摘要
基于碳税政策,构建两级农产品供应链,其中生产商实施低碳减排技术,零售商提供产品保鲜服务。考虑市场需求受减排努力、保鲜努力以及销售价格的影响,运用Stackelberg博弈理论,对比分析供应链成员最优决策及供应链整体利润在集中和分散情形下受减排需求弹性及保鲜需求弹性的影响变化趋势,发现分散情形下的生产商减排努力、零售商保鲜努力以及供应链整体利润均小于集中情形,且与减排需求弹性系数及保鲜需求弹性系数成正比。进而设计契约,发现“成本分担”契约仅能刺激减排,无法实现供应链协调,“双向成本分担-收益共享”契约参数满足一定条件时,能同时激励生产商减排和零售商提升保鲜努力,也能实现帕累托最优。
Based on the carbon tax policy,a two-level agricultural supply chain is constructed,in which manufacturers implement low-carbon emission reduction technologies and retailers provide product preservation services.Considering the influence of emission reduction efforts,preservation efforts and sales prices on market demand,Stackelberg game theory is used to compare and analyze the optimal decisions of supply chain members and the overall profit of the supply chain under the influence of emission reduction demand and preservation demand elasticity coefficients in centralized and decentralized situations.It is found that the emission reduction efforts of manufacturers,the preservation efforts of retailers and the overall profit of the supply chain in a decentralized situation are all lower than those in a centralized one,also,they are proportional to the elasticity coefficients of emission reduction demand and preservation demand.Furthermore,a contract is designed and find that the"cost sharing"contract can stimulate emission reduction only,but can not achieve supply chain coordination;when the parameters of the"bilateral cost sharing-benefit sharing"contract satisfy certain conditions,it can not only stimulate manufacturers to reduce emissions and retailers to improve their preservation efforts,but also realize Pareto optimality.
