Abstract:

With the reform of China's urban housing system, relocation in cities is becoming increasingly more frequent. Analyzing the internal driving forces of residents of different age groups to move provides a basis for the improvement of urban living environment planning and construction. This study used multi-source data such as mobile phone signaling data in Wuhan City in 2019 and 2021 and took the life cycle perspective to identify the relocation frequency of residents of different age groups within the Fourth Ring Road of Wuhan City. This study proposed a model of relationship between the characteristics of built environment factors and the frequency of relocation, and explored the impact of various built environment factors in the residents' living circles on the relocation of residents of multiple ages. The study found that: 1) The moving in and out intensities of residents of different ages varied in different urban locations. Residents aged 19-39 moved more frequently than residents aged over 40. In general, the moving in and out intensity of the traffic areas within the inner ring road is high, and both are larger than those between the outer ring roads. 2) Relevant indicators in the dimensions of public service facilities, transportation convenience, and the living environment are important factors that caused residents' decision to move. Considering the differences in the relocation intensity of residents of different age groups and the characteristics of influencing factors, relevant planning decisions need to incorporate differentiated measures to improve the built environment, scientifically guide residents of different ages to relocate, and optimize urban population distribution.
