This paper examines pricing and replenishment decisions for seasonal and nonseasonal products in a three-echelon shared supply chain. We adopt a time-varying demand function and propose two models (off-season and peak season) for seasonal products, three models for nonseasonal products based on the relative dominance of nonplatform members in the case of the complete information game, and a static Bayesian model in the case of the incomplete information game. For the seasonal products, we find that the chain members should adjust their optimal decisions based on the dominance shifts from the retailer to the factories and the change in the seasonal factor, but for nonseasonal products, the optimal decisions are related only to the channel powers of nonplatform members and not to seasons. In addition, an interesting finding is that the sharing platform's subsidy to the retailer is ineffective under the complete information game, while the subsidy enables the retailer to reduce the retail price and increase the order quantity under the incomplete information game. We also reveal the impacts of some key parameters on the shared chain members.

本文研究了三级共享供应链中季节性和非季节性产品的定价和补货决策。我们采用随时间变化的需求函数，针对季节性产品提出两种模型（淡季和旺季），基于非平台成员的相对优势，提出三种针对非季节性产品的模型，以及静态贝叶斯模型信息博弈不完整的情况下的模型。对于季节性产品，我们发现连锁店成员应根据从零售商到工厂的主导权转移以及季节性因素的变化来调整其最佳决策，但对于非季节性产品，最佳决策仅与渠道权力相关非平台成员，而不是季节。此外，一个有趣的发现是，共享平台对零售商的补贴在完整的信息博弈下是无效的，而补贴使零售商在不完整的信息博弈下降低零售价并增加了订购数量。我们还揭示了一些关键参数对共享链成员的影响。
