Abstract: Considering whether the e-commerce platform alone bears the recycling service cost or shares the cost of recycling service cost with the remanufacturer, and taking into account whether the e-commerce platform chooses a loan strategy to lift the capital constraint or not, game models of e-commerce closed-loop supply chain under platform’s capital constraint are constructed. The corresponding optimal strategies are solved and analyzed, and the conditions for the remanufacturer to share the service costs and for the E-commerce platform to choose a loan strategy are given. The results show thatwhen the e-commerce platform has capital constraint, though the remanufacturer shares part of recycling service costs, alsosplits profit of the e-commerce platform, which can achieve a win-win situation for both parties. When the e-commerce platform does not choose a loan strategy, the more self-owned funds, the more beneficial the remanufacturer will be. But when the e-commerce platform chooses a loan strategy, the more self-owned funds, the more favorable to the e-commerce platform but the remanufacturer is no longer influenced. Moreover, as self-owned funds increases,the proportion of service costs shared by the remanufacturer will be reduced, and the degree of recycling service improvement will be reduced. It is the best choice for the e-commerce platform to induce the remanufacturer to share the recycling service costs and choose a loan strategy together to lift the capital constraint.
