Strategies of Residential Area Regeneration and Urban Development in China from the Perspective of Mismatch between Population Mobility and Land Supply: Take Shenzhen as Example

Objectives: After the global financial crisis in 2008, the housing price in cities of China turned from comprehensive prosperity to regional differentiation, and the phenomenon of coexistence of “high housing price” in some cities and “high inventory” in some other cities appeared. The problem of mismatch of land resources and population mobility in China has generated superimposed effect on the high housing price and high inventory in different areas, and the outbreak of COVID-19 in the world has also brought new challenges to the urban development modes; thus, how to develop mega-cities to guarantee the residents’ welfare has become an important academic issue and practical issue. In this paper, with Shenzhen, the most representative city in China, as an example, typical characteristics of real estate market in cities are analyzed, and the methods such as field investigation, questionnaire survey and behavior observation are adopted to analyze the conflicts between the spatial environment of the old residential areas and the demands of residents from the perspective of man-land mismatch. On the basis of expounding the corresponding relationship between the residents’ actual demands and the space, the intergeneration-integrated age-appropriate community regeneration strategy is proposed, and the corresponding suggestions on improving the residents’ welfare are proposed from the perspectives of aging of population, architectural space and urban development. This paper concretely reflects the real estate policy of “one policy for one city”, and proposes new thinking for the development of resilient cities in the post-epidemic era.
