基于产品替代的利他型低碳供应链协调研究

The Coordination Research of Altruism Low-carbon Supply Chain Based on Product Substitution

针对产品替代情形下低碳供应链协调问题,考虑零售商利他行为偏好,建立完全自利型和零售商利他型决策模型,探讨零售商利他偏好、消费者对产品碳减排量的敏感度和替代产品价格敏感度对决策变量及协调性的影响。结果表明,利他型零售商在一定范围内通过降低单位低碳产品的利润来提高产品销量,提升消费者环境质量的敏感度,实现低碳供应链良性循环,消费者对产品碳减排量的敏感度越高,供应链整体利润越大。

Aiming at the problem of low-carbon supply chain coordination in the case of product substitution,this paper takes the retailer's altruistic behavior preferences into consideration,and establishes a completely self-interested decision model and a retailer's altruistic decision model.The influence of retailer's altruistic preference coefficient,consumers'sensitivity to product carbon emission reduction and substitute product price sensitivity coefficient on decision variables and coordination are discussed.The results show that:(1)altruistic retailers can increase product sales by reducing the profit per unit of low-carbon products within a certain range;(2)improving consumers'sensitivity to environmental quality can realize a virtuous cycle of low-carbon supply chain;(3)the higher the sensitivity of the product's carbon emission reduction,the greater the overall profit of the supply chain.
