Resumen
The polycentric urban structure is regarded to be more rational than the monocentric structure in recent urban studies. However, challenges have emerged in the implementation of the polycentric strategy accompanying with rapid urbanization in developing countries. The concept of polycentricity need to be re-examined in the developing context and the performance of polycentric urban development need to be further quantitatively assessed. This paper attempted to fill the research gaps and established a general framework for evaluating intra-urban polycentricity based on China’s context. The measurement of morphological and functional polycentricity as well as the relationship between them were explored based on urban big data. Using the case of Shanghai, it was found that the functional subcenters identified by mobile phone communication data are not always consistent with the morphological subcenters recognized through land development. The development of functional polycentricity (e.g., urban functional linkages) generally lags behind that of morphological advancement (e.g., physical urban expansion). Both socioeconomic and planning forces have significantly shaped the polycentric pattern of Shanghai. Policies that aimed to promote the further development of polycentricity are also proposed.
