Abstract: This paper considers a dual-channel closed-loop supply chain consisting of one manufacturer and one e-commerce platform, in which the platform acts as the manufacturer’s recycling channel or introduces a secondary market through refurbishing the used product. The firm’s optimal pricing and recycling decisions under different contract forms (wholesale-price contract versus revenue-sharing contract) are analyzed in both cases in which the platform does not introduce or introduces the secondary market by applying the game-theoretical approach. It is found that when the substitution degree between different sales channels is high, the manufacturer may prefer the revenue-sharing contract if the commission rate charged by the platform is higher, but may prefer the wholesale-price contract if it is lower. The introduction of a secondary market by e-commerce platforms will incentivize manufacturers to increase their recycling prices of the used product, while potentially leading to either an increase or decrease in the volume of recycled product. Additionally, while the introduction of a secondary market may reduce the manufacturer’s profit, its impact on the profit of e-commerce platform remains context-dependent (either positive or negative). Investigating the firms’ optimal decision-making in a dual-channel closed-loop supply chain and the impact of the e-commerce platform’s introduction of secondary market provides a valuable complement to existing research on closed-loop supply chain and secondary market.
