Abstract:

Under the background of promoting urbanization construction, with county towns serving as an important carrier, and integrated urban-rural development, with counties serving as the basic unit, scientifically identifying the contraction status and type of urban development of county-level units has become critical to its urbanization development classification policy. This study constructs urban development evaluation indicators with “population-land-economy” coupling interactions, identifies and classifies the urban development status of human activity entities in counties and county towns with the help of a quadrant map and coupling coordination model, and uses geographic detectors to discuss factors. Taking 62 county-level units in the Gansu section of the Yellow River Basin in China as examples for empirical verification, the results are as follows: (1) Most county-level units in the Gansu section of the Yellow River Basin have developed well, including 14 county-level units that have contracted in counties and 21 county-level units that have contracted in county towns, and most contractions are related to supply-side reform and deindustrialization. (2) The number of county towns of absolute expansion or absolute contraction in the region is more than that of counties; the urban development in each county town is unbalanced; the differentiation of increase and decrease is severe. (3) The level of social and economic development and the quality of life of people are important factors affecting the urban development of counties in the Gansu section of the Yellow River Basin, and the vitality of local development and the intensity of development and construction are important factors affecting the urban development of county towns. (4) The interaction law of the leading factors between the counties and county towns is manifested as contraction>expansion, and the combined effect of multiple factors is conducive to the improvement of the contraction development trend of the counties and county towns. A quadrant map based on the urban shrinkage type screening method is proposed, and the empirical results can provide a basis for the planning and construction guidance of county-level units in the Gansu section of the Yellow River Basin.

Key words: county-level unit, urban development level, coupling coordination level, quadrant map, Gansu section of the Yellow River Basin
