基于区块链技术的农产品供应链演化博弈研究

Research on evolutionary game of agricultural products supply chain based on blockchain technology

为确保加入区块链的农产品供应链主体遵循协议共享初始真实信息,针对农产品供应链信息不对称、缺乏信任等问题,搭建了区块链技术的农产品供应链框架。对采用区块链技术的农产品供应链参与主体是否守约构建演化博弈模型,分析各主体遵循区块链节点共享初始真实信息的影响因素。使用MATLAB进行仿真,结果表明,当加入区块链的信任程度、协同收益、激励和惩罚提高、风险系数变低,农产品供应链参与主体更倾向于遵守区块链协议守约,这些因素影响区块链节点下参与的主体策略选择。明确区块链技术运用在农产品供应链的可行性,可为各参与方提供对策,提高农产品供应链的整体效率。

In order to ensure that the participants of the agricultural supply chain that joined the blockchain follow the agreement to share the initial true information,this paper built the agricultural supply chain framework of block chain technology to solve the problems of information asymmetry and lack of trust in the agricultural supply chain.It built an evolutionary game model for whether the participants of the agricultural supply chain adopting block chain technology kept their promises,and analyzed the factors that influenced the initial real information shared by each entity following the blockchain node.This paper used MATLAB for simulation,the results show that when the trust level,synergistic benefits,incentives and punishments of joining the blockchain increase,the risk coefficient becomes lower,the participants in the agricultural product supply chain are more inclined to abide by the blockchain agreement,these factors affect the strategic choice of participants under the blockchain node.This paper clarifies the feasibility of applying blockchain technology to the agricultural product supply chain,provides countermeasures for all participants,and improves the overall efficiency of the agricultural product supply chain.
