城市建设用地利用效率评价及驱动因素分析

Evaluation of Urban Construction Land Use Efficiency and Its Driving Forces in China

综合考虑城市建设用地经济效益、社会效益和环境效益的基础上,运用DEA模型测度2011-2015年中国31个省份城市建设用地利用效率,分析各个省份城市建设用地利用在时间和空间上的差异,随后用面板回归模型探究影响城市建设用地利用效率的因素。研究表明:(1)2011-2015年全国城市建设用地综合效率呈小幅度波动上升趋势,东部地区城市建设用地利用效率最高,中部地区城市建设用地利用效率呈逐年上升趋势且变化幅度较大,西部地区效率有明显下降趋势;(2)我国城市建设用地利用的空间格局相对稳定且相邻省份城市建设用地利用呈现集聚现象;(3)经济发展水平、产业结构以及土地财政与城市建设用地利用效率存在非线性关系。最后,根据研究结论,对如何提高城市建设用地利用效率提出了切实可行的政策建议。

Based on the comprehensive consideration of the economic,social and environmental benefits of urban construction land use,this paper uses the DEA model to measure the urban land use efficiency of the 31 provinces in China from 2011 to 2015,and analyzes the spatial and temporal distribution of land use in each province.Then use the panel regression model to explore the factors that affect the efficiency of urban construction land use.The results show that:(1)The comprehensive efficiency of urban construction land use in China shows an increasing trend with little change from 2011 to 2015.The urban construction land use efficiency is the highest in the eastern region.The land use efficiency in the central region shows a rapid upward trend,and the land use efficiency in the western region has a clear downward trend;(2)The spatial pattern of urban construction land in our country is relatively stable and the urban construction land between adjacent provinces shows agglomeration;(3)There is a nonlinear relationship between the level of economic development,industrial structure,land finance and urban construction land use efficiency.Finally,based on the conclusion of the study,this paper puts forward feasible policy suggestions.
