The remanufacturing green closed-loop supply chain plays a crucial role under current global environmental pressures, especially in the high-tech manufacturing industry. This study addresses a two-level remanufacturing green closed-loop supply chain system composed of remanufacturers and retailers. Considering incentive compatibility theory under uncertain demand, we establish supply chain optimization models under different decision-making scenarios and analyze supply chain optimization issues through game theory in centralized, decentralized, contract decentralized, and differential subsidy modes. The study finds that: (1) Companies can guide the establishment of green supply chains through secondary subsidies; (2) TE and AE models each have advantages under different carbon emission sensitivity conditions; (3) The AE model is overall superior to other models; (4) Government intervention can effectively enhance profits and reduce carbon emissions. This paper is the first to apply incentive compatibility theory to an uncertain two-level remanufacturing green supply chain, helping enterprises build green supply chains, and proposes a dual regulatory strategy of carbon taxes and subsidies. This provides theoretical support and practical guidance for the formulation of differentiated incentive policies by governments and the green transformation of enterprises, aiding high-tech manufacturing companies in constructing remanufacturing green supply chains and enhancing their market competitiveness.
