How to deal with the relationship between land intensive use and ecological environment, and realize the coordinated development of economic, social and ecological benefits of land use is an important issue in the construction of new urbanization. This paper used the panel data of 30 provinces, municipalities and autonomous regions in China from 2005 to 2015 to measure the comprehensive index of land intensive use and ecological efficiency through the global principal component analysis method and the super-SBM model, in an attempt to reveal the coordinated development of land intensive use and ecological efficiency. The results showed that: (1)The level of land intensive use showed a gradual increasing trend, and the growth rate rendered as east > west > middle. (2) The ecological efficiency increased year by year, and the growth rate rendered as east > middle > west; (3) In 2015, 30 % of provinces had reached coordinated development, 40% of provinces were on the verge of disorder, and 30% of provinces were in disorder. Among them, Shanghai, Hainan and Xinjiang were lagging in ecological efficiency, while other provinces were lagging in land intensive use. In addition, the coupling coordination degree had a weak spatial negative correlation. Most of the eastern coastal areas were H-L type, the central and western regions were mostly L-H type, and the three northeastern provinces were L-L type.
