Aiming at the problems of land use and development gap in the process of economic development of cities of different sizes,this paper used Super-SBM model,spatial autocorrelation method and spatial convergence method to study the land use efficiency and convergence of these cities from 2008 to 2019.The results indicated that:(1)The land use efficiency of big cities and small cities showed an upward trend,while the Megalopolis and medium-sized cities saw a small decrease in this aspect.At the same time,the efficiency wouldn't be increased as the scale of the city was enlarged;(2)The spatial correlation results showed that the spatial agglomeration effect of land use efficiency was increasing in the study area;(3)The urban land use efficiency of cities varying in scale displayed obvious β convergence.Considering the spatial factors,government intervention,economic development and other control variables could accelerate the speed of convergence.As such,the results can be used as a reference for formulating differentiated land use regulation policies to narrow the economic development gap and achieve common prosperity.
