The rapid development of information technology has driven the reconstruction of the spatio-temporal utilization of residents'daily activities.This study utilizes Time Use Survey data from Shanghai and employs multiple linear regression analysis to estimate its means,exploring the differences in spatio-temporal utilization among populations with varying degrees of smartphone dependence.The findings are as follows:① The younger,more educated,and higher-earning office workers who live closer to city centers tend to be more dependent on their smartphones.② The group with extreme smartphone dependence uses their phones intensively throughout the day,while the light and moderate dependence groups exhibit a more rhythmic pattern of phone usage.The smartphone usage rates are similar in residential areas and mobile spaces,but differ significantly in workplaces and outdoor locations.③ Smartphone usage is positively correlated with leisure,healthcare,and transportation time,but negatively correlated with sleep,work,and housework time,with no impact on shopping,social activities,and dining time.④ Smartphone usage has strengthened the agglomeration effect of activities in work and residential areas,but has not reduced the time spent on outdoor activities.The research results aim to deepen the understanding of the relationship between mobile phone usage and the spatial-temporal aspects of residents'daily activities,as well as the corresponding operation of urban spaces.
