The panel data of 50 new energy vehicle enterprises in Shanghai and Shenzhen A-shares from 2012 to 2021 are selected to empirically analyze the impact of government subsidies on the innovation of new energy vehicle enterprises and to further discuss the differences between such an impact in different forms and regions. The study finds that, first, government subsidies have a certain promotion effect on the innovation of new energy vehicle enterprises, and an inverted U-shaped relationship exists thereof. Second, at the enterprise level, government subsidies have a significant effect on the innovation of non-state enterprises, downstream vehicle enterprises, and enterprises with lower establishment years, and the inverted-U trend is evident. Third, at the regional level, government subsidies have a more significant effect on the innovation of enterprises in non-eastern regions and low-environmental regulation regions, and the inverted-U-shaped relationship trend is more apparent. The study establishes the nonlinear relationship between government subsidies and the innovation of new energy vehicle enterprises through empirical research, which expands the theory of enterprise innovation and has a certain guiding significance for improving the innovation capability of new energy vehicle enterprises in the future.
选取了 2012 年至 2021 年上海和深圳 A 股的 50 家新能源汽车企业的面板数据,实证分析了政府补贴对新能源汽车企业创新的影响,并进一步探讨了不同形式和地区的影响差异。研究发现,首先,政府补贴对新能源汽车企业的创新有一定的促进作用,且存在倒 U 型关系。其次,在企业层面,政府补贴对非国有企业、下游汽车企业和成立年限较低的企业的创新有显著影响,且倒 U 趋势明显。第三,在区域层面,政府补贴对非东部地区和低环境监管地区企业的创新影响更为显著,倒 U 型关系趋势更为明显。本研究通过实证研究建立了政府补贴与新能源汽车企业创新之间的非线性关系,拓展了企业创新理论,对未来提高新能源汽车企业创新能力具有一定的指导意义。
