技术创新、知识产权保护与企业新质生产力
Technological Innovation, Intellectual Property Protection and New Quality Productivity of Enterprises

文章基于2007~2022年我国新能源汽车上市企业的非平衡面板数据，构建双向固定效应模型，实证检验技术创新对企业新质生产力的线性和非线性影响，并研究知识产权保护在其中的作用机制。研究发现，技术创新对企业新质生产力的发展具有显著的正向线性促进作用。门槛效应检验表明，技术创新对企业新质生产力的影响存在单一门槛效应，即技术创新的边际贡献呈现先递增后递减的非线性变化趋势。中介效应检验显示，技术创新通过提升知识产权保护水平显著促进了企业新质生产力的提升。异质性检验结果表明，在东部地区和规模较大的企业中，技术创新对企业新质生产力的赋能作用更显著。基于此，本文提出不同技术创新阶段的策略、完善知识产权保护制度、构建知识产权保护与创新驱动相结合的路径，以及实施差异化策略以培育企业新质生产力的政策建议。
Based on the non-equilibrium panel data of China’s new energy vehicle listed enterprises from 2007 to 2022, this paper constructs a two-way fixed effect model, empirically tests the linear and nonlinear impact of technological innovation on the new quality productivity of enterprises, and studies the mechanism of intellectual property protection in it. It is found that technological innovation has a significant positive linear promotion effect on the development of new quality productivity of enterprises. The threshold effect test shows that there is a single threshold effect on the impact of technological innovation on the new quality productivity of enterprises, that is, the marginal contribution of technological innovation shows a nonlinear trend of increasing first and then decreasing. The intermediary effect test shows that technological innovation significantly promotes the improvement of new quality productivity of enterprises by improving the level of intellectual property protection. The results of heterogeneity test show that in the eastern region and large-scale enterprises, the enabling effect of technological innovation on the new quality productivity of enterprises is more significant. Based on this, this paper puts forward strategies for different stages of technological innovation, improving the intellectual property protection system, constructing a path for combining intellectual property protection and innovation-driven, and implementing differentiated strategies to cultivate new quality productivity of enterprises.
