Spatial-temporal Differences and Convergence of Urban Land Use Efficiency in Changjiang River Economic Belt

CHEN En;DONG Jie;XU Lei;College of Public Administration,Huazhong Agricultural University;  
The model of super SBM was used in this paper to analyze the spatial differences of urban land use efficiency in Changjiang River Economic Belt by using the input-output data,then the dynamic evolution was analyzed in total factor productivity(TFP)of urban land by using Malmquist index,and examined the convergence of urban land in various groups of cities.The results showed that:The overall level of urban land use efficiency in Changjiang River Economic Belt was relatively low,and its spatial distribution showed significant regional differences.The urban land use efficiency had a typical effect of increasing scale.The larger urban scale was,the higher land use efficiency.The TFP of urban land use tended to decline,but the influencing factors were different.The results of convergence test showed that TFP of urban land use in the same sizes converged and eventually converged to the respective steady-state levels,and among all cities of different sizes were not disappear automatically at short time.
