EVALUATION OF URBAN CONSTRUCTION LAND USE EFFICIENCY AND OPTIMIZATION STRATEGY OF LAND ALLOCATION:BASED ON THE EMPIRICAL STUDY ON 2,165 MUNICIPAL DISTRICTS,COUNTY-LEVEL CITIES,AND COUNTIES IN CHINA
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.
