摘　　要：基于DEA-VRS模型、全局莫兰指数、G^(i)_(*)指数和灰色关联分析,探究2009—2020年皖江城市带9个城市建设用地利用效率的时空格局演变特征及其驱动因素.结果表明:时间维度上,皖江城市带建设用地利用效率整体呈上升趋势,其中综合效率呈“下降—上升”周期循环波动的变化特征,纯技术效率平均值整体呈先升后降的变化趋势,规模效率经历了“下降—上升—平稳—上升—下降”5个阶段的变化过程.空间维度上,皖江城市带建设用地利用效率空间关联性和地域不均衡性并存.2009、2020年建设用地利用效率呈现强烈的空间负相关和空间正相关,随年份演进,空间集聚程度进一步增强;呈现“中东部高、西部低”的分布格局.皖江城市带建设用地利用效率时空差异的演变受区位条件、产业结构、城镇化水平、人地关系、政府规制等多种因素综合驱动.因此,要发挥合肥、芜湖等城市的“排头兵”作用,推进以县域为重要载体的城镇化建设;实施区域协调发展战略,提升区域一体化的速度和程度.Based on the DEA-VRS model,Global Moran's I,G^(i)_(*)and GRA,the characteristics of the spatiotemporal pattern evolution and its driving factors of the construction land use efficiency in the Wanjiang city belt from 2009 to 2020 are explored.The results show that the overall trend of construction land use efficiency in the Wanjiang city belt is on the rise in the time dimension,among them,the comprehensive efficiency is characterized by cyclical fluctuations of"down-up",the average value of pure technical efficiency as a whole shows a trend of change first up and then down,and the scale efficiency has experienced a five-stage change process of"down-up-stable-up-down".The spatial correlation and geographical imbalance of construction land use efficiency in the Wanjiang city belt coexist in the spatial dimension.The construction land use efficiency showed strong negative and positive spatial correlation in 2009 and 2020 respectively,and the degree of spatial agglomeration was further enhanced with the evolution of years,displaying a spatial distribution pattern of"high in the central-eastern part and low in the western part".The evolution of spatiotemporal differences in construction land use efficiency in the Wanjiang city belt is driven comprehensively by multiple factors,such as location conditions,industrial structure,urbanization level,human-land relationship,and government regulation.Therefore,it is proposed to play the the role of the"front-runner"of Hefei,Wuhu and other cities,promote the construction of urbanization with the county as an important carrier;deepen the implementation of regional coordinated development strategy,enhance the speed and degree of regional integration.
