出口专业化、空间依赖与我国地区经济增长

基于我国222个地级以上城市2001-2008年期间的样本数据,本文实证检验了出口结构与地区人均GDP增长率之间的关系。结果显示,出口集中度与地区经济增长之间存在显著正相关性,出口结构的专业化程度越高,地区人均GDP增长率相应越高。无论是采用经典OLS方法,还是采用控制空间依赖性的空间计量分析方法,这一结果均成立,其背后机制在于专业化导致生产活动的集聚,通过集聚经济提高生产率,从而促进人均产出的提高。本文政策含义在于,在当前发展阶段下,促进地区产业的集群化、专业化发展,充分发挥集聚经济,这对于扩大出口规模、推动地区经济增长具有积极意义。

Export Specialization,Spatial Dependence and Regional Economic Growth

This paper makes an empirical study on the relationship between export specialization and regional economic growth through employing data cover-ing 222 prefectural cities.The result reveals a positive relationship,that is,more specialized export structure is beneficial to regional growth.The result is robust to analysis employing both OLS and spatial econometric method.The relevant policy implication is to foster industrial agglomeration to fully exploit scale econo-my,which will in turn promote both export...
