低碳约束与产品替代率情形下的供应链策略

摘要

考虑低碳约束与产品替代率的情形下,设计一个订货量受定价影响的参数为变量的二级供应链模型;利用Stackberg博弈理论,对比分析标准产品、绿色产品和替代产品在有无碳限额交易政策下的集中渠道和分散渠道的供应链最优订货量和最优定价,进而得到最优利润和碳排放量.结果显示:渠道结构对经济和环境的表现都有显著影响,整合的供应链能带来更多利润,分散的供应链碳排放量更低.因此,政策制定者要制定有效的碳排放控制政策;企业要在注重节能环保的同时更好地利用产品差异化战略,才能实现市场经济和社会环境的持续稳定发展.%Considering a two-stage supply chain model with variables whose order quantity is affected by pricing, using the Stackberg game model, we compare the centralized channels of standard products, green products and alternative products under a carbon-free quota trading policy and the supply chain of decentralized channels, the optimum order quantity and optimal pricing to get the best profits and carbon emissions.We use examples to verify the feasibility of the model and calculate the impact of three product changes on the supply chain profits, showing that enterprises should make better use of product differentiation strategy to achieve sustained and stable development while focusing on energy saving and environmental protection.
