【摘要】 采用三阶段DEA及Tobit模型分析中国大陆省际城市用地扩张效率及其影响因素,为提升城市用地扩张效率提供政策依据。研究结果表明:①剔除环境变量和统计干扰后,综合效率均值为0.79,纯技术效率均值为0.89,规模效率均值为0.89。②环境变量对投入要素的冗余变量影响显著,经济水平、政府扶持和区位因素对要素投入冗余有抑制作用;对外开放对非农劳动力和土地要素投入冗余存在正向影响,产业结构对非农劳动力冗余存在正向影响。③经济水平对城市用地扩张效率存在显著正向影响,产业结构与平均高程对城市用地扩张效率存在显著负向影响。研究结论:为提升城市用地扩张效率,应结合地区自然条件实施差别化管控政策,优化要素在区域间的合理配置。更多还原

【Abstract】 Using three-stage DEA and Tobit model to analyze interprovincial urban land use expansion efficiency and influencing factors in mainland China, this paper has provided policy basis for improving the efficiency of urban land expansion. The results show that after removing environmental variables and statistical interference, the mean value of comprehensive efficiency, pure technical efficiency, and scale efficiency is 0.79, 0.89, and 0.89 respectively. Furthermore, environmental variables have significant influence on redundant variables of input factors; while the economic level, government support and location factors have an inhibitory effect on the redundancy of factor input. Opening to the outside world has a positive impact on non-agricultural labor and land input redundancy;and industrial structure has a positive impact on non-agricultural labor redundancy. In addition, economic level has a significant positive impact on the efficiency of urban land expansion; while industrial structure and average elevation have significant negative effects on the efficiency of urban land use expansion. On this basis, this paper points out that In order to improve the efficiency of urban land expansion, differentiated control policies should be implemented in accordance with local natural conditions, and optimizing the reasonable allocation of elements between regions.更多还原
