This paper established an evaluation index system for the land use efficiency from social, economic, ecological and environmental aspects, and adopted the variation coefficient TOPSIS method and obstacle degree model to analyze the regional differences of land use efficiency and obstacle degree in Xianning, Yueyang and Jiujiang. The results showed that: (1) During 2000-2010, the land use efficiency in these regions had an increasing tendency and the regional differences were small. In Yueyang and Jiujiang, there were four stages, that is low, moderate, good and excellent; while in Xianning, there were only three stages, that is low, moderate and good; (2) The economic level was the greatest obstacle factor affecting the land use efficiency in these regions, followed by the environmental quality, ecological status, social development, and the regional differences in these aspects were not so obvious; (3) Per area financial revenue, the output of comprehensive utilization of “three wastes” and per capita GDP were the top three obstacle factors and the regional differences in these aspects were not so obvious.
