考虑参照价格效应和公平关切的低碳供应链决策研究

Low-Carbon Supply Chain Decision-Making Considering Reference Price Effect and Fairness Concern

信息时代,消费者很容易得到产品的参照价格,参照价格效应在消费者的购买行为中发挥着重要作用。碳税政策下,在供应链中考虑制造商的减排投资,分别构建了无公平关切、零售商公平关切和制造商公平关切的三种低碳供应链模型,研究三种情形下的最优决策问题。结果表明:三种情形下,产品价格、减排投资率与参照价格效应的关系取决于参照价格的大小,只有当参照价格高于某一临界值时,产品价格、减排投资率与参照价格效应正相关;零售商公平关切时,产品价格和减排投资率与公平关切系数负相关,始终小于无公平关切时的产品价格和减排投资率;制造商公平关切时,产品价格和减排投资率与公平关切系数正相关,且始终大于无公平关切时的产品价格和减排投资率。以上结果对制造商的减排投资和企业的公平关切行为均有重要实践意义。

In the information age,consumers can easily get the reference price of products,and the reference price effect plays an important role in consumers’purchase behavior.Under the carbon tax policy,considering the emission reduction investment of the manufacturer in the supply chain,this paper studies optimal decision-making issues in three situations,and constructs three kinds of low carbon supply chain models respectively concerning no fairness concern,the fairness concern of the retailer and the fairness concern of the manufacturer.The results show that the relationship between prices of products,emission reduction investment rate and reference price effect depend on the reference price.Only when the reference price is higher than a certain critical value,the prices of products,emission reduction investment rate and reference price effect are positively correlated.When the retailer has fairness concern,the prices of products and emission reduction investment rate are negatively related to the coefficient of fairness concern,and are always smaller than those when there is no fairness concern;when the manufacturer has fairness concern,the prices of products and emission reduction investment rate are positively correlated with the coefficient of fairness concern,and are always greater than when there is no fairness concern.The above results have important practical significance for the emission reduction investment of the manufacturer and the fairness concern behavior of enterprises.
