Supply Chain Contract Arrangements of Carbon Abatement with Consumer Preferences

With the global climate continues warming, carbon emissions become the global focus. How to design the contract of low-carbon supply chain is an important research direction. Our goal in this paper is to construct supply chain decision model under carbon tax. And we build the demand distribution function including consumer characters which is more in line with the reality of the actual retailer operations. Through numerical analysis using Matlab software， we find that carbon emissions allocation coefficient does not affect the optimal profits of suppliers and retailer under wholesale price contract; Supply chain enterprise could gain more profit through the carbon emissions collaborative, choosing reasonable carbon emissions levels.
