Supply Chain Collaborative Strategy Study On Carbon Abatement Considering The Consumer Behavior

The rapid development of industrialization brings the continues warming of global climate, which is seriously impact on human sustainable development; so carbon emissions become the focus of the global attention. The competition between enterprises become between supply chain competition today, how to design the contract of supply chain to realize low carbon supply chain, to approach a coordination and harmonization to environmental and economy is an important research direction of carbon emissions. This is the initial purpose of researching carbon reduction in supply chain management.Applying the theory and method of supply chain contract and Game theory, My goal in this paper is to construct supply chain decision model under carbon tax, strict cap, cap-trade. And we build the demand distribution function including consumer characters.First, we construct the carbon reduction decision model of supply chain under carbon tax system. Comparatively analyzing the supply chain profit level before and after the carbon abatement, studying the influence of the consumer preference to supply chain decisions. Secondly, we construct the carbon reduction decision model of supply chain under strict cap system. And analyzing the influence of different consumer preference or government carbon quota to supply chain coordination. At last, we construct the carbon abatement decision model of supply chain under cap-and-trade. Comparatively analyzing the two cases of fixed and variable carbon abatement level. And analyzing the influence of exogenous variables to supply chain coordination.Basis the model analysis, we did the numerical and sensitivity analysis. The analysis indicated that carbon emissions allocation coefficient does not affect the optimal profits of suppliers and retailer under wholesale price contract; With the consumers preference to low carbon products increased, successful implementation of supply chain carbon reduction can enable the companies get more green, also makes the companies improving market competitiveness. So the Supply chain enterprise could gain more profit through the carbon emissions collaborative, choosing reasonable carbon emissions levels. And we comparatively analyzed the different optimization results of the three systems.
