在闭环供应链视角下，为提高新能源汽车动力电池回收率，构建了新能源汽车制造商与零售商之间实施成本分摊契约和责任分摊契约两种不同的双渠道电池回收博弈模型，并以单渠道回收模式为参考，研究不同回收契约下双渠道回收模式对新能源汽车零售价格、市场需求、电池回收率及供应链成员利润的影响。通过理论研究发现：一定条件下，两种不同的回收契约双渠道回收模式总能降低新能源汽车市场价格、扩大市场需求以及增加电池回收率和供应链成员利润。当新能源汽车制造商回收成本系数较大时，新能源汽车制造商更偏好采用回收成本分摊契约，而当制造商回收成本系数较小时，新能源汽车制造商更偏好采用回收责任分摊契约。当零售商回收成本系数较大时，零售商更偏好采用回收责任分摊契约，而当零售商回收成本系数较小时，零售商更偏好采用回收成本分摊契约。

From the perspective of the closed-loop supply chain, in order to increase the recovery rate of the power battery of new energy vehicle, two different dual-channel battery recycling game models have been constructed between the new energy vehicle manufacturer and the retailer to implement the cost sharing contract and the responsibility sharing contract. The single-channel recycling model is used as a reference to study the impact of the dual-channel recycling model under different recycling contracts on the retail price of new energy vehicles, market demand, battery recycling rate and supply chain member profits. Through theoretical research, it is found that under certain conditions, two different recycling contracts dual-channel recycling modes can always reduce the market price of new energy vehicle, expand market demand, and increase battery recycling rate and supply chain member profits. When the new energy vehicle manufacturer's recovery cost coefficient is large, the new energy vehicle manufacturer prefers to adopt the recovery cost sharing contract, and when the manufacturer's recovery cost coefficient is small, the new energy vehicle manufacturer prefers to use the recovery responsibility sharing contract. When the retailer's recovery cost coefficient is large, the retailer prefers to adopt the recovery responsibility sharing contract, and when the retailer's recovery cost coefficient is small, the retailer prefers to use the recovery cost sharing contract.
