摘 要:[目的]在高质量发展视角下探讨城市土地绿色利用效率的内涵,定量分析江苏省城市土地绿色利用效率的时空变化与影响因素,为江苏省提升城市土地绿色利用效率提供科学参考。[方法]利用Super-SBM-Undesirable模型、GIS空间分析和面板数据模型,系统研究了2008—2020年江苏省城市土地绿色利用效率的区域差异和变化特征。从“分权化、绿色化、全球化”三方面,检验其对城市土地绿色利用效率的影响。[结果]①江苏省城市土地绿色利用效率处于较高水平,多数城市2018年前呈下降趋势,2018年之后出现上升趋势。空间上整体表现出“北低南高,西低东高”的格局。②江苏省各地区城市土地绿色利用效率波动差异明显,苏北与苏中为先增大后减小,苏南为先减小后增大。③森林覆盖率、公园绿地面积、外商直接投资和产业结构对城市土地绿色利用效率呈促进作用,城市发展水平对其为U形非线性影响。财政压力是导致城市土地绿色利用效率下降的主要原因。[结论]未来要倡导高质量发展模式,从加强区域一体化,促进地方产业结构转型升级,改变经济发展方式等方面分地区制定不同的优化调整措施,以提高江苏省城市土地绿色利用效率。[Objective]The spatiotemporal differentiation and influencing factors of urban land green use efficiency in Jiangsu Province were quantitatively analyzed based on an exploration of the connotation of urban land green use efficiency from the perspective of high-quality development in order to provide a scientific reference for increasing urban land green use efficiency.[Methods]The Super-SBM-Undesirable model,GIS spatial analysis,and panel data model were applied to investigate the regional disparity and evolution characteristics of urban land green use efficiency in Jiangsu Province from 2008 to 2020.The impact on the green use efficiency of urban land was examined from the three aspects of“decentralization,greening,and globalization”.[Results]①The green use efficiency of urban land in Jiangsu Province was at a relatively high level.Most cities showed a downward trend before 2018 and an upturn after 2018.The overall spatial distribution could be characterized as“low in the north and high in the south,low in the west and high in the east”.②The fluctuation difference of urban land green use efficiency was obvious in Jiangsu Province.Urban land green use efficiency in northern and central Jiangsu Province increased first and then decreased,while in southern Jiangsu urban land green use efficiency decreased first and then increased.③Forest coverage rate,park green space area,foreign direct investment,and industrial structure promoted green use efficiency of urban land,while the level of urban development produced a U-shaped nonlinear effect on green use efficiency.Financial pressure was the main contributor to the decrease in green use efficiency of urban land.[Conclusion]In the future,it will be necessary to advocate for the creation of high-quality development models and formulate different optimization and adjustment measures in different regions based on strengthening regional integration,promoting the transformation and upgrading of local industrial structure,and changing the mode of economic devel
