我国分省区城市化效率的实证研究

An Empirical Study on the Urbanization Efficiency of Provinces in China

利用我国31省区2002-2006年间的数据,运用DEA和Malmquist指数分析方法,从动态角度考察我国各省区的城市化效率,并测算了各省区城市化过程中投入要素的集约效率。结果表明,我国大部分省区的城市化效率不断降低,这主要是由技术变动的无效导致的;其次,各省区的投入要素非集约化度很高,其城市化过程仍旧主要依靠投入要素的粗放型扩张。随着资源约束的增强,各省区应该坚持走依靠科技进步的、集约化、节约型的城市化发展之路。

Based on DEA and Malmquist Index, this paper analyzes the urbanization efficiency for 31 provinces from the dynamic perspective, using the data from 2002 to 2006. And also, this paper calculates the intensive efficiency of the input factors in the urbanization process. The results show that the urbanization efficiency is decreasing for most provinces, mainly caused by the ineffective technology change. Because of the low intensive efficiency of input factors, the urbanization process for most provinces is extensive, mainly depending on the huge inputs. The restriction of resources is becoming stronger and stronger, so every province should insist on the intensive and economical urbanization way, which mainly depends on the technical progress.
