新冠疫情改变了全球人民的生活方式，包括但不限于生活观念，卫生习惯，和行为方式等。限制社交距离作为最有效的疫情防控措施之一，其所带来的全球移动性的降低和个人活动空间的缩小是显而易见的。面对疫情封锁过程中出现的主观幸福感降低的现象，亟需从应对的视角出发，考察疫情封锁是否改变了人们的手机使用行为，以及何种手机使用行为会对个体的主观幸福感造成影响。

本研究主要关注高校学生这一群体主要有两大原因。其一是因为许多高等院 校在疫情期间采取了“非必要不出校”的封锁措施，这使得校内学生的日常活动 空间受到了限制。其二是因为高校学生的年龄较轻，对于特定状况下的应对缺乏 经验，而 青少年时期的负面经验会在此后的人生阶段中造成持续性的影响。

本研究围绕手机使用和移动性这两个概念，梳理传播学、心理学和交通运输研究等领域中有关其与主观幸福感之间关联的文献。在此基础上确认了本研究考察手机使用的两个维度，即可供性——使用手机所达成的实践类型，和移动模式——手机使用与物理移动之间的关系。其中前者包括信息性、社交性、娱乐性、创造性、和效率性手机使用；后者包括替代型、修改型、增强型、和中立型移动模式。同时，由于实际的物理移动性遭到限制，本研究提出感知移动性这一概念，考察其与个体的手机使用以及主观幸福感之间的潜在关联。

本研究结合经验取样法和问卷法，对99名符合条件的高校学生进行为期一周的实证调查，共收集有效数据点3612个，其中属于未封校群体的有2325个，属于封校群体的有1287个。为考察封校组与未封校组之间的差异、各关键变量间的关系、以及手机使用及感知移动性是否影响主观幸福感，本研究对样本分别进行了独立样本T检验，相关性检验，以及混合线性模型的建立。

实证研究表明，校园封锁仅对主观幸福感的情绪维度造成负面影响，而对认知维度无显著影响；封校组与未封校组的手机使用行为存在显著差异；感知移动性始终正向预测积极情绪及负向预测消极情绪，但在封校组中与任何手机使用行为都无关；在所有类型的手机使用行为与对应的移动模式中，娱乐性使用负面影响积极情绪，而修改型移动模式正面影响消极情绪。

通过考察疫情下校园封锁对高校学生手机使用行为的影响，并进一步在手机使用行为与主观幸福感之间建立关联，本研究确认了疫情下移动模式在手机使用中的重要性，并首次将其与主观幸福感相关联。同时，本研究在实践上对其他移动性受限的群体也具有启发和借鉴意义。

The COVID-19 Pandemic has changed people’s lifestyles around the world, including but not limited to their mindset, hygiene habits, and patterns of behavior. As one of the most effective pandemic prevention and control measures, limiting social distance has brought about a reduction in global mobility and personal activity space. In the face of the decline of subjective well-being during the epidemic blockade, it is urgent to examine whether the pandemic lockdown has changed people's mobile phone use behavior and whether, and if so, what kind of mobile phone use behavior will affect individual subjective well-being from the perspective of coping.

There are two main reasons for this study to focus on college students. One reason is that many colleges and universities have taken the lockdown measures of "not leaving school without necessity" during the pandemic, which has limited the daily activity space of students in the school. The second reason is that college students are young and lack experience in coping with specific situations, and the negative experience of adolescence will have a lasting impact in later life stages.

Focusing on the two concepts of mobile phone use and mobility, this study combed the literature on the relationship between mobile phone use and subjective well-being in the fields of communication, psychology, and geography. On this basis, it is confirmed that this study examines the two dimensions of mobile phone use, namely, affordances - the practice type afforded by mobile phone use, and mobility patterns - the relationship between mobile phone use and physical mobility. The former includes informational, social, entertaining, innovative, and efficient mobile phone use; The latter includes substitution, modification, enhancement, and neutrality mobility patterns. At the same time, due to the limitation of actual physical mobility, this study proposes the concept of perceived mobility to examine its potential relationship with individual mobile phone use and subjective well-being.

This study combined experience sampling methods and survey method to conduct a one-week empirical survey of 99 eligible college students, and collected 3612 valid data points, including 2325 belonging to the non-lockdown group and 1287 belonging to the lockdown group. In order to investigate the difference between the non-lockdown group and the lockdown group, the relationship between the key variables, and whether mobile phone use and perceived mobility affect subjective well-being, this study conducted independent sample T-tests, correlation tests, and the establishment of mixed linear models for the samples.

The empirical study showed that campus lockdown only negatively affected the affective dimension of subjective well-being, but had no significant effect on the cognitive dimension; There was a significant difference in mobile phone use behavior between the lockdown group and the non-lockdown group; Perceived mobility always positively predicted positive emotions and negatively predicted negative emotions, but it had nothing to do with any mobile phone use behavior in the lockdown group; Among all types of mobile phone use behaviors, entertaining phone use negatively affects positive emotions while modification mobility pattern positively affects negative emotions.

By investigating the impact of campus lockdown on college students' mobile phone use behavior during the pandemic, and further establishing a relationship between mobile phone use behavior and subjective well-being, this study confirmed the importance of mobility patterns in mobile phone use during the pandemic and associated it with subjective well-being for the first time. At the same time, this study also has enlightenment and reference significance for other groups with limited mobility in practice.
