中国城市全要素土地效率及其影响因素分析

摘要

The article,by using land stock,capital stock and labor employment as input and city GDP as output,employs super-efficiency DEA to estimate the total factor land efficiency of cities above prefecture-level in China and analyzes its in⁃fluencing factors as well. The results show that Chinese urban total factor land efficiency is generally low,industrial structure and the rapid expansion of urban construction land restrict the improvement of land efficiency,human capital and the role of government are beneficial to the improvement of land efficiency,the reform of land marketization promotes the improvement of land efficiency,but not significant. The above factors have different impacts in different regions.%文章使用土地存量、资本存量、劳动力就业人数作为投入要素，以城市国内生产总值作为产出变量，使用超效率DEA方法测算中国地级以上城市全要素土地效率，并对中国城市全要素土地效率的影响因素进行分析。结果表明，中国城市全要素土地利用效率普遍不高，产业结构和城市建设用地的快速扩张限制了土地效率的提高，人力资本和政府的作用有利于土地效率的提高，土地市场化改革促进了土地利用效率的提高，但不显著。上述因素在不同地区的作用有所偏重。
