摘　　要：考虑制造商的生产过程和运输商的运输过程都产生碳排放,建立一条由制造商、运输商与零售商组成的三级供应链,运用Stackelberg博弈和Nash博弈分析三级供应链在碳税政策下的最优碳减排、产品定价、系统利润与社会福利等关键指标的状态.讨论了四种情形:1)碳减排领域和产品定价领域都不合作的无合作决策;2)碳减排领域合作但产品定价领域不合作的局部合作决策Ⅰ;3)产品定价领域合作但碳减排领域不合作的局部合作决策Ⅱ;4)碳减排领域和产品定价领域都合作的全面合作决策.研究表明,随着供应链成员之间合作程度的逐步加深,供应链系统的经济效益(系统利润)、社会效益(产品定价和社会福利)、环境效益(最优碳减排量)越来越优.同时,研究了碳税税率变动对最优碳减排和产品定价决策的影响,推导了供应链协调契约中成员企业利润分配比例的有效区间.最后,通过一个数值算例对所给的部分定理与结论进行验证.This study constructs a three-echelon supply chain composed of a single manufacturer,a single transporter and a single retailer.Both production and transport produce carbon emissions.The government imposed a carbon tax on carbon producers.The study applies Stackelberg game and Nash game to research the state of key indicators such as the optimal carbon emissions reduction,pricing and social welfare.The four scenarios were designed as follows:1) Non-cooperative decision-making,in which neither carbon emission reduction cooperation nor pricing cooperation takes place;2) local cooperative decision-making I,in which only cooperation in the field of carbon emission reductions takes place;3) local cooperative decision-making II,in which merely cooperation in the field of pricing without cooperation in the field of carbon emission reductions takes place;4) overall cooperative decision-making,in which both cooperation in the field of carbon emission reductions and cooperation in the field of pricing take place.The result shows that with the deepening of cooperation among the supply chain members,the economic benefits(the system profit),social benefits(the pricing and the social welfare) and environmental benefits(the optimal carbon emission reduction) of the supply chain system are getting better and better.The influence of carbon tax rate changes on the optimal carbon emission reductions and pricing decision is studied,and the effective interval of profit distribution ratio of member enterprises in the supply chain coordination contract is deduced.Finally,a numerical example is given to verify some theorems and conclusions.
