在现代城市空间规模不断扩大，逐步形成区域尺度的都市区和都市圈的过程中，交通的作用日益突出，尤以公共投资为主的大运量轨道交通为甚，由此引发各界对二者互动关系的关注和讨论。为研究促进交通建设与空间发展相互协调、进而支撑都市区和都市圈健康发展的机制和要素，本文选择巴黎都市区作为实证案例，基于文献资料、规划本文和实地观察，对巴黎都市区自工业化以来城市化进程的三个阶段进行历时性定性分析，总结巴黎都市区轨道交通建设与都市区空间发展的互动关系以及促进二者相互协调的机制和要素，以期对质量优先的新型城镇化背景下，我国都市区和都市圈的规划建设提供参考借鉴。文章发现，利用公共交通，特别是轨道交通引导城市建设是法国规划领域基于历史经验的自觉实践。以此为借鉴，广泛的社会认同、统一的政策框架、有效的规划协调和系统的管理治理是轨道交通建设支持都市区空间发展的重要机制和基础。

Urban transportation has always been closely interrelated with urban space. In the modern time, as urban development kept going, turning cities into metropoles and megalopolises, the role of transportation became more and more significant, in particular that of mass rail transit. In consequence, the interaction between transportation construction and spatial development called due concerns from the academia and the society. In order to find out the keys to promoting the coordination between the two aspects to support the sustainable development of metropoles and megalopolises, a case study on Paris Region is conducted based on literature, documents and observations. Dividing the evolution of Paris metropolitan area into three phases in line with the process of urbanization, the paper reviews the interaction between transportation construction and spatial development in a chronological way and summarizes the mechanisms and factors facilitating the coordination between them. It concludes that the empirical experience of Paris Region proves that broad social consensus, unified policy framework, effective planning coordination, and systematic management and governance are the key to promoting the coordination between transportation construction and spatial development, which can serve as useful reference for the planning and development of China’s metropolitan and megalopolitan areas in the era of New Urbanization.
