运用DEA模型,分析内蒙古自治区101个旗县区城镇用地效率,揭示土地利用空间分异特征,寻求城镇用地空间格局的优化路径。研究结果表明:(1)内蒙古自治区城镇用地效率平均值为0.510,用地效率整体水平不高,投入产出要素存在一定程度的投入冗余或产出不足。(2)从空间上看,东中西三个空间格局的用地效率空间差异显著,个别地区因产业不同而表现出较大的特殊性。(3)从规模上看,城镇用地效率与经济发展水平有一定的线性关系,城镇用地规模梯度在分布上呈现出“金字塔”型,在不同经济规模下,用地效率规模差异明显。因此,提升内蒙古城镇用地效率、优化空间结构,需要根据各地区资源禀赋和经济发展,因地制宜地进行优化配置。
Using DEA model, the paper analyzes the land use efficiency of 101 counties in Inner Mongolia Autonomous Region, reveals the characteristics of spatial differentiation of land use, and seeks for the optimal path of urban land use. The results show that: (1) The average urban land use efficiency in Inner Mongolia Autonomous Region is 0.510, the overall land use efficiency is not high, input-output factors have some input redundancy or insufficient output. (2) From the perspective of space, the space efficiency of the three spatial patterns of East, West and East has significant differences in space efficiency, and some regions show great peculiarities due to different industries. (3) From the perspective of scale, the efficiency of urban land use and the level of economic development have a certain linear relationship. The scale of urban land use scale shows a “pyramid” distribution. Under different economic scales, the scale of land use efficiency is obviously different. Therefore, to enhance the urban land use efficiency and optimize the spatial structure in Inner Mongolia, we need to optimize the allocation according to local conditions according to the resource endowments and economic development in each region.
