低碳经济下三级供应链动态减排的微分博弈分析

Differential Game Analysis of Dynamic Carbon Emission Reduction Strategy of Three-Echelon Supply Chain under Low-carbon Economy

在低碳经济的背景下,考虑到碳减排的连续性,引入时间因素,从动态角度将微分博弈的方法应用到三级供应链的减排决策中,构建了由一个供应商、一个制造商和一个零售商组成三级供应链的动态减排决策模型,比较分析在协同状态和非协同状态下产品减排量的变化曲线和供应链利润,同时还得到供应商、制造商和零售商的最优决策及利润。最后,使用算例分析的方法分析了各参数对产品减排量轨迹的影响,所得结论可以为供应商、制造商和零售商的决策提供理论依据。

Against the background of low-carbon economy,considering the continuity of carbon emission reduction,time factor is introduced to the model.This paper applies differential game method to carbon emission reduction decision in a three-echelon supply chain,and constructs a dynamic carbon emission reduction decision model of a three-echelon supply chain consisting of a supplier,a manufacturer and a retailer.It compares the products’carbon emission reduction and the profit of supply chain under coordination and non coordination.The optimal trajectory of products’carbon emission reduction can be found,and the optimal feedback equilibrium strategy of the supplier,the manufacturer and the retailer can be also obtained.Finally,this paper analyzes the impact of related parameters on optimal trajectory of products’carbon emission reduction through a numerical example,and the theoretical basis is provided for long-term emissions reduction strategy of the supply chain.
