Efficiency evaluation on urban land use system and diagnosis of its obstacle indicators would be greatly helpful for sustainable land use. On the basis of evaluation on the comprehensive efficiency of urban land use in Changzhou city, this paper used a theoretical model to assess the land use efficiency. The evaluation index system was built with the indices of economic efficiency, social efficiency, and ecological efficiency. As urban land use is a complex multi-objective system, the evaluation index system was constructed based on the gray correlation TOPSIS method. Results showed that: (1) the urban land use efficiency was gradually increasing, with the efficiency index increasing from 0.347 4 to 0.641 3 during the period 2001—2011, the degree of land use efficiency generally experienced two stages, i.e., medium performance, and good performance; (2) in the long run, the economic efficiency was found to be the major factor affecting urban land use efficiency, the obstacle degree of economic efficiency increased by an annual average of 7.67%, but the obstacle degree of economic and ecological efficiency decreased by an annual average of 2.34% and 6.96%, respectively; (3) GDP of per investment in fixed assets, Engel coefficient of urban households were verified to be the key obstacle for further improvement of urban land use efficiency. Finally, we put forward the main pathway to improve urban land use efficiency according to the status of urban land use.
