Abstract: By taking a two-stage supply chain consisted of a single manufacturer and a single retailer as the objective,the profit model of two-stage supply chain under both wholesale price contract and revenue-sharing contract with/without carbon reduction technology were researched.The influence of carbon reduction rate,carbon tax and unit product's carbon emission on players'order quantities,profits,and contract parameters was discussed.The results showed that an optimal carbon emission reduction rate that made the players'profits achieve a Pareto improvement was existed.The optimal emission reduction rate was positively correlated with carbon tax and negatively correlated with per unit carbon emission.The revenue-sharing contract could effectively coordinate the supply chain with/without carbon emission reduction technology.In addition,the revenue-sharing parameters'scope and interval bounds were both in negative correlation to carbon tax and unit carbon emission.Moreover,the relationship between revenue-sharing parameters and carbon reduction rate was the same as the relationship between carbon reduction rate and incremental profits.

摘要： 以单生产商和单零售商组成的两级供应链为研究对象,构建了生产商采用碳减排技术前后两级供应链的收益模型,探讨了减排率、碳税及单位碳排放量对订货量、收益和契约参数的影响。结果表明:存在最优的碳减排率,使得链上成员的收益获得Pareto改进;最优减排率与碳税正相关、与单位碳排放量负相关。收益共享契约能有效地协调采用碳减排技术前后的供应链,收益共享系数区间的上下界及范围均与碳税和单位碳排放量负相关,与减排率的关系同减排率与收益增量的关系一致。
