新能源汽车产业政府R&D补贴效果的实证研究

An Empirical Study on the Effects of Governmental R&D Subsidy upon New Energy Automobile Industry

采用2011—2015年中国新能源汽车产业上市公司面板数据,通过静态与动态面板数据模型分析了政府直接补贴、间接补贴对企业R&D投入的影响。研究结果表明:政府直接补贴对企业R&D投入的激励效应显著,而政府间接补贴对企业R&D投入的影响存在一定的不确定性;同时,企业规模、知识存量显著促进了政府R&D补贴的作用效果,而企业技术水平对政府R&D补贴的影响效果不明显。在上述结论基础上,为提高政府R&D补贴有效性,应完善以下政府职能:加强官方信息的披露,提高补贴政策的稳定性与针对性,充分发挥政府直接补贴、间接补贴的作用,建立完善的补贴准入和退出机制。

Based on the panel data of Chinese listed companies in the new energy automobile industryfrom 2011 to 2015, the effects of direct governmental subsidies and indirect subsidies on enterprises’ R＆D investment were investigated by using the static and dynamic panel data models. The results showed that direct governmental subsidy has a significant incentive effect on enterprises’ R＆D investment, while indirect subsidy has uncertain impacts on enterprises’ R＆D investment. At the same t im e ,firm size and knowledge stock contribute to governmental R＆D sub sidy, while the effect of enterprises’ technological level on governmental R＆-D subsidy is not remarkable.
