双渠道低碳供应链合作减排优化决策

Optimization of cooperative emission reduction in dual channel low carbon supply chain

基于供应链制造商的高碳减排成本,考虑零售商为制造商投资进行合作减排,在消费者低碳偏好下,建立制造商和零售商之间的博弈模型,对制造商是否减排、零售商是否投资时的供应链最优决策进行对比。研究发现,消费者对低碳产品的偏好行为可以使制造商和零售商的利润都有所增加,但是会出现零售商"搭便车"现象,而零售商投资减排后能消除这一现象。碳减排量和线上线下产品价格都会随零售商投资比例的增加而增加,当零售商投资达到一定比例时,可以实现制造商和零售商双方的利益最大化。

Based on the high carbon emission reduction cost of supply chain manufacturers,considering the retailer s investment for manufacturers to carry out cooperative emission reduction,a game model between manufacturers and retailers is established under the low carbon preference of consumers.The optimal decision-making of supply chain are compared under the circumstances of whether manufacturers reduce emissions and whether retailers invest.It is found that consumers preference for low-carbon products can increase the profits of both manufacturers and retailers,but there will be more profits for retailers than for manufacturers,which can be eliminated after investment of retailers.Carbon emission reduction and online and offline product prices will increase with the increase of retailer investment proportion.When the retailer s investment reaches a certain proportion,it can maximize the benefits of both manufacturers and retailers.
