摘要
文章从城镇化角度研究产业集聚的技术溢出效应，选取1986-2011年中国省际数据，采用非参数DEA方法测算各省全要素生产率的增长，并运用面板门槛模型估计，检验不同城镇化条件下，集聚效应与全要素生产率增长的非线性关联。研究结果表明，产业集聚对全要素生产率增长的促进作用存在门槛效应，促进效果随着城镇化水平的提高而显著增强。在城镇化背景下，产业集聚对全要素生产率的作用渠道主要是促进技术进步，对于技术效率的影响不明显。
Based on China's provincial data from 1986 to 2011,this paper probes the technology spillover effect of industrial agglomeration from the angle of urbanization by verifying the nonlinear relationship between TFP and the industrial agglomeration at different levels of urbanization with the nonparametric DEA method and the panel threshold model.The empirical result shows that there is threshold value for the promotion effect of industrial agglomeration on TFP,and the effect is more and more obvious with the increasing improvement of urbanization level.Besides,this paper indicates that the industrial agglomeration promotes TFP growth mainly by promoting the technological progress rather than the technical efficiency.
