Abstract: To study temporal-spatial evolution of Anhui's urban construction land  use efficiency from perspective of China's high-quality development, this paper establishes an evaluation system which uses Anhui's 2006 to 2020 data and three-phased DEA model to incorporate industrial structural coordination, technical advance coordination and inner-external development coordination into environmental factor, quantitatively analyzes Anhui's urban construction land  use efficiency, temporally and spatially, and studies the projection analysis of inputs/outputs of urban construction land in non-DEA cities. From time scale, Anhui's urban construction land use efficiency has been high during 2006 to 2020, but the upward trend has slowed, with its Malmquist total factor productivity averaging at 1.023, mainly driven by technical advances. Spatially, Anhui's urban construction land use efficiency is high in northwest-southeast city zone (Huaibei-Huainan-Hefei-Tongling) and southwest-northeast zone (Lu'an-Chuzhou), a rough crossing pattern, which will be diffusing externally, taking Huaibei and Huainan cities as the cores in the northern Anhui, and Wuhu and Hefei in the southern Anhui. Redundance analysis indicates that Anhui's urban construction land use efficiency is chiefly impacted by urban industries & green coordinated development. On inputs, the redundant number of employees in urban secondary and tertiary industries is the major factor in constraining Auhui's urban construction land use efficiency. On outputs, irrational industrial structures, insufficient ecological production and inappropriate resource allocation are the key factors.

摘要: 为了研究安徽省城市建设用地利用效率在我国高质量发展视角下的时空演变情况,本文通过构建城市建设用地利用效率评价体系,并选取2006—2020年安徽省相关指标数据,运用三阶段DEA模型,把产业结构协调、技术进步协调、内外发展协调均纳入进环境因素,借此从时空2个维度对安徽省城市建设用地利用效率进行定量分析,并对安徽省非DEA有效设区市的城市建设用地投入及其产出指标进行投影分析。研究结果表明:1)从时间维度上看,2006—2020年安徽省的城市建设用地利用效率均处于较高水平,但上升趋势逐渐减缓,该省Malmquist全要素生产率变化指数的均值为1.023,技术进步是提升安徽省城市建设用地利用效率的主要驱动力量。2)从空间维度上看,安徽省城市建设用地高水平利用效率的空间分布主要沿着西北—东南城市带(淮北-淮南-合肥-铜陵)与西南-东北城市带(六安-滁州)大致成十字状对称布局,并且随着时间的推移,安徽省城市建设用地高水平利用效率还会沿着西北—东南、西南-东北2条轴线呈十字状向外扩散,其中在皖北地区主要以淮北、淮南2座资源型城市为核心向周边扩张,在皖南与江淮地区主要以芜湖、合肥2座交通枢纽城市为核心向周边扩张。3)通过冗余分析发现,安徽省城市建设用地利用效率主要受到城市产业协调发展和绿色协调发展的影响。在投入方面,城市第二、第三产业从业人数冗余是制约着安徽省城市建设用地利用效率提升的主要因素;在产出方面,安徽省各设区市的产业结构不合理、生态产出不足,以及资源配置不当等问题也均是制约着安徽省城市建设用地利用效率提升的重要因素。
