摘要: 都市圈是区域城镇化的一种高级形态，而新城建设是大都市核心的扩散式重组，与都市圈功能重构和空间优化相伴而生。沿海地区及海湾都市圈具有开放的产业经济结构、高效的资源配置能力、强大的极化扩散功能和发达的国际合作网络，是经济发展和创新策源的核心区；适宜孕育多极的城镇网络体系，新城建设对都市圈格局优化的作用独特而显著。长三角核心区都市圈和环渤海湾都市圈是我国最重要的沿海及海湾都市圈，其中的上海与天津则是依托沿海及海湾都市圈生长发展的核心城市，但二者的圈域空间结构与新城建设模式又大相径庭。通过分析环渤海湾都市圈和长三角核心区都市圈，天津和上海市域城镇网络特征及新城建设的布局和时序，研究都市圈空间结构优化机制和发展要素流动机制，探索沿海及海湾都市圈“发展格局—空间格局”优化视角下新城建设与发展的模式。
Abstract: The metropolitan area is an advanced form of regional urbanization, and the construction of new towns is the diffuse reorganization of the core of the metropolis, which is accompanied by the functional reconstruction and spatial optimization of the metropolitan area. The coastal area and the gulf metropolitan area have open industrial economic structure, efficient resource allocation ability, strong polarization and diffusion function, and developed international cooperation network, and are the core areas of economic development and innovation strategies. It is suitable to breed a multipolar urban network system, and the new town construction plays a unique and significant role in optimizing the pattern of the metropolitan area. The Yangtze River Delta core metropolitan area and the Bohai Bay Rim metropolitan area are the most important coastal and gulf metropolitan areas in China. Shanghai and Tianjin are the core cities that rely on the coastal and gulf metropolitan areas for growth and development, but their regional spatial structure and new city construction mode are quite different. By analyzing the core metropolitan area of the Yangtze River Delta and the metropolitan area around the Bohai Bay, as well as the urban network characteristics of Shanghai and Tianjin and the layout and timing of new town construction, this paper studies the spatial structure optimization mechanism and development factor flow mechanism of the metropolitan area, and explores the mode of new town construction and development from the perspective of "development pattern and spatial pattern" optimization of coastal and gulf metropolitan areas.
