基于政府不同补贴模式下的供应链碳减排策略与协调

考虑消费者低碳偏好和政府对制造商的不同碳减排补贴模式，构建了不同碳减排补贴模式下的供应链模型，根据协调条件给出了相应的契约形式及参数.通过对供应链模型的求解，得到了不同碳减排补贴模式下的最优碳减排率和最优订货量.数值分析结果表明：在两种不同补贴模式下，碳减排补贴比例的变化对供应链的最优碳减排率、订货量及期望利润的影响是有较大差异的，而且在碳减排补贴比例相同时，不同碳减排补贴模式下的供应链最优碳减排率、最优订货量、期望利润以及政府给予制造商的碳减排补贴费用也是完全不同的，进而可为政府碳减排补贴政策制定及供应链碳减排优化提供科学的决策依据.

Carbon reduction strategy and coordination of supply chain under different government subsidy modes

Considering low carbon consumer preferences and different government subsidy modes to manufacturers carbon reduction， supply chain models were established under the different subsidy modes， with the contract form and contract parameters of supply chain coordination given. The optimal order quantity and the optimal carbon reduction rate were determined under the different government subsidy modes. The numerical results show that the impacts of the optimal order quantity， the optimal carbon reduction rate and the profit of the supply chain under different government subsidy modes were different At the same proportion of carbon reduction subsidy， the optimal order quantity， the optimal carbon reduction rate ， the profit of the supply chain and government subsidy cost were also different under the two kinds of carbon reduction subsidies. The conclusion provided scientific decision basis for the government subsidy policy to reduce emissions and carbon reduction optimization of supply chain.
