In order to solve the problem of inefficient land use in Guangxi and improve the intensive degree of land use conservation in Guangxi, combined with the construction land and agricultural land in the overall structure of land resources use, the index system of evaluation of construction land and agricultural land use efficiency was constructed from the point of view of society, economy, land, capital, labor force and environment, respectively. The land use efficiency of 14 prefecture-level cities in Guangxi was comprehensively calculated and evaluated by DEA-Malmquist index in this paper, and the temporal and spatial variation pattern of total factor productivity was analyzed. The comprehensive analysis showed that the efficiency of agricultural land use in Guangxi was generally in the trend of growth, and the construction land in Guangxi was in the trend of growth. The overall utilization efficiency was in the decreasing trend, and the failure to pay attention to the improvement of utilization efficiency and the improper management of construction land planning and management were the key factors of low land use efficiency in Guangxi. Finally, combined with the analysis results, some suggestions for the future urban development of Guangxi were put forward.
