Research on the Spatial Effects of Digital Technology Innovation Driving the Transformation and Upgrading of the Manufacturing Industry

研究数字技术创新驱动制造业转型升级的作用机制对社会生产力飞速跃升有重要意义。文章建立空间计量模型实证检验数字技术创新影响制造业转型升级的空间效应。结果发现：(1) 全国制造业转型升级在空间上存在正向相关关系，以低高集聚和低低集聚模式为主；(2) 数字技术创新对制造业转型升级具有直接促进作用，对邻近地区表现出负向空间溢出效应，产业链现代化水平、劳动生产率和出口技术复杂度在创新驱动转型升级过程中起正向调节作用；(3) 产业结构和虚拟集聚达到一定的阈值，促进作用显著加强。Studying the mechanism by which digital technological innovation drives the transformation and upgrading of the manufacturing industry is of great significance for the rapid rise of social productivity. This paper establishes a spatial econometric model to empirically test the spatial effect of digital technological innovation on the transformation and upgrading of the manufacturing industry. The results show that: (1) There is a positive spatial correlation in the transformation and upgrading of the manufacturing industry across the country, mainly in the form of low-high and low-low agglomeration patterns; (2) Digital technological innovation has a direct promoting effect on the transformation and upgrading of the manufacturing industry, and shows a negative spatial spillover effect on neighboring regions. The modernization level of the industrial chain, labor productivity, and the complexity of export technology play a positive moderating role in the process of innovation-driven transformation and upgrading; (3) When the industrial structure and virtual agglomeration reach a certain threshold, the promoting effect is significantly strengthened.
