政府补贴策略对二手产品闭环供应链的影响研究

Research on the Influence of Government Subsidy Strategies on the Closed-loop Supply Chain of Second-hand Products

废旧产品的回收再制造是发展循环经济的重要途径,有利于实现资源的合理配置并产生经济效益。构建单一制造商、零售商和互联网回收平台参与的闭环供应链系统,通过对比无政府补贴、政府补贴制造商和政府补贴回收平台三种策略效果的差异性,探讨互联网回收平台对部分回收产品进行翻新再售的情形下,政府补贴对二手产品闭环供应链决策的影响。结果表明:政府补贴始终能够引导回收平台提高回收价格并扩大制造商的再制造规模;政府补贴回收平台策略下新产品和二手产品的市场价格都降低,且闭环供应链整体利润和社会福利均最高,但制造商的利润会随补贴增加而减少。基于此,可以设计补贴协调机制,使制造商利润在一定分配比例范围内随政府补贴增加而增加,实现供应链协调。

Recycling and remanufacturing of waste products is an important way to develop circular economy,which is conducive to the rational allocation of resources and economic benefits.Considering the construction of a closed-loop supply chain system composed of a single manufacturer,retailer and internet recycling platform,by comparing the differences of the effects of no subsidy,manufacturer subsidy and recycling platform subsidy,this paper discusses the impact of government subsidy on the closed-loop supply chain decision of second-hand products when the Internet recycling platform renovates and resells some recycled products.The results show that government subsidies can always guide the recycling platform to increase the recycling price and expand the remanufacturing scale of manufacturers;Under the subsidy strategy of recycling platform,the market prices of the two products are reduced,and the overall profits and social welfare of the closed-loop supply chain are the highest,but the profits of manufacturers will decrease with the increase of subsidies.Based on this,the subsidy coordination mechanism is designed to make the manufacturer s profit increase with the increase of government subsidy within a certain distribution proportion,so as to realize supply chain coordination.
