上海市工作人群手机使用特征及对时空利用的影响

The Characteristics of Mobile Phone Usage Among the Working Population in Shanghai and Its Impact on the Utilization of Time and Space

信息技术快速发展推动着居民日常活动时空利用的重构。利用上海时间利用调查数据,运用多元线性回归分析法并估算其均值,探究了不同手机依赖度人群时空利用的差异。研究发现:①越年轻、学历和收入越高、居住在离市中心越近地方的办公室工作人群,对手机依赖越大。②极重度依赖手机人群全天高强度使用手机,而轻度、重度依赖手机人群的手机使用的节奏性更强。不同人群在居住地、移动空间中手机使用率相似,而在工作地、外出场所差异明显。③手机使用与部分群体的休闲、卫生护理和交通时间呈正相关,而与睡觉、工作、家务劳动时间呈负相关,对购物、社交、餐饮等活动时间无影响。④手机使用加强了工作、居住地的活动集聚效应,但未减少外出活动时间。研究结果以期加深对手机使用与居民日常活动时空关系及相应的城市空间运行的理解。

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:①The younger,more educated,and higher-earning office workers who live closer to city centers tend to be more dependent on their smartphones.②The 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.③Smartphone 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.④Smartphone 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.
