链式竞争下基于Hotelling模型的定价与减排决策

摘要

考虑异质产品供应链在不同销售渠道下的供应链竞争情况,构建了基于Hotelling模型的产品定价与减排决策模型.研究发现,在无制造商网络直销渠道的情况下,尽管低碳产品零售价格大于普通产品价格,但低碳产品的市场份额大于普通产品的市场份额;但当制造商开通网络直销渠道后,两种产品传统零售渠道的市场份额相同,低碳产品市场份额随着消费者低碳偏好逐渐增大,普通产品市场份额相应减小.同时,低碳产品制造商在双渠道中的碳减排率高于单渠道的碳减排率.%Considering the market competition between ordinary product supply chain and low carbon product supply chain in both the retail-channel and dual-channel cases,we analyzed the decisions on product pricing and carbon emissions reduction in the supply chains based on Hotelling model.It is shown that the market share of low carbon products is larger than that of the ordinary products in spite of its higher price in the case of the retail-channel.In the case of dual channel,there is no difference of market share between two products in traditional channel.The market share of low carbon product increases (while ordinary product decreases) with the increase of consumer's preference for low carbon.Moreover,the carbon emission reduction of manufacturer in dual-channel is larger than that in retailer-channel.
