摘要:: [目的]探究东北三省城市土地利用效率时空差异及影响因素,为东北三省和其他欠发达地区的城市高质量发展和优化国土空间格局提供借鉴参考。[方法]运用超效率SBM模型、非参数核密度估计以及Tobit回归模型对2010—2020年东北三省城市土地利用效率时空差异及影响因素进行分析。[结果](1)从时间演变特征来看,东北三省城市土地利用效率均值呈显著上升趋势,但整体水平不高; 从空间演变特征来看,区域差异显著,低值区城市数量大幅度减少,高值区城市增多,高值区城市分布范围从黑龙江覆盖至东北三省全域。(2)从时序动态演进特征来看,研究期间不同时段内三大省份城市土地利用效率的极化程度、效率差异和发展水平都呈现出不同的动态演进特征。(3)从影响因素分析来看,各变量对辽宁、吉林、黑龙江三省城市土地利用效率的影响程度和作用方向有所差异,人力资本、科教支出、经济发展水平、对外开放程度、产业结构、交通基础设施和城镇化率具有促进作用,环境规制具有抑制作用。[结论]实现城市高质量发展和土地集约高效利用,各城市应因地制宜、因城施策,从刺激经济增长、产业结构优化升级、优化营商环境、做好人才和资金引进工作等方面系统推进。

Abstract:: [Objective] Exploring the spatial and temporal differences in urban land use efficiency and the influencing factors in the three northeastern provinces can provide reference for high-quality urban development and optimization of territorial spatial pattern in the three northeastern provinces and other less developed regions. [Methods] Spatial and temporal differences in urban land use efficiency and the influencing factors in three northeastern provinces from 2010 to 2020 were analyzed by using super-efficient SBM model, non-parametric kernel density estimation and Tobit regression model. [Results](1)In terms of temporal evolution characteristics, the average value of urban land use efficiency in the three northeastern provinces showed a significant upward trend, but the overall level was not high. In terms of spatial evolution characteristics, there were significant regional differences, the number of cities in the low value area decreased significantly, the number of cities in the high value area increased, and the distribution range of cities in the high value area covered the whole area of the three northeastern provinces from Heilongjiang.(2)In terms of the dynamic evolution characteristics of time series, the polarization degree, efficiency difference and development level of urban land use efficiency in the three provinces showed different dynamic evolution characteristics in different time periods during the study period.(3)From the analysis of influencing factors, the degree and direction of influence of each variable on urban land use efficiency in Liaoning, Jilin and Heilongjiang provinces differed, with human capital, expenditure on science and education, level of economic development, degree of openness to the outside world, industrial structure, transportation infrastructure and urbanization rate having a facilitating effect and environmental regulation having an inhibiting effect. [Conclusion] To achieve high-quality urban development and intensive and efficient use of land, each city should systematically promote from stimulating economic growth, optimizing and upgrading industrial structure, optimizing the business environment, and doing a good job of introducing talents and capital according to local conditions and city-specific policies.
