建设用地扩张对经济增长的贡献及其区域差异研究

研究目的：应用1999 — 2007年分省数据，测度近年建设用地扩张对中国及不同区域经济增长的贡献及变化趋势，为土地政策制定提供依据。研究方法：效率评价法、多元回归分析法、比较分析法。研究结果：（1）1999 — 2007年中国固定资本、劳动力和建设用地的产出弹性分别为0.745、0.274和0.083；（2）初级产品阶段地区、工业化阶段地区、发达经济阶段地区建设用地的产出弹性分别为0.376、0.068和0.066；（3）地区技术效率和土地宏观调控对建设用地扩张存在显著抑制作用。研究结论：（1）建设用地扩张对经济增长的贡献随着发展阶段演进逐渐减小；（2）对处于不同发展阶段的地区，应实行差别化的土地管理策略与绩效考核方法。

Study on Contribution of Construction Land Expansion to Economic Growth and Its Regional Difference

The purpose of this paper is to estimate the contribution of construction land expansion to economic growth in different regions in recent years based on data of different provinces from 1997-2007 in order to offer a reference for making proper land policies for China. Methods of technical efficiency analysis, comparative analysis and econometrics analysis were employed. The results indicate that:（1） the input-output elasticity of fixed capital, labor were construction land were 0.745, 0.274 and 0.083 respectively during 1999-2007;（2） the input-output elasticity of construction land were 0.376, 0.068 and 0.066 in three types of regions with different economic development stages, which are primary-good-processing stage, deeper industrializing stage and completely developed stage, respectively;（3） regional technical efficiency and macro land control have resulted in a significantly negative impacts on construction land expansion. It is concluded that:（1） the contribution of construction land expansion to economic growth has gradually attenuated with the economic development process from primary stage to advanced stage;（2） areas at different development stages should use differentiated strategies of land administration and criterion for officials’ performance assessment.
