碳税政策下平台供应链置换策略研究
Research on Platform Supply Chain Substitution Strategies under Carbon Tax Policy

在政府补贴和碳税政策的背景下，本文探讨了消费者置换策略的影响，并建立了平台与再制造商之间的Stackelberg博弈模型。本研究关注两类消费者：新型消费者和替代型消费者，其中新型消费者直接购买新产品或再制造产品，替代型消费者参与以旧换新或以旧换再计划；分析了转售模式和直售模式两种不同的置换渠道以及模式的内部对比、不同模式的对比。研究结果表明，政府的碳税政策在一定程度上对产品定价和需求产生了积极影响。当补贴较低时，替代型消费者的需求在两种模式下均高于新型消费者的需求，补贴较高时则相反。而较高的碳税率使得转售模式下的再制造商利润优于直售模式下的利润。
In the context of government subsidies and carbon tax policies, this paper explores the impact of consumer replacement strategies and establishes a Stackelberg game model between platforms and remanufacturers. The study focuses on two types of consumers: new consumers and alternative consumers, where new consumers directly purchase new or remanufactured products, and alternative consumers participate in trade-in or exchange programs. It analyzes two different replacement channels: the resale model and the direct sales model, as well as the internal comparison of these models and comparisons between different models. The research results indicate that the government’s carbon tax policy has a positive impact on product pricing and demand to some extent. When subsidies are low, the demand from alternative consumers is higher than that of new consumers in both models, while the opposite is true when subsidies are high. Additionally, a higher carbon tax rate leads to greater profits for remanufacturers in the resale model compared to the direct sales model.
