Theory building and technical innovations for spatial planning of China's metropolitan areas: insights from planning of Greater Shanghai Metropolitan Area

Abstract Based on limited theoretical applicability of metropolitan area concept under China’s circumstances and the planning practice in Greater Shanghai Metropolitan Area, this article proposes a Chinese understanding on the concept of “Metropolitan Area”, which extends its core connotation from a commuting area to a multi-functional area. It further proposes to utilize the preparation of spatial plans as means to promote high-quality development of metropolitan areas and to achieve coordinated regional development. Metropolitan area planning takes spatial planning as its basic attribute, and simultaneously embodies the contents of economic and social arrangements. It could become a binding contract based on consensus among member cities. In terms of technical innovations in planning practice, this article firstly suggests using a “problem-based, goal-targeted, action-driven, space-oriented and implementation-guided” approach to form a framework of “objective (indicator)-strategy-action-mechanism” to realize collaborative goals. Secondly, the spatial plan should focus on “bottom line factors” as well as “collaborative factors”, establishing a technical framework for regional spatial organization from multiple dimensions such as ecological pattern, city function, spatial structure, and conduction mechanism which drive transformations in regional governance modes.
