摘　　要：在区块链的应用背景下,利用需求信息传递过程中的信息熵量化牛鞭效应,以单个零售商和单个制造商所构成的二级供应链为研究对象构建博弈模型,在通用模型求解结果的基础上,探究供应链中主体的利润分配情况.研究发现,区块链技术的引入能够降低零售商的订货量和供应商的生产量,对牛鞭效应具有弱化作用;引入成本分担契约能够使主体双方的区块链应用程度得到协调的同时提升供应链的总利润,虽然获利更多的一方往往是主导方,但跟随的一方至少也能获得保留收益.In the context of the application of blockchain,the bullwhip effect is quantified by the information entropy in the process of demand information transmission.A game model is constructed for the secondary supply chain composed of a single retailer and a single manufacturer.Based on the results of the general model,the profit distribution of the main body in the supply chain is explored.The results show that:the introduction of blockchain technology can reduce the retailer′s order quantity and the supplier′s production volume,and weaken the bullwhip effect.The introduction of cost sharing contract can coordinate the application degree of blockchain between the two parties and improve the total profit of the supply chain.Although the party with more profits is often the leading party,the following party can at least obtain retained earnings.

关 键 词：牛鞭效应 区块链 成本分摊契约 利润分配
