摘　　要：选取285个地级及以上城市2007-2014年(不含2010年)数据为研究样本,以设立国家高新区的城市为处理组,未设立国家高新区的城市为对照组,将双重差分方法和空间计量模型结合起来,评估国家高新区及其科技创新对区域产业集聚的空间影响。实证结果表明,我国区域产业集聚存在明显的空间依赖性,国家高新区的设立具有显著正向的空间溢出效应,其科技创新对产业集聚的直接效应和间接效应均比较显著,这种影响在东部和中部地区更为明显。We selected the data of 285 cities at the prefecture level and above from 2007 to 2014(excluding 2010)as the research sample.Meanwhile,we set the cities having national high-tech zones(NHZs)as the treatment group and the cities without NHZs as the control group.Based on this,we used the difference-in-differences method and the spatial econometric model to evaluate the spatial effect of NHZs and their scientific-technological innovation on regional industrial agglomeration.Empirical results showed that,regional industrial agglomeration in China was spatially dependent,and NHZs had a significant positive spatial spillover effect.Furthermore,both the direct and indirect effect of NHZs scientific-technological innovation on industrial agglomeration were significant,which was more evident in the eastern and central regions.
