税收补贴政策下考虑二手市场电子产品回收供应链成员的博弈策略研究

Recycling supply chain members’strategy for electronic product considering second-hand market under the tax-subsidy policy

考虑由一个制造商、一个回收商及二手市场组成的两层供应链结构,分别构建了仅回收商回收的决策模型、回收商回收与二手市场交易共存的决策模型,基于消费者效用分析了供应链成员的最优产品定价策略,探讨了二手市场的引入对电子产品回收供应链成员决策及税收补贴政策设计的影响。结果显示:在一定条件下,二手市场交易的竞争一方面使消费者在电子产品回收中获益,另一方面也提高了制造商的利润及政府税收补贴剩余。但是,二手市场交易的竞争致使回收商的利润降低,政府可以适当提高对回收商的产品回收补贴来增强回收商的竞争力,降低回收商的利润损失。此外,本文证明了从社会总福利的角度看待开发二手市场是大有裨益的。

Considering the two-echelon supply chain composed of a manufacturer and a recycler,we construct the recycler-recycling decision-making model,recycler-recycling and secondary market transactions coexist recycling decision-making model.Based on consumer utility,we analyze the optimal pricing strategies of supply chain members and discuss the impact of the introduction of the secondary market on recycling supply chain members’strategy for electronic product and the design of the tax-subsidy policy.Our results show that,with the competition of secondary market,consumers can benefit a lot in the process of used electronic product recycling in certain circumstances.In addition,the competition of secondary market is enhanced,the manufacturer’s profit and government’s surplus is improved.Otherwise,with the competition of secondary market,the recycler’s profit is lower,the government can properly improve products’subsidy to strengthen its competitiveness and weaken the loss of the recycler’s profit.Besides,we conclude that from the perspective of total social welfare,the exploiting of secondary market is beneficial.
