The Agglomeration of High-tech Industries and the Core Competitiveness of Manufacturing Industry——Evidence from Construction of National High-tech Zone
The high-quality development of the equipment manufacturing industry is a critical mani-festation of the core competitiveness of China's manufacturing industry.Taking the establishment of nation-al high-tech zones as a quasi-natural experiment,a staggered difference-in-differences model was used to empirically test whether high-tech industrial agglomeration promotes the core competitiveness of China's manufacturing industry.The research found that compared with cities without national high-tech zones,the agglomeration of high-tech industries brought by national high-tech zones significantly promoted the in-crease in the quantity and quality of technological innovation in the equipment manufacturing industry in the region.The construction of national high-tech zones shows an obvious effect in the eastern region,central region,and non-resource-based cities,on contrast,it cannot bring the same effect in the western re-gion,northeast region,and resource-based cities cannot bring the same effect.The mechanism test found that the national high-tech zones in the eastern and central regions have a positive impact on the technolog-ical innovation of the equipment manufacturing industry by gathering human capital and optimizing the in-dustrial structure,but the national high-tech zones in the western region and the northeastern region are difficult to form the effect of human capital agglomeration and the optimization effect of the industrial struc-ture,which results in the high-tech industry agglomeration can not be effectively empowered by the upgra-ding of the core competitiveness of the manufacturing industry.
