The purpose of this paper is to explore the cooperation issues in a consignment supply chain with complementary products under Online to Offline Business Mode (O2O mode). The centralized, decentralized and cooperative game-theoretic decision models are developed, analyzed and compared for a generic consignment supply chain with complementary products under O2O mode. Similar models are also developed for that under pure online- and offline-channel modes for comparison purpose. The corresponding numerical and sensitivity analyses are conducted to validate the analytical findings and derive managerial insights. It is found that the cooperative strategy always creates many more profits for the supply chain by setting a much lower retail price and generating much more demands than those of the decentralized strategies. The best supply chain strategy for a consignment supply chain with complementary products sold through both online and offline channels is identified as the cooperative strategy. An extensive sensitivity analysis of seven key parameters on an O2O cooperative decision model has derived several insightful findings for the O2O consignment supply chain practitioners with complementary products. These managerial insights will facilitate better decision-making for the O2O retailers and their complementary suppliers. Since the cooperation of a consignment supply chain under O2O mode with complementary products is a fresh research domain, there are more research issues to be explored.

本文的目的是探讨在线到离线业务模式下代销产品与补充产品的供应链中的合作问题。（O2O模式）。在O2O模式下，针对具有互补产品的通用托运供应链，开发，分析和比较集中，分散和合作的博弈决策模型。还针对纯在线和离线通道模式下的模型开发了类似模型以进行比较。进行了相应的数值和敏感性分析，以验证分析结果并得出管理见识。结果发现，与分散策略相比，合作策略通过设定更低的零售价格和产生更多的需求，总是为供应链创造更多的利润。通过在线和线下渠道出售互补产品的托运货供应链的最佳供应链策略被确定为合作策略。O2O合作决策模型上七个关键参数的广泛敏感性分析为具有互补产品的O2O寄售供应链从业人员得出了一些有见地的发现。这些管理洞察力将有助于O2O零售商及其互补供应商做出更好的决策。由于O2O模式下的寄售供应链与互补产品的合作是一个崭新的研究领域，因此有更多的研究问题需要探索。
