目的 优化协调快递包装回收闭环供应链参与者的利益，促使提高废旧包装物回收率。方法 运用博弈论方法，构建由快递包装生产商、快递公司、互联网回收平台和消费者组成的闭环供应链模型，计算和比较在分散决策和集中决策时的利润，引入收益共享契约进行协调。结果 集中决策显著优于分散决策;协调后参与者的利润比协调前的有所提高，利润提高的幅度取决于协调比例大小，数值算例验证了该结果。结论 收益共享契约协调机制能够提高供应链系统利润，激发参与者积极回收快递包装，减轻对环境的污染，实现企业、消费者和社会共赢。建议政府积极推广“互联网+”的混合回收。

The work aims to optimize and coordinate the interests of participants in the closed-loop supply chain of express packaging recycling and promote the improvement of the recycling rate of packaging wastes. Based on the method of game theory, a closed-loop supply chain model composed of express packaging manufacturers, express companies, Internet recycling platforms and consumers was constructed, the profits in decentralized decision-making and centralized decision-making were calculated and compared, and the revenue sharing contract for coordination was introduced. The results showed that centralized decision-making was significantly better than decentralized decision-making. The profit of participants after coordination was higher than that before coordination, and the range of profit increase depended on the coordination proportion. A numerical example verified the results. The following conclusion is made that the revenue-sharing contract coordination mechanism can improve the profits of the supply chain system, stimulate participants to actively recycle express packaging, reduce environmental pollution, and achieve a win-win situation for enterprises, consumers and society. The government is recommended to actively promote "Internet+" mixed recycling.
