都市圈一体化研究进展与展望

一体化发展是区域高质量发展和协调治理的新要求，由于其空间尺度不同，出现了区域一体化、城市群一体化和都市圈一体化等多个概念。都市圈是城市群的重要组成单元和城镇化的重要空间载体，加强都市圈一体化研究，对于实现区域内部、区域与国家、区域与全球的协调融合发展具有重要意义。本文对近20年来中国都市圈一体化相关研究文献进行梳理。综述结果表明：(1)一体化及都市圈概念尚未形成统一的定义，使得都市圈一体化在概念表述上存在一定差异。(2)研究理论框架多借鉴经济学和管理学，理论的适配性限制了对都市圈一体化的机理研究。(3)多学科交叉融合研究匮乏，高适配性的理论体系构建还有待加强。(4)随着国家发展战略调整和区域一体化实践的深入，都市圈一体化研究正面临制度、功能、生态、文化和关系等方面的转向。

RESEARCH AND PROSPECT OF METROPOLITAN AREA INTEGRATION

Integration is a new requirement of regional high- quality development and coordinated governance. Due to it's different spatial scales, there are many concepts, such as regional integration, urban agglomeration as well as metropolitan area integration. Metropolitan area is an important spatial unit of regional high-quality development and urbanization. Strengthening the research on the integration of metropolitan area is of great significance to realize the coordinated and integrated development within the region, between the region and the country, among the region and the world. This paper reviews the related literature on the integration of metropolitan areas in China during the past 20 years. It shows that: 1) Neither integration nor the metropolitan area has a well-recognized concept definition, which ultimately creates different conceptual expressions of metropolitan area integration. 2) The theoretical framework of metropolitan area integration research is mostly derived from economics and management. The adaptability of the theory limits the research mechanism analysis of metropolitan area integration. 3)There is a lack of interdisciplinary and integrated research, and the research of highly adaptive theoretical system needs to be continuously strengthened. 4)With the adjustment of national development strategies and the deepening of regional integration practices, the research on metropolitan area integration is facing the transformation of institution, function, ecology, culture and relationship. However, the current research on the integration of metropolitan areas in China's academic circles is relatively weak, with a number of problems still exist, such as confusion of concepts, poor integration of disciplines, weak theoretical system, and not closely combined with the strategy of the times.
