Abstract: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.
