Enterprise S&T Innovation's Driving Effect on the Upgrading of Industrial Structure:A Study Based on the Empirical Analysis of Shandong Province

科技创新对于产业结构的升级优化有着重要意义.选择2003-2018年山东省地级市的面板数据,运用动态差分GMM估计方法分析山东省企业科技创新对产业结构升级的作用。分析结果显示,提高企业科技创新能力有助于山东省的产业结构升级;政府的科技支持力度对产业结构合理化存在一定的抑制作用,但会明显促进产业结构高度化水平。提升企业科技创新能力,完善政府财政科技支出的产业结构和地域结构,加强产学研的深度交流与融合,可以有效促进产业结构的进一步优化升级。

Scientific and technological innovation is of great significance for the upgrading and optimization of industrial structure.The panel data of prefecture-level cities in Shandong Province from 2003-2018 are selected to analyze the role of S&T innovation of enterprises in Shandong Province on the upgrading of industrial structure using dynamic differential GMM estimation method.Results of the analysis show that improving enterprise S&T innovation capacity helps to upgrade the industrial structure of Shandong Province;the government's S&T support has a certain inhibitory effect on the rationalization of industrial structure,but will significantly enhance the height of industrial structure.Improving enterprise S&T innovation capacity,improving the industrial and geographical structure of the government's S&T expenditure,and strengthening the in-depth communication and integration of industry,academia and research can effectively promote the further optimization and upgrading of the industrial structure.
