The Internal Mechanism of the Influence of Government Subsidy on Enterprise Innovation Performance:Research on New Energy Enterprises

以2013—2017年我国新能源行业265家企业为样本,运用泊松回归和负二项回归估计方法研究政府补助促进新能源上市公司创新绩效影响的内在机制,结果表明:政府直接补助和税费返还均对新能源上市公司创新绩效有显著的正向影响;高管团队创新意识在政府补助与研发投入之间存在部分中介效应,研发投入在高管团队创新意识与创新绩效之间存在部分中介效用;同时政府补助对处于不同生命周期的新能源上市公司创新绩效的调节作用有显著差异。

Taking 265 enterprises in the new energy industry of China from 2013 to 2017 as samples,using Poisson regression and negative binomial regression,this paper studies the internal mechanism of government subsidies promoting innovation performance of new energy listed companies.The results are as follows:Firstly,both direct government subsidy and tax rebates can significantly promote innovation of executive team innovation consciousness of new energy listed companies.Secondly,executive team innovation consciousness has some intermediary effect between government subsidy and R&D investment,and R&D investment has some intermediary effect between executive team innovation consciousness and innovation performance.At the same time,there are significant differences in the regulation effect of government subsidy on innovation performance of new energy listed companies in different life cycles.
