摘　　要：本文利用40家主要新能源汽车企业2015~2019年的面板数据,采用多元线性回归模型研究了政策补贴、研发投入与新能源企业创新绩效之间的互相影响。研究结果表明,政策补贴对企业研发投入有正向影响,且随着产业链从上、中、下游效果不断增加。对于创新绩效来说,上游企业研发投入的效果随时间不断减弱,企业融资的效果随时间加强。中、下游企业的研发投入效果随时间加强,政策补贴效果变化不大,在政策补贴逐年下降阶段,研发投入的增加有利于提高企业的创新绩效。更具针对性的补贴政策,可以推动资源的合理配置,有利于新能源汽车产业的良性发展。This paper uses panel data of 40 major new energy automobile enterprises from 2015 to 2019,a multiple linear regression model is used to study the interaction among policy subsidies,R&D investment and innovation performance of new energy enterprises.The results show that the policy subsidy has a positive effect on the R&D investment,and the effect increases with the industry chain from the upper,middle to lower reaches.For innovation performance,the effect of upstream enterprise R&D invest⁃ment is weakening with time,and the effect of enterprise financing is strengthening with time.The effect of R&D input of middle and downstream enterprises is strengthened with time,and the effect of policy subsidy is little changed.The increase of R&D in⁃vestment is beneficial to improving the innovation performance of enterprises.More targeted subsidy policy,can promote the rational allocation of resources,is conducive to the healthy development of new energy automobile industry.
