摘　　要：城市边缘区是城市化进程中最具弹性的空间,兼有增量发展的战略纵深和存量发展的资源储备。然而,外延扩张与内涵优化范式的同时失灵导致城市边缘区发展停滞,并进入用地效率螺旋式衰减陷阱,成为制约城市化高质量转型的重要问题。首先,归纳了城市边缘区土地利用“效率陷阱”的三阶段模式,并揭示了低效土地利用的负反馈循环机制。在此基础上,从成本-收益视角构建了城市边缘区土地效率困境的多维度解释框架。其中,过度供地、区位劣势和技术洼地导致城市边缘区用地规模收益递减,而土地债务、社会治理和生态耗损构成城市边缘区用地成为边际成本递增的主要原因。最后,从经济、空间和社会3个维度提出“降本增收”的城市边缘区土地利用转型路径。The urban fringe(UF)is the most resilient space in the urbanization process,offering both the strategic depth for expansion and the resource reserves for stock development.However,the simultaneous failure of both the expansion and intensification paradigms has resulted in stagnant development within the UF,leading to a downward spiral of land use efficiency and posing a significant challenge to achieving high-quality urbanization.Firstly,this research summarizes a three-stage model of the“efficiency trap”in the land use within the UF and reveals the negative feedback circle mechanism of inefficient land use.Furthermore,a multidimensional explanatory framework is developed from a cost-benefit perspective to understand the dilemma of land use efficiency in the UF.Excessive land supply,disadvantageous location,and lagging technological development contribute to diminishing returns on land use scale within the UF.Meanwhile,land debt,social governance,and ecological degradation are key factors driving an increase in the marginal costs of land use within the UF.Finally,this research proposes a transformation path for land use within the UF that focuses on cost reduction and revenue increase,considering economic,spatial,and social dimensions.
