摘　　要：文章根据中国2000-2008年20个制造行业的面板数据,建立了以产业空间集聚水平为门限变量的双门限回归模型,以考察产业空间集聚对全要素生产率的影响机理。研究发现,产业空间集聚主要促进体现型技术进步,对技术效率的影响较弱;产业空间集聚的影响存在门限效应,其影响力随集聚水平的提高而逐步减弱,集聚规模存在最佳边界;产业空间集聚对全要素生产率及技术进步的影响在不同门限区间的行业技术梯度特征较明显,资源性和中低技术行业的集聚水平较低但集聚效应较高。Based on the panel data of 20 manufacturing industries in china from 2000 to 2008,this paper develops a double-threshold regression model with EG index as the threshold variable,in order to investigate the effects and mechanism of spatial concentration on TFP.The result suggests,industrial spatial concentration mainly promote embodied technical change,but the influence on technical efficiency is not strong enough;the effect of industrial spatial concentration has threshold effects,which is weakening with the raising degree of spatial concentration,and there is the most appropriate scale of spatial concentration;there exists a relationship between industry technique rank and spatial concentration＇s threshold effects,that is to say the spatial concentration of resource industries and low-tech industries is at a lower level,but promotes TFP growth and technical change more significantly.
