摘要: 研究新型城镇化对城市土地绿色利用效率的影响,对实现城镇化高质量发展和城市土地可持续利用具有重要意义。以2005~2020年长三角地区41个城市为研究样本,采用超效率SBM模型、窗口分析法、空间面板杜宾模型等方法,探析了新型城镇化对城市土地绿色利用效率的影响及空间效应。结果表明:(1)研究期内,新型城镇化水平呈波动上升趋势,城市土地绿色利用效率呈波动变化趋势。分区域来看,二者均呈现为上海>浙江>江苏>安徽的特征。新型城镇化水平与城市土地绿色利用效率空间差异明显。 (2)新型城镇化水平与城市土地绿色利用效率存在明显的空间正相关关系。双变量全局Moran’s I的变化趋势呈现明显的“M”型,二者总体空间依赖特征明显。 2010年以后,新型城镇化与城市土地绿色利用效率局部空间关联类型增加,高高集聚区主要分布在苏南地区和浙北地区,低低集聚区主要分布在苏北地区和皖北地区。(3)新型城镇化能够显著提升城市土地绿色利用效率,且具有正向空间溢出效应。人口密度、对外贸易水平、科技水平、产业结构高级化和政府规模对其产生不同程度的影响。 

Abstract: Studying the impact of new-type urbanization on urban land green use efficiency is of great significance for achieving high-quality development of urbanization and sustainable use of urban land. Using 41 cities in the Yangtze River Delta region from 2005 to 2020, the impact of new-type urbanization on urban land green use efficiency and spatial effect were analyzed using methods of super efficiency SBM model, window analysis method, and spatial panel Durbin model. The results showed that: (1) the level of new-type urbanization showed a fluctuating trend, and urban land green use efficiency showed a fluctuating trend. From a regional perspective, the characteristics in the order of Shanghai > Zhejiang > Jiangsu > Anhui were presented. The spatial difference between new-type urbanization and urban land green use efficiency was obvious. (2) There was a significant spatial positive correlation between the level of new-type urbanization and urban land green use efficiency. The change trend of bivariate global Moran's I presented an obvious “M” type, and the overall spatial dependence of the two was obvious. The local spatial correlation types between new-type urbanization and urban land green use efficiency had been increasing, after 2010, with high concentration areas mainly distributed in southern Jiangsu and northern Zhejiang, and low concentration areas in northern Jiangsu and northern Anhui. (3) New-type urbanization can significantly improve urban land green use efficiency, showing a positive spatial spillover effect. Population density, foreign trade level, science and technology level, industrial structure and government scale all have different degrees of impacts.
