不足之处是,文中在考虑供应链纵向减排合作的动态策略时,并没考虑到政府政策对企业间减排合作的影响,随着政府对企业碳排放量的限制和碳交易市场的出现,供应链企业间长期纵向减排合作将会出现新的契机和问题;供应链纵向减排合作除了涉及制造商和供应商之间的合作,还涉及到制造商和下游零售商之间减排和低碳推广的合作,因此本论文仅仅是研究供应链企业减排合作动态策略的开端,我们将在后续进行更深入研究。此外,文中为了简化模型,假设制造商和供应商产品的边际利润为常量,而实际中在非合作情形下,供应链节点企业之间的产品交易价格常常是供应链运营的决策变量,因此在现有模型中引入批发价格等决策变量,也是我们未来值得研究的问题之一。
This study considers that reduction rate can affect the cooperation of carbon emission reduction between enterprises in product demand, and the upstream and downstream supply chains. In addition, this study assumes that demand has a linear relationship with carbon emissions. Vertical cooperation on carbon emission reduction is discussed based on a differential game in a two-stage supply chain consisting of a single supplier and a single manufacturer.
In the first part, we analyzed the Stackelberg game scenario in which manufacturer is a leader and supplier is a follower in the supply chain with the goal of reducing carbon emissions. In addition, we built the Stackelberg differential game models and solved this differential game by using the HJB equation to obtain feedback equilibrium strategy, the optimal function of profit about manufacturer and supplier, and an optimal trajectory for carbon emissions of product.
In the second part, we analyzed the other scenarios in which vertical cooperation between manufacturers and suppliers about emission reduction was presented. Moreover, we attained a feedback equilibrium strategy of manufacturer and supplier and the optimal function of profit about the entire supply chain and optimal trajectory for carbon emissions of product.
After comparing the two feedback equilibrium strategies, this study proposed that vertical cooperation strategies about emission reduction could improve the emissions of product, and the profit of supplier and manufacturer. The entire supply chain system is higher than non-cooperation supply chains because of the coordination among enterprises in the supply chain.
