Exploration of "Urban Contraction" from the Perspective of Urban Development—In the Case of Nantong

Abstract

Under the background of the rapid revitalization of the country, the population in some parts of China is declining, which is called urban contraction. With the universalization of the phenomenon of urban contraction, it is a link of polarization and structure in the process of reconstruction, which also affects and social development. Different from the absolute contraction under the background of recession in traditional industrial cities and the adjustment contraction under the background of functional spillovers in metropolises, the contraction of small and medium-sized cities in non-core cities of agglomeration is more manifested in the liquidity contraction under the background of competition. This paper, taking Nantong, Jiangsu Province,China, as an example , from the perspective of urban development concept ,tries to analyze the extent and duration of population contraction and the trend of population structure change in the medium-sized cities .Then summarize the characteristics of phenomena in small and medium-sized cities in non-core cities of agglomeration and explore the formation mechanism of phenomena according the reasearch results on contraction and the incremental results of its economy and land use. Finally, Combining with the research results of scholars at home and abroad, this paper considers the opportunities for the transformation of values and methodology behind the phenomenon of urban shrinkage and seeks the sustainable development of cities behind the crisis.
