Abstract: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.
