考虑消费者对新能源汽车的续航能力需求和企业的创新能力,建立包含产业链上下游企业的技术创新决策模型,研究了分散决策和一体化决策两种决策方式,分析续航能力需求和企业的创新能力对电池供应商和汽车生产企业研发决策的影响,并设计了可以使产业链协同创新的机制,为产业链协同创新提供参考。结果表明：企业的创新能力和消费者的续航能力需求交互影响新能源汽车的续航能力；一体化决策可以实现产业链收益最大化,更能促进新能源汽车续航里程的提升和产业链的发展；创新成本分摊机制和创新补贴机制满足一定的条件就可以实现产业链一体化决策。

Considering the consumer"s demand for new energy vehicles" endurance capacity and the corporate innovation capabilities, a technology innovation decision model for upstream and downstream companies in the industrial chain is established to analyze two methods of decentralized decision-making and integrated decision-making. And we analyze the impact of innovation capabilities and consumer demand on the decisions of battery suppliers and new energy automobile manufacturers. We also design two mechanisms that can make the industry chain collaborative innovation to provide reference for collaborative innovation in the industrial chain. The results show that the innovation ability of the enterprise and the market demand of the consumers interact with each other to affect the level of endurance; the integrated decision-making can maximize the benefits of the industrial chain and promote the mileage of new energy vehicles and the development of the industrial chain; the innovation cost allocation mechanism and innovation subsidy mechanism can fulfill the industrial chain integration decision by satisfying certain conditions.
