基于区块链技术的医药供应链信息共享行为博弈研究

Research on the Game of Pharmaceutical Supply Chain Information Sharing Behavior Based on Blockchain Technology

信息不对称是阻碍供应链整体效率的主要因素。针对医药供应链缺乏信任的问题,建立医药供应链各节点信息共享演化博弈模型,分析各因素对博弈三方策略选择的影响并使用MATLAB进行仿真验证。研究表明,区块链技术有利于降低信息共享的成本和风险,建立科学合理的奖惩制度,且信息共享激励系数和惩罚系数正向影响医药供应链信息共享策略,信息共享成本和风险系数负向影响信息共享策略。基于研究结论,为提高医药供应链信息共享水平提出对策建议。

Information asymmetry is the main factor that hinders the overall efficiency of the supply chain.To address the problem of lack of trust in the pharmaceutical supply chain,an evolutionary game model of information sharing in each node of the pharmaceutical supply chain is established,and the influence of each factor on the strategy choice of the three parties of the game is analyzed and validated by simulation using MATLAB.The study shows that the blockchain technology can help reduce the cost and risk of information sharing and establish a scientific and reasonable reward and punishment system,and the incentive and punishment coefficients of information sharing positively affect the information sharing strategy of pharmaceutical supply chain,while the cost and risk coefficients of information sharing negatively affect the information sharing strategy.Based on the conclions,the suggestions for improving the information sharing level of pharmaceutical supply chain are put forward.
