碳税政策下闭环供应链定价及减排决策

Pricing and Carbon Reduction Decisions on Closed-loop Supply Chain under Carbon Tax Policy

考虑消费者对新产品和再制造产品的异质需求,构建了制造商和零售商之间的博弈模型,探讨了碳税政策对闭环供应链定价决策的影响;其次,分析了制造商减排投资对生产定价、利润及碳排放的影响。研究表明:制造商可以根据再制造产品的碳排放强度选择四种不同的生产策略;再制造能够实现经济效益和环境效益双赢,但不能抵消碳税对企业利润的影响;制造商投资减排能够在一定程度上缓解碳税和再制造对新产品造成的冲击,使供应链收益增加的同时降低碳排放;针对零售商的"搭便车"现象,通过分担部分制造商减排成本即可实现闭环供应链协调。最后,结合数值分析验证了以上结论。

Considering the different receptivity of new and remanufactured products,a game model was developed between a manufacturer and a retailer,and the impact of carbon tax on the production and pricing decisions of closed-loop supply chain were studied.Besides,the impacts of the manufacturer’s emission reduction investment on production decision and carbon emission were considered.The results show that the manufacturer can choose four different production strategies based on carbon intensity of the remanufactured products.Remanufacturing can deliver both economic and environmental benefits,but cannot offset the impact of carbon tax on the firm’s profits.The manufacturer’s investment in emission reduction can mitigate the impact of carbon tax and remanufacturing on new products to a certain extent,and reduce carbon emission while increasing supply chain revenue.For the"free rider"of the retailer,the closed-loop supply chain coordination can be realized by sharing the cost of emission reduction.Finally,the above-mentioned conclusions are verified by numerical analysis.
