从单中心城市向日益多中心城市地区的转变在最近的研究文献中得到了广泛认可。尽管多中心一般是指同一区域内存在多个相邻中心，但许多研究强调城市体系中心之间的功能联系也是多中心的重要组成部分。尽管有关功能多中心性的研究越来越多，但该主题的研究仍处于发展阶段。本文提出了一种衡量功能多中心性的新方法，其中通过各个中心与整个城市系统的连通性来实现功能多中心性。本文通过针对芬兰三个功能性城市区域的城市空间结构的实证案例研究说明了该方法的潜力。在案例研究中，使用详细的通勤数据来衡量功能多中心的程度。
A shift from monocentric cities to increasingly polycentric urban regions has been widely recognised in recent research literature. Although polycentricity in general refers to the existence of several adjacent centres within the same area, many studies have emphasised that functional linkages between the centres of an urban system are also an essential part of polycentricity. Despite the increasing number of studies concerning functional polycentricity, research on the subject is still in a development phase. In this paper, a new approach to measure functional polycentricity is presented, in which functional polycentricity is approached through the connectivity of individual centres to the whole urban system. The paper illustrates the potential of the method with empirical case studies addressing the urban spatial structures of three functional urban regions in Finland. In the case studies, detailed commuting data are used in order to measure the degree of functional polycentricity.
