Based on the connotation of green development, SBM-Undesirable model was used to measure the land use efficiency of Lanxi Urban Agglomeration in 2006, 2010, 2014 and 2018, and Theil Index and Spatial Autocorrelation Methods were used to reveal the spatial difference characteristics. The results show that: (1) From 2006 to 2018, the county land use efficiency of Lanxi Urban Agglomeration increased steadily, and the regional differences first expanded and then narrowed. (2) The land use efficiency of counties in Lanxi Urban Agglomeration presents a spatial difference law of “high in the middle-low in the periphery, high in the west and low in the east, and differentiated between the north and the south”, while the two provinces present a decreasing law of “west-east”. (3) The spatial agglomeration characteristics of land use efficiency in Lanxi Urban Agglomeration are remarkable. Locally, the high-high agglomeration is typical in the central region, while the low-low agglomeration spreads from southeast to southwest.
