基于区块链的闭环供应链定价及回收策略

Pricing and Recovery Strategy of Closed-Loop Supply Chain Based on Blockchain

考虑区块链技术下新能源汽车闭环供应链定价及回收决策问题,构建制造商和零售商回收模式下链上成员Stackelberg(斯塔克尔伯格)博弈模型。结果表明,随着消费者对绿色产品偏好提升,碳减排努力、链上成员利润及社会福利等均增长;提高梯次利用比例将增加零售商回收模式下零售商利润、两种回收模式下制造商利润及社会福利,尤其引入区块链及制造商回收对社会福利影响显著;采用区块链单位成本满足一定阈值时,采用区块链有利于提升需求量和碳减排努力。

Considering the closed-loop supply chain pricing and recycling decision problem of new energy vehicles under blockchain technology,a Stackelberg game model was constructed for the on-chain members under the recycling modes of manufacturers and retailers.The results show that as consumers’preference for green products increases,carbon emission reduction efforts,profits of chain members,and social welfare increase.Increasing the proportion of laddered utilization will increase retailers’profits under the retailer recycling mode,manufacturers’profits under the two recycling modes,and social welfare,and in particular,the introduction of blockchain and manufacturers’recycling has a significant impact on social welfare.Adopting blockchain is conducive to increasing the quantity of demand and carbon emission reduction efforts when the unit cost of blockchain adoption meets a certain threshold value.
