零售商减排投资成本分担的分担比例决策

Decision on Sharing Ratio of Emission Reduction Investment Cost by a Retailer

为了研究碳税、碳限额和碳交易三种碳减排政策下供应链减排成本分担契约的分担比例决策及其影响,以减排投资成本分担比例为研究对象,建立了无领导者渠道结构下一个供应商和一个零售商组成的二级供应链博弈模型,探讨了传统消费者市场上零售商参与减排成本分担契约的动机、成本分担契约形成的前提条件、制约因素、减排效果与双方利润占比,并就主要结论进行了数值模拟。研究发现零售商提出的减排投资成本分担契约能够协调供应链的前提条件是碳减排价格不高于阈值,最优分担比例受产品市场需求敏感度、减排投资成本系数和碳排放价格的影响,存在确定的边界。

To study the decision on cost share ratio and its impact of emission reduction in a supply chain under the policies of carbon taxation,carbon quota,cap and trade,we establishes the two-level supply chain game model on tradition consumer market under no leader channel structure made up of a supplier and a retailer,aiming at the retailer＇s motive on joining in a cost share contract,the proposition of a cost share contract agreed by a supply chain＇s both parties,the decision＇s restrictions,the decision＇s emission reduction effect and both parties＇ profit share. Some numerical experiments are done on major conclusions.The study demonstrates that it requires the proposition if the emission reduction cost sharing contract proposed by retailer can coordinate the supply chain,namely the carbon emission price must be lower than some critical value. The cost share ratio is correlated to the market sensitivity coefficient,the emission reduction investment cost coefficient,and carbon emission price,thus it is limited to definite bounds.
