Classify the developmental dynamics of newly built residential areas through residential mobility: Taking Wuhan city as an example

The improvement of land use performance in residential areas is of great significance to the efficiency of urban land use, the balance between work and residence, the allocation of public resources and the vitality of the social economy. However, there is still a lack of dynamic monitoring and evaluation methods for the land use performance of residential areas, especially effective monitoring means for the development of land use performance in newly built residential areas. Guided by the human-earth coordination theory and utilizing mobile phone signaling data, this study systematically investigates long-term temporal patterns of population migration through three analytical dimensions, dynamics, scale, and direction, while developing a dynamic evaluation model for assessing land use performance in newly developed residential areas. The development trend of land use performance in newly built residential areas in Wuhan can be classified into the following six categories: (1) Fast-heating and fast-stabilizing plots, mainly in Central and Northern Wuhan, are characterized by a rapid increase and subsequent stabilization of the static population. This is accompanied by declining immigration but a consistent net inflow, indicating that these areas are reaching maturity. (2) Slow-heating and stabilizing plots, predominantly located in the southern and western transition zones of Central Wuhan, exhibit a slow static population growth that eventually stabilizes a rise-and-fall pattern in immigration, and a volatile net inflow that eventually stabilizes, resulting in relatively late maturity. (3) Slow-developing plots, concentrated in Western, Northern and Central Wuhan, have an increasing static population, a gradual declining inflow population, and a net inflow that falls then stabilizes, resulting in a lagging development process. (4) Slow-heating and developing plots, scattered across Wuhan, characterized by a gradual increase in static population, followed by a later surge in immigration and a sharp increase in net inflow at a late stage, indicating strong development momentum. (5) Fluctuating development plots, found scattered in Southern and Western Wuhan, are marked by a rising static population, high volatility in both immigration and net inflow, and an overall unstable developmental trajectory. (6) Dynamically unstable plots, sporadically distributed in southwestern and southeastern periphery of Wuhan, have a low static population, are characterized by a low static population, high volatility in both immigration and net inflow, and slow development progress.
