Can daily mobility alleviate green inequality from living and working environments?

Urban green spaces are beneficial to residents' physical and mental health, but their spatial distribution is unequal. Green justice studies typically use static administrative areas as contextual areas to evaluate green spaces, which can lead to biased estimations, as it ignores daily mobility. However, the phenomenon that actual perceived green exposure may be averaged by daily mobility has yet to be tested. Based on a survey of Beijing residents' working, living, and daily travel environments, this study measures respondents' static and dynamic green exposure and tests whether dynamic green exposure intensifies or alleviates green inequality from living and working environments. The following results are obtained. (1) From the perspective of weekly travel, individuals living or working in a satisfactory green space environment have high levels of dynamic green exposure. (2) The difference in the amount of greenness of communities will lead to the further polarization of dynamic green exposure for trips beyond 2000 m from home. (3) When working in an environment with poor green space and street greenery quality, trips beyond 2000 m from the workplace will have high-quality and efficient dynamic green exposure. This study tests and reports on the disparity in dynamic green exposure under different static geographical backgrounds, which complements theoretical research on green justice.
