摘要
本文基于中国277个地级市面板数据,采用动态系统GMM方法及面板门限模型实证检验了“金融发展—技术创新—产业升级”三者之间的关系。结果表明:金融规模和金融深化程度对技术创新具有显著促进作用,金融效率抑制了技术创新;金融发展和技术创新都能有效推动产业升级;技术创新在金融支持产业升级中发挥了重要的中介效应;门限效应结果表明,在不同的金融发展水平影响下,技术创新与产业升级间存在非线性影响效应,当金融发展达到某一水平时,技术创新能显著促进产业升级。可见,构建完善的金融体系对提高城市技术创新水平及促进城市产业升级具有重要意义。
Based on the panel data of 277 prefecture-level cities in China, this paper empirically tests the relationship among “financial development-technological innovation-industrial upgrading” by using dynamic system GMM method and panel threshold model. The results show that :(1) financial scale and financial deepening significantly promote technological innovation, and financial efficiency inhibits technological innovation;(2) both financial development and technological innovation can effectively promote industrial upgrading;Technological innovation plays an important role in financial support of industrial upgrading.(3) threshold effect results show that under the influence of different levels of financial development, there is a non-linear effect between technological innovation level and industrial upgrading. When the level of financial development reaches a certain level, technological innovation level can significantly improve industrial upgrading. It can be seen that the construction of a perfect financial system is of great significance to promote the level of urban technological innovation and urban industrial upgrading.
