Identifying Brazilian functional regions: a network approach, 1980–2010
利用1980、2000和2010年巴西城市间通勤数据，通过网络分析方法识别出反映主要城市经济辐射范围的功能区域，为区域分析和规划提供替代性地理划分。
This paper seeks to identify functional regions that reflect the contiguous spatial economic reach of major Brazilian urban centres. We use data from commuting to work and study between municipalities and apply network analysis methods for the periods of 1980, 2000 and 2010, aiming to find regions with the maximal internal consistency of their commuting flows in each period. Our results provide functional regions that serve as an alternative geographical division for Brazil, with the advantage of broadening the scope for regional analysis, policies and planning.
