Research on the Coupling Coordination Characteristics of Affordable Housing Market and Urban Development

Affordable housing development is an important livelihood project for promoting the harmonious development of the urban economy and society. However, the unclear spatial–temporal characteristics of the affordable housing market and urban development are not conducive to the promotion of regional urban sustainable development. Hence, it is of great significance to research the interaction characteristics between the affordable housing market and urban development to promote sustainable development. This study constructed an evaluation index system, coupling coordination model, and spatial econometric model of the affordable housing market and urban development to analyze the development level and spatial-temporal characteristics of coupling coordination between the two systems in 70 large- and medium-sized cities in China from 2010 to 2020. The results show the following: (1) From 2010 to 2020, the development levels of the affordable housing market and urban development rose with obvious regional differences. The development of the affordable housing market and urban development had the characteristics of spatial similarity and common development trends in the horizontal distribution and kernel density aggregation distribution. (2) The coupling coordinated development level of the affordable housing market and urban development in 70 large- and medium-sized cities in China from 2010 to 2020 was generally low, showing an increasing trend year by year, with significant regional differences. The coupling coordination level of the two systems in the eastern region was much higher than those in the central, western and northeastern regions. The spatial distribution characteristics showed a spreading trend from a high level in the east to a low level in the west. The coupling coordination development levels of the two systems had obvious positive spatial correlation characteristics. There were obvious differences in the coupling coordination development level of the two systems between the cities, which need to be comprehensively improved through interactions between the cities.
