Research on Cost-Sharing Contract for New Energy Vehicle Battery R&D Based on Quality and Price Sensitivity

Abstract

Aiming at the battery quality improvement bottleneck of new energy vehicles, this paper introduces the R&D cost-sharing contract under the dual-sensitivity demand to battery quality level and vehicle retailer price. We establish game models dominated by the vehicle manufacturer, and analyze the impact mechanism of the cost-sharing contract on decisions and profits of new energy vehicle supply chain players. We further discuss the coordination of the new energy vehicle supply chain. The result shows that the cost-sharing contract can improve the quality level of new energy vehicle batteries, and increase the vehicle manufacturer's profit under certain conditions. But a pure cost-sharing contract can not achieve supply chain coordination because the battery supplier is not interested in it. A combination of the cost-sharing contract and transfer payment contract can coordinate the supply chain.
