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.
Highlights
Under the background of economic globalization, urban agglomerations have become the most dynamic and potential growth point in a country's economic development, and a new regional unit for the country to participate in global competition and international division of labor
This paper starts from the divisional management of China's regional space governance mode from the divisional management of administrative districts to the need of space management according to type zones
The study of type division provides a scientific basis for the implementation of spatial pattern optimization and classification management planning for local urban agglomerations in China
Summary
Under the background of economic globalization, urban agglomerations have become the most dynamic and potential growth point in a country's economic development, and a new regional unit for the country to participate in global competition and international division of labor. Many scholars use a combination of qualitative and quantitative methods or GIS spatial analysis techniques to define the spatial extent of urban agglomerations. In general, domestic and foreign scholars still focus on the classification of urban agglomerations in the qualitative division stage. A few quantitative studies are mainly based on a single feature dimension, and there are few studies on comprehensive quantitative division from multiple dimensions. Based on the main extension features of urban agglomerations, comprehensive classification ideas are used to integrate 23 urban agglomerations in China.
