The circular economy seeks to reduce waste by reusing, refurbishing, and recycling used products. It increases the resource value of used goods. In this study, we proposed a circular business gap exploiter model in which a re-commerce company exploits residual value in product systems utilization. A game-theoretic approach is used to investigate the coordination problem of a two-echelon circular supply chain with e-commerce and re-commerce companies. In addition, we proposed a coordinated structure under the revenue sharing contract and the two-part tariff contract through Nash negotiation to address the coordination problems. We compared the centralized and decentralized model findings and observed that the decentralized model shows potential for improvement. We showed model's applicability through numerical examples and sensitivity analysis to indicate how parameters such as wholesale price and retail price affect channel decisions and member profits. The results show that a two-part tariff contract may efficiently coordinate the circular supply chain. The study shows that under a circular business model, two tactics may be applied. These are extending product value and extending resource value.

分析电子商务行业循环供应链的协调策略：一种博弈论方法

循环经济寻求通过再利用、翻新和回收用过的产品来减少浪费。它增加了旧货的资源价值。在这项研究中，我们提出了一个循环业务差距开发者模型，在该模型中，一家电子商务公司利用产品系统利用中的剩余价值。博弈论方法用于研究二级循环供应链与电子商务和再商务公司的协调问题。此外，我们通过纳什协商提出了收入共享契约和两部分关税契约下的协调结构，以解决协调问题。我们比较了集中式和分散式模型的发现，发现分散式模型显示出改进的潜力。我们展示了模型' 通过数值示例和敏感性分析的适用性来说明批发价和零售价等参数如何影响渠道决策和会员利润。结果表明，两部分关税合同可以有效地协调循环供应链。该研究表明，在循环商业模式下，可以应用两种策略。这些是延伸产品价值和延伸资源价值。
