Research On Co-operation And Share Of Emission Reduction Costs Of Automotive Supply Chain Under Different Carbon Emission Policies

Greenhouse gases,mainly CO₂,are increasingly endangering human living environment.Therefore,all countries in the world have adopted corresponding carbon emission policies to meet the challenge of greenhouse effect,among which carbon tax and carbon emission are the main ones.As a major emitter of greenhouse gases,China first proposed a carbon tax policy in 2009.However,due to the insufficiency of China’s current industrial structure and other characteristics,enterprises that rely heavily on carbon emissions cannot afford it.Therefore,since 2011,China has successively launched seven carbon trading pilot projects in seven provinces and cities across the country,and achieved rich results.China will officially launch a carbon trading market for the country’s power generation industry in 2017,symbolizing that it is not far from building a carbon trading market covering more industries.With the upgrading of China’s industrial structure,carbon tax,as an important means of global emission reduction,will soon become a focus of attention.As a pillar industry of China’s national economy,the automobile industry not only helps China’s economy,but also brings a large amount of carbon dioxide emissions.Therefore,the low-carbon and sustainable development of the automobile industry is of great significance for China to achieve the emission reduction target.Carbon dioxide produced by manufacturers and consumers in the process of production and use are two important sources of automobile carbon emissions.No matter the use link or the production link of low-carbon emission reduction behavior,manufacturers need to invest more emission reduction capital.Consumers’desire for low-carbon environmental protection also urges manufacturers to invest in research and development to produce low-carbon and energy-saving vehicles.However,under the constraint of carbon emission policy,it is not enough for individual enterprises to make their own efforts in carbon emission reduction.Only through close cooperation among enterprises in the automobile supply chain can the final carbon emission reduction target be effectively achieved.Based on this,this paper respectively in the two kinds of carbon emissions,carbon trading and carbon tax policies,government subsidies for consumers factors,analyzes the different emission reduction cost sharing cooperation method（decentralized decision making,low carbon technology research and development to share cooperation,promote share cooperation and mutual responsibility cost）emission reduction of the whole supply chain node enterprise and supply chain strategy.Finally,the optimal cost-sharing method and emission reduction strategy are found for the nodal enterprises of the low-carbon automobile supply chain,so as to achieve the pareto optimal emission reduction and profit of the enterprise and the supply chain as a whole.Study found that both carbon trading policy and tax policy,the cost of each arm is better than the other three cooperation ways of cooperation,cooperation more than cooperation achieve corporate profits and the double increase of reduction,low carbon technology research and development at the same time share cooperation can increase more than promotion points but cooperation manufacturers of emission reductions,the former profits while a certain condition will be greater than the latter;For manufacturers and the supply chain as a whole,carbon trading can increase profits and reduce emissions more than a carbon tax under different sharing schemes.
