江苏省建设用地利用效率和全要素生产率的时空差异分析

Analysis on Spatial and Temporal Difference of Construction Land Use Effi ciency and Total Factor Productivity in Jiangsu Province

研究目的:以江苏省为例,对比分析江苏省62个县(市、区)1999—2011年来建设用地利用效率和全要素生产率的时空差异。研究方法:数据包络分析方法和Malmquist指数方法。研究结果:(1)江苏省建设用地利用效率区域差异较大,1999—2011年全省建设用地利用效率先降后升,最低点出现在2008年左右;(2)江苏省大部分地区存在全要素生产率增长,2008年以前主要依靠技术进步,2008年以后主要依靠综合效率的提升。研究结论:江苏省正处于投资驱动向创新驱动转变阶段,应根据各市县社会经济发展特征和不同级别,制定差别化的建设用地利用方案,合理配置生产要素,提高技术进步率,为全国实现"要素驱动"、"投资驱动"转向"创新驱动"提供一定的参考。

The purpose of the study is to analyze the spatial and temporal difference of economic efficiency and total factor productivity of the construction land use in Jiangsu Province from 1999 to 2011. Method employed is the Data Envelopment Analysis（DEA）. The results show that 1） the economic efficiency of construction land in Jiangsu Province is generally low, and the efficiency of central and northern Jiangsu below average of whole province. The economic efficiency of construction land decreased first and then increased from 1999 to 2011, and the lowest point occurred in 2008. 2） The Malmquist indexes of many regions in Jiangsu Province are increasing from 1999 to 2011. The main reason is technological progress before 2008, however the main reason is efficiency improvement after 2008. We suggest that in light of the need of economic and social development and different administrative levels, properly distribute production factors, hasten technical progress, and formulate plans for the differential construction land. The finds may also serve as the reference of the shift from “factor driven” and “investment driven” to the so-called “innovation driven”.
