Comprehensive Classification of Urban Agglomeration Types in China

Abstract

Urban agglomeration is not only an important carrier of China's new urbanization strategy, but also a new regional unit for the country to participate in global competition and international division of labor. At present, China's regional spatial governance model is undergoing a major change, from the original administrative division management to the type of regional spatial governance. Based on the important extension characteristics of urban agglomerations, this paper classifies 23 urban agglomerations in China with the idea of comprehensive classification, and obtains the index system and clustering results of type classification, which provides scientific basis for the planning guidance of spatial pattern optimization and classification management of urban agglomerations in China. Referring to the scale and degree of agglomeration of mature urban agglomerations in the world, based on the four characteristics of urban agglomerations, the index system is constructed. Fuzzy C-means clustering (FCM) method is used to quantitatively classify Chinese urban agglomerations into five types.
