回收质量不确定下的竞争性闭环供应链政策机制研究

本文主要探讨了回收质量不确定下的竞争性闭环供应链的政府政策机制，建立了4种情形下的竞争性闭环供应链分散式决策模型，研究了3种政策机制对闭环供应链回收率、总碳排放量和制造商利润的影响，模型由两个制造商和一个第三方回收商构成。结果表明：回收率和制造商利润受到回收质量的影响，存在最佳回收质量系数使回收率最高以及制造商总利润最高，最佳回收质量系数受到碳税的影响；补贴与碳税相结合机制更能有效的引导回收、降低总碳排放量以及激励一般制造商进行再制造。最后，通过算例分析进行了验证。

Research of Policy on Competitive Closed-loop Supply Chain Based on Quality Uncertainty

Thispaper discusses government's policy mechanism for competitive closed-loop supply chain which takes recycling quality into consideration,establishes a decisionmodel of closed-loop supply chain in four cases and studies effects of three distinguishable policy mechanisms on recovery rate of closed-loop supply chain,total carbon emissions and profits of manufacturers.The model consists of two manufacturers and one third-party collector.The results indicate that,recovery rate and profits of manufacturers,both of which are influenced by recycling quality,can be maximized by the optimal recycling quality coefficient which is only affected by carbon tax.Moreover,under themechanism of subsidy combined with carbon tax,recycling can be effectively guided,total carbon emissions decreased and total profits of closed-loop guaranteed.Finally,the analysis is verified by an example.
