As the pivotal phenomena in the ongoing globalization and localization, megaregions are just one of emerging spatial imaginaries at regional scales and have attracted considerable attentions in both academic research and policy relevance. One fundamental research agenda is whether the megaregional process is a consequence of polycentric development, or is being driven by a monocentric spatial organization. In view of this, this study establishes an unified analytical framework to comprehensively measure, classify, visualize and identify polycentric development of all megaregions in China. The megaregional polycentricity shows obviously divergence between morphological and functional dimensions. And no significant correlation exists between the morphological and functional polycentricity, which indicates the spatial mismatch between morphological and functional polycentricity of megaregions in China. Most of the megaregions perform less well in functional polycentricity and the most functionally polycentric megaregions are Pearl River Delta, Shandong Peninsula, and Yangtze River Delta. According to a typology of morphological and functional polycentricity, five types of spatial configurations of the megaregional process are classified and elaborated to better understand urban China.
