摘要
本文基于 2015-2020 年新能源汽车上市企业面板数据,运用DEA软件对创新效率进行测度,分析政府补助对新能源汽车企业创新效率的影响.结果表明:新能源汽车企业创新效率仍有提升空间,且创新效率主要受到规模效率的限制,政府补助可显著促进新能源汽车企业提高创新效率,二者之间存在"倒U型"关系.基于研究结论提出了相关政策建议,为政府优化补助政策提供参考.
Abstract
Based on the panel data of new energy vehicle listed companies from 2015 to 2020,this paper uses DEA soft-ware to measure innovation efficiency,and analyzes the impact of government subsidies on innovation efficiency of new energy vehicle companies.The results show that there is still room for improvement in the innovation efficiency of new energy vehicle companies,and innovation efficiency is mainly limited by scale efficiency.Government subsidies can significantly promote the innovation efficiency of new energy vehicle companies,and there is an"inverted U-shaped"relationship between the two.Based on the research conclusions,this paper puts forward relevant policy suggestions and provides a reference for the government to optimize subsidy policies.
