摘要
为弥补用地效率研究缺乏全域评估、存在概念混淆、难以指导实务等不足,本文以中国31个省、自治区、直辖市的2 165个市辖区、县级市、县为分析单元,采用SBM-undesirable模型计算各区市县城市建设用地利用效率,量化用地效率与供应的匹配程度和匹配类型,以为指标分配提供依据.中国城市建设用地效率整体偏低,保守估计,近七成区市县拥有冗余用地;若要达到最优效率,全国可削减冗余城市建设用地2.45万km2.人口规模、行政等级与用地效率呈U型关系,人均GDP对用地效率具有边际递减的正向影响.中国城市面临用地利用效率与用地供应速率的空间错配问题,应根据两者匹配关系分类施策,对"效率不足-供应过剩型"和"效率较高-供应不足型"区市县的计划及周转指标分别给予压缩和调增,以实现总量稳定、效率提升、刚弹结合、动态调整的用地指标分配优化目标.
Abstract
To make up for the lack of nationwide evaluation,confusion of concept,and difficulties in guiding practice in the studies of land use efficiency,this paper takes 2,165 municipal districts,county-level cities,and counties in China as analysis units and uses SBM-undesirable model to calculate urban construction land use efficiency.In order to provide the basis for optimized allocation of land use quota,the paper measures the matching degree and matching type between land use efficiency and land supply rate.According to conservative estimates,the overall urban construction land use efficiency in China is relatively low.Nearly 70％of municipal districts,county-cities,and counties have redundant urban construction land.To reach the optimal efficiency,24,500 square kilometers redundant land should be cut down nationwide.There is a U-shaped relationship between population size,administrative grade,and land use efficiency.Per capita GDP shows a marginally-decreasing positive impact on land use efficiency.As some Chinese cities are faced with spatial mismatch between land use efficiency and land supply rate,targeted measures should be taken according to the matching relationship between land use efficiency and land supply.For example,land quota should be reduced for the"inefficient but oversupplied"cities and increased for the"efficient but undersupplied"cities to stabilize the total quota,so as to improve land use efficiency,combine rigidity and elasticity of regulation,and realize dynamic adjustment.
