本文通过对中国287个地级以上城市的行政区域和中心城区就业中心的识别和考察，分析了城市多中心性。研究发现，中国大多数城市在其行政区域内都有多个就业中心，中国城市的多中心空间发展明显。然而，这一结论取决于所讨论的空间尺度，因为大多数中国城市在其城市地区仍然具有单中心的城市形式。中国城市的空间发展趋势与理论预期和西方城市演化的趋势是一致的。然而，我们的研究也揭示了中国城市多中心空间发展的一些独特特征。例如，行政区域的空间结构比城市地区更加多中心;中国城市多中心的出现更多地与制造业的分散化有关。城市郊区化和中心城区以外的外围地区的发展促进了行政区域内的多中心发展，但抑制了城市区域内的多中心发展。这些发现突出了规划和政府干预在中国多中心城市发展中的主导作用。
This paper analyzes urban polycentricity for 287 Chinese cities at the prefecture level and above, by identifying and examining employment centers within both their administrative regions and central urban areas. We discover that the majority of Chinese cities had more than one employment center in their administrative regions, and the polycentric spatial development is evident in urban China. However, this conclusion is dependent on the spatial scale under discussion, since the majority of Chinese cities still had monocentric urban forms in their urban areas. The spatial trend of Chinese cities is consistent with theoretical expectations and that of Western urban evolution. Nevertheless, our study also revealed some unique features of polycentric spatial development in Chinese cities. For example, the spatial structures in administrative regions are more polycentric than in urban areas; the emergence of polycentricity in Chinese cities is more linked to the decentralization of manufacturing industries. Suburbanization and more development in the outer region beyond the central urban area contribute to the polycentric development in the administrative region but restrain the polycentric development in the urban area. These findings highlight the predominant role of planning and government interventions in the polycentric urban development of China.
