技术创新对高技术产业全球价值链升级的驱动作用——来自湖北省高技术产业的证据

The Driving Role of Technological Innovation in Promoting the High-tech Industry's Status in the GVC——the Evidence from High-tech Industry in Hubei Province

随着我国经济从高速增长阶段向高质量发展阶段转换,提升高技术产业在全球价值链的分工地位已成为迫切需要解决的问题。依据2002-2016年湖北省高技术产业数据,运用面板数据模型方法实证分析创新要素对高技术产业价值链地位的影响,揭示技术创新驱动高技术产业全球价值链升级机制,并运用结构方程模型检验创新驱动高技术产业全球价值链升级路径。研究发现:基础创新、产品创新和创新绩效对于提升高技术产业在全球价值链的分工地位具有重要作用。其中,产品创新的贡献最为显著,基础创新和创新绩效都有明显贡献,政府支持有待加强,企业家精神亟待培育;技术创新驱动高技术产业全球价值链升级的中介效应因创新要素而异,基础创新主要通过产业结构升级,创新绩效主要通过提高产业效率和增加产业效益,产品创新则通过产业效率提升、产业结构升级、产业效益增加来提升价值链地位。

With the transformation of China's economic growth model from high speed to high quality,the promoting of the hightech industry's status in the GVC has been increasingly concerned by the government and academia.Based on the data of high-tech industry in Hubei province from 2002 to 2016,this paper applies panel data model to empirically analyze the impact of innovation factors on the status in the GVC,then uses structural equation model to examine the path of technological innovation to promote the high-tech industry's status in the GVC.The results shows that basic innovation,product innovation and innovation performance play an important role in promoting the high-tech industry's status in the GVC,among this innovation factors,the contribution of product innovation is the most significant,basic innovation and innovation performance have a significant contribution,but government support is not enough,entrepreneurship needs to be nurturing;the intermediary effect of promoting the high-tech industry's status in the GVC by technological innovation varies with the innovation factors,basic innovation promotes the GVC through optimizing the industrial structure,innovation performance promotes the GVC through promoting industrial efficiency and increasing the industrial benefit,product innovation promotes the GVC through promoting industrial efficiency,optimizing the industrial structure and increasing the industrial benefit.
