Abstract: Improving construction land use efficiency is an effective approach to conflicts of human and land, and is of significance in land sustainable development. This paper uses CCR model in DEA to estimate the construction land use efficiency in Xinjiang's 88 cites (counties), with the result generally showing a low efficiency, namely more-input-less-output. 56.82% of the cities (counties) are less than the average and DEA effective units concentrate in the northern Xinjiang. The spatial differentiation is also distinct, highest in the north, lowest in the east, and middle in the south. This paper presents suggestions on reducing proportional land input production elements, optimizing industrial structure, improving labors abilities and using advanced technologies in increasing construction land use efficiency.

摘要： 提高建设用地利用效率是解决人地矛盾的有效途径之一，对于实现土地资源的可持续利用具有重要意义。采用DEA中面向投入的CCR模型对新疆88个县市进行建设用地利用效率测算，研究表明：新疆建设用地利用效率整体较低，投入多且产出不足，5682%的县市低于全疆平均水平，DEA有效单元多集中于北疆地区；建设用地利用效率空间分异特征显著，呈现出北高南低的特征，建设用地利用效率值在北疆最高，南疆其次，东疆最低。造成这一现象的主要原因是建设用地面积和资金投入过多，投入比例不协调，建议采用减少一定比例的土地投入生产要素、优化升级产业结构、提升劳动力综合水平以及采用先进的科学技术方法等手段提高建设用地利用效率。
