政府补贴下双渠道闭环供应链回收渠道的选择研究

Research on Recycling Channel of Dual Channel Closed Loop Supply Chain Under Government Subsidy

在以制造商为主导的双渠道供应链中,政府制造商进行补贴的前提下,分别建立了三种不同的回收模型:制造商回收、零售商回收和制造商和零售商混合竞争回收,并研究不同模型的最优决策得出结论,最后进行仿真验证.研究表明:制造商垄断回收时,供应链各成员的收益都是关于回收价格敏感系数的增函数;零售商垄断回收时,制造商和零售商的利润降低,此时整个供应链的回收量是制造商回收时的一半;竞争回收模式下,当回收价格敏感系数增大时,制造商利润减小,零售商利润增大,供应链利润先增大后减小,制造商的回收量大于零售商的回收量.在三种模型下,回收价格敏感系数较小时,制造商回收模式最优;回收价格敏感系数较大时,竞争混合回收模式最优.

In the dual channel supply chain dominated by manufacturers,under the premise of government subsidies to manufacturers,three different recycling models are established:Manufacturer recycling,retailer recycling and mixed competitive recycling between manufacturers and retailers.The optimal decisions of different models are studied,and the conclusions are drawn.Finally,the simulation is carried out to verify them.The research shows that when the manufacturer monopolizes recycling,the income of each member of the supply chain is an increasing function of the price sensitivity coefficient of recycling;When retailers monopolize recycling,the profits of manufacturers and retailers are reduced.At this time,the recycling volume of the whole supply chain is half of that of manufacturers;In the competitive recovery mode,when the recovery price sensitivity coefficient increases,the manufacturer’s profit decreases,the retailer’s profit increases,the supply chain profit first increases and then decreases,and the manufacturer’s recovery is greater than that of the retailer.Under the three models,the manufacturer’s recycling mode is the best when the recycling price sensitivity coefficient is small;When the recovery price sensitivity coefficient is large,the competitive hybrid recovery model is the best.
