Description
Population and construction land are the two most critical elements in the urbanization process. Their coordinated development is vital to the level and quality of urbanization. Studying the changes in population and construction land during urbanization is conducive to promoting the rational use of resources and sustainable development. With the increasing domestic and global macroeconomic downward pressure, changes in population structure, and industrial transfer, the unilateral growth of cities is no longer the only model of urban development. Cities have entered the post-growth era, and the phenomenon of urban shrinkage is common in both Western and Chinese cities. However, the evolution characteristics of population and construction land in China's urban contraction phenomenon have particularities different from those in Western developed countries, and they also face different development issues.
On the one hand, unlike the urban contraction phenomenon in Western developed countries that occurs in the mature stage of urban development, China's urban contraction phenomenon takes place during the rapid development cycle of urbanization. In recent years, the slowdown in China's urbanization growth rate will further exacerbate the urban contraction phenomenon. The transfer and mobility of the population continuously affect the allocation efficiency of urban construction resources. On the other hand, compared with the "double contraction" of population and construction land in Western developed countries, China more widely exists the contradiction of population contraction and construction land growth. The paradox of population loss and spatial expansion coexistence is an urgent problem to be solved in China's urbanization process. How the population-construction land in contracting cities changes, the degree of their disharmony, and the influencing factors are the main research questions of this research.
Therefore, this research first clarifies the uniqueness of China's contracting cities compared to the West. Then, it takes the county-level cities with contraction phenomena in China as the research objects, selects three time sections of 2000, 2010, and 2020, and deeply analyzes the spatial characteristics of the evolution of population and construction land. It uses the decoupling model to analyze the degree of development coordination, summarizes the coordination types and development trends of the human-land relationship in contracting cities, and analyzes the mechanism of action and influencing factors using the driving force-pressure-response model.
The research findings show that China's contracting county-level cities exhibit uneven regional distribution and different degrees of contraction. According to the decoupling model of human-land relationship and the characteristics of urban development, contracting cities can be classified into four types: resource depletion, environmental fragility, industrial transformation, and the suction effect around megacities. The city's own location and natural conditions, national institutional policies such as the household registration system and land policies, and local differentiated implementations such as economic development and facility support are the main factors causing the contradiction between population and construction land in contracting cities.
Based on identifying the spatial pattern of the evolution of population and construction land in China's contracting county-level cities, this study analyzes the degree of coordinated development and influencing factors of population and construction land. It proposes differentiated planning strategies for county-level regions with different types of contraction contradictions. This research has theoretical and practical significance for the efficient use of land resources in contracting cities during the post-growth stage, maintaining urban vitality, and promoting sustainable urban development. It also provides a certain reference for other developing countries in the process of urbanization worldwide.
