考虑碳排放差异的闭环供应链补贴机制研究

Study on Subsidy System for Closed-loop Supply Chains with Carbon Emissions Difference Considered

考虑到再制造碳排放差异闭环供应链的决策与补贴问题,运用stackbelberg博弈理论,研究了补贴机制对闭环供应链均衡价格与节点企业利润的影响,探讨了政府补贴力度、碳排放差异与制造过程总碳排放量之间的关系。研究表明:补贴机制能有效提升回收率与节点企业利润,降低节点企业决策价格与单位产品平均碳排放量,并能根据补贴力度、碳排放差异与碳排放总量之间的关系,制定合适的补贴制度,在提高再制造水平的同时控制总碳排放量。最后通过数值算例验证了上述结论。

In this paper, we used the Stackelberg game theory to study the influence of the subsidy system on the equilibrium price and node profit of closed-loop supply chains, and discussed the relationship between the intensity of government subsidy, difference in carbon emissions and the total carbon emissions in the manufacturing process, through which we reached some useful conclusions. At the end, we verified the conclusions made through a numerical example.
