【摘要】：以城市为空间单位,利用DEA-Tobit模型考察了城市土地利用效率特征以及城市通达性、产业结构对其的影响。主要研究结论是:(1)中国城市土地利用综合效率表现呈现"中心-外围"式递减特征,城市土地利用效率规模效益随城市化率呈"S"型曲线特征;(2)土地供应结构是土地利用效率提升的关键制约因素;(3)城市土地利用效率随着距省会城市距离增加呈现倒"U"型变化;(4)产业结构越高级城市土地利用效率越高;(5)城市通达性的改善对于不同产业结构对城市土地利用效率的影响具有调节效应;(6)城市通达性、产业结构对于城市土地利用效率影响随地理区位变动呈现双门槛效应。最后,本文从优化土地供应结构、促进城市产业升级、立足区位禀赋完善交通基础设施等方面提出中国城市土地利用效率提高的相关政策建议。
[Abstract]:Taking the city as the spatial unit, the effects of urban land use efficiency, urban accessibility and industrial structure on urban land use efficiency were investigated by using DEA-Tobit model. The main conclusions are as follows: (1) the comprehensive efficiency of urban land use in China is characterized by "central-peripheral" decline. The scale benefit of urban land use efficiency shows "S" curve characteristic with urbanization rate; (2) the structure of land supply is the key restricting factor of improving land use efficiency; (3) urban land use efficiency is inverted with the increase of distance from provincial capital city. "U" type change; (4) the higher the industrial structure, the higher the urban land use efficiency; (5) the improvement of the urban accessibility has the adjustment effect on the different industrial structure to the urban land use efficiency; (6) the urban accessibility, The effects of industrial structure on urban land use efficiency show double threshold effect with geographical location change. Finally, this paper puts forward some policy suggestions on how to improve the efficiency of urban land use in China from the aspects of optimizing the structure of land supply, promoting the upgrading of urban industry, and perfecting the transportation infrastructure based on location endowment.
