我国正经历着大规模的快速城镇化过程，区域管治和城镇土地集约利用是这一过程的重要主题。本研究以城镇土地的集约利用为研究对象，以“区域管治-空间外溢效应-影响机理-优化路径”为主线，在充分考虑城镇用地空间异质性的基础上，从复杂度、集聚度和效益度三个角度界定城镇用地集约度的内涵及表征。结合长江中游城市群的区域特征，从行政、交通、生态三个方面剖析区域管治的手段，测度和分析不同县市之间基于行政区划、交通流引力和生态补偿的多策略空间外溢模式，探索这三个方面的空间外溢效应对城镇土地集约利用的影响机理，并以此作为调控依据，进而提出基于区域管治的城镇土地集约利用优化路径，为推进新型城镇化发展和国土空间的开发和利用提供科学支撑。

China is experiencing rapid urbanization when regional governance and intensive urban land use are two important themes in this process. Regarding the intensive urban land use, we take “regional governance – spatial spillover effect – driving mechanism – optimization path” as the workflow. We comprehend and measure urban land use intensity in terms of complexity, aggregation degree and effectiveness degree on account of spatial heterogeneity of urban land. Considering the regional characteristics of urban agglomeration in the middle reach of Yangtze River, we approach the regional governance from the perspectives of administrative hierarchy, transportation and ecology, measure and analyze spatial spillover effect embedded in multiple scenarios of administrative restructuring, transportation flow and ecological compensation, and explore its effects on intensive urban land use. Based on the exploration on the driving mechanism in terms of spatial interaction, we propose the optimization path on intensive urban land use and provide reference for the promotion of New Urbanization and land development and utilization.
