技术创新影响产业结构的空间传导路径分析

Analysis of spatial conduction path of technological innovation affecting industrial structure

摘要:

在理论分析技术创新影响产业结构优化升级路径的基础上，构建技术创新评价指标，引入三种不同类型空间权重，选取2000-2015年我国30个省级面板数据进行空间杜宾模型实证检验，结果表明：技术创新不仅促进了本地产业结构，还有助于邻近地区合理化发展，但对邻近地区高级化的抑制作用和促进作用并存；省域间技术创新和产业结构具有显著空间相关性，产业结构高级化存在正向溢出效应而产业结构合理化却有着负向溢出效应；技术创新能够通过一条直接路径和空间效应形成的三条间接路径作用于本地及其他地区产业结构；技术创新对产业结构的作用方向和强度存在较大区域差异。据此，加强技术创新提升产业结构结构的“先富带后富”，是可以通过政策引导实现的。

Abstract:

On the basis of the theoretical analysis of technological innovation affecting the industrial structure optimization and upgrading, constructing technical innovation evaluation indicators ,introducing three different types of spatial weights,and selecting 30 provincial panel data in China from 2000 to 2015 for space Dubin Model empirical test.The results show that technological innovation not only promotes the local industrial structure, but also contributes to the rationalization of neighboring areas.However, it has both inhibitory effect and promotion effect on advancement in neighboring areas.The inter-provincial technological innovation and industrial structure have significant spatial correlation,and the industrial structure advancement has a positive spillover effect while the industrial structure rationalization has a negative spillover effect.Technological innovation can act on local and other regional industrial structures through a direct path and three indirect paths formed by spatial spillover effects. There are large regional differences in the direction and intensity of technological innovation on industrial structure.Accordingly, the effect of "first enrichment, second enrichment" of enhancing industrial structure through technological innovation can be realized through policy guidance.
