科技创新对产业结构升级的影响研究——以长江经济带为例

Research on the Impact of Science and Technology Innovation on the Upgrading of Industrial Structure——Taking the Yangtze River Economic Belt as an Example

文章运用长江经济带9省2市2007-2018年的数据构建动态系统GMM估计和静态面板相结合的模型,将长江经济带分上中下游进行区域分析,研究科技创新对产业结构升级的影响机制,研究结果显示:从总体上看,科技创新确实能够促进产业结构升级,但存在区域间的差异性,下游地区科技创新对产业结构的促进作用更加明显,上游地区略显乏力。各地区应加大对科技创新投入力度,以此促进产业结构升级,实现长江经济带经济高质量增长。

The article uses the data from 2007 to 2018 in 9 provinces and 2 cities in the Yangtze River Economic Belt to build a model that combines dynamic system GMM estimation and static panels.The results show that,overall,scientific and technological innovation can indeed promote the upgrading of industrial structure,but there are regional differences.The scientific and technological innovation in the downstream region has a more obvious role in promoting the industrial structure,and the upstream region is slightly weak.All regions should increase their investment in technological innovation to promote the upgrading of industrial structure and achieve high-quality economic growth in the Yangtze River Economic Belt.
