TEMPORAL-SPATIAL EVOLUTION OF URBAN CONSTRUCTION LAND USE EFFICIENCY IN ANHUI PROVINCE VIEWING FROM HIGH-QUALITY DEVELOPMENT
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.
