中文摘要:
      [目的]研究中国2000-2015年282个地级以上城市的土地利用效率演化特征,为中国资源优化布局和土地利用效率持续提升提供参考。[方法]采用VRS-DEA模型和GIS空间分析方法,研究282个地级以上城市土地利用效率的演化特征与影响因素。[结果]①中国城市的土地利用效率处于中低水平。其中,东部城市效率最高,西部城市居次,中部城市最低;城市规模越大,效率越高,增速越快。②土地利用效率由纯技术效率和规模效率共同作用,但纯技术效率贡献力大于规模效率。东部城市和高等级城市更具有纯技术效率的优势。③土地利用效率的影响因素从建成区面积、第三产业从业人员数的投入过量,发展到固定资产投资额、第二产业从业人员数的投入过量。同时,第二产业增加值产出不足的影响显著大于第三产业。[结论]应针对不同区域、不同规模等级的城市采用差异化的路径来提升土地利用效率,如严格控制超大、特大城市的规模;有针对性的控制大城市规模;加大中等城市和小城市的纯技术要素投入。
英文摘要:
      [Objective] This paper studies the evolution of land use efficiency of 282 prefecture-level cities in China from 2000 to 2015 in order to provide a reference for the optimization of resource allocation and the continuous improvement of land use efficiency.[Methods] The VRS-DEA model and GIS spatial analysis method were used to study the evolution characteristics and its influential factors of land use efficiency in 282 prefecture-level cities.[Results] ① The land use efficiency of Chinese cities was at a low level. Among them, the eastern city had the highest efficiency, the western city took the second place, and the central city had the lowest efficiency. The larger of the city, the higher of the efficiency and the faster of the growth rate was. ② The land use efficiency was caused by pure technical and scale efficiency, pure technical efficiency contributed more than the scale efficiency. Eastern cities and high-grade cities had more advantages of pure technical efficiency. ③ Influencing factors of land use efficiency were changed from the built area and the excessive investment of the number of employees in the tertiary industry into the investment in fixed assets and the excessive investment of the number of employees in the secondary industry. At the same time, the impact of the insufficient output value-added of the secondary industry was significantly greater than that of the tertiary industry.[Conclusion] Different solutions need to be used to improve the land use efficiency in different regions and cities at different scales, for example, strictly control the scale of megacities and mega cities, control the scale of large cities in a targeted manner, and increase the investment of pure technical efficiency in medium-sized cities and small cities.
