融机构的三方演化博弈模型,探究各参与主体的均衡选择,对比区块链引入前后博弈各方的收益,并结合实际利用Matlab进行数值仿真模拟。研究发现:在平台型供应链金融融资系统引入区块链后,将会强化各参与主体向博弈的最佳均衡点(融资,担保,参与)靠拢,使得融资博弈系统达到帕累托最优状态的条件有所放宽,平台型供应链金融业务更易完成,供应链金融融资得到了帕累托改进。因此,提出搭建基于区块链的供应链金融服务平台,运用区块链的创新特征提高网络协同效率,降低各类参与成本,促进平台型供应链金融的稳定发展。The problem of a high cost caused by information asymmetry makes the finance development of the platform-based supply chain limited to a certain extent.In view of the existing cost risks,this paper takes the financing business of the platform-based supply chain as the research object,and analyzes the factors affecting the decision-making of the participants.Under the traditional situation and driven by the blockchain,we build a three-party evolutionary game model for small and medium-sized enterprises,core enterprises and financial institutions respectively.We explore the balanced choice of each participant,compare the benefits of the game parties before and after the introduction of the blockchain,and carry out numerical simulation using Matlab in accordance with practice.The research results show that,after the introduction of the financial system of the platform-based supply chain into the blockchain,all related participants will be instructed to move closer to the optimal equilibrium point of the game(financing,guarantee,participation),so that the conditions for the financing game system to reach Pareto optimality are easily met.At the same time,the financing business of the platform-based supply chain is easier to complete,and the supply chain finance has been Pareto improved.Therefore,this paper proposes to build a supply chain financial service platform based on the blockchain,uses the innovative features of the blockchain to improve network collaboration efficiency,reduces various participation costs,and promotes a stable finance development of platform-based supply chain.
