中文摘要
青少年智能手机使用的迅速上升引发了人们对其影响福祉与学习的担忧。本文利用行政数据和调查数据, 采用事件研究设计, 发现中学禁用智能手机对教育或心理健康没有平均效应, 但这一平均结果掩盖了重要的性别差异。禁令减少了女生对心理健康护理的使用, 降低了男女生的欺凌, 并提高了女生的平均绩点 (GPA) 与学业分流层次, 尤其是来自弱势背景的女生。这些结果表明, 智能手机禁令可以成为一项低成本政策, 用以改善结果, 尤其是对女生而言。
Abstract
<h3>Abstract</h3> The rapid rise in smartphone use among youth has raised concerns about its effects on well-being and learning. Using administrative and survey data with an event-study design, I show that banning smartphones in middle schools has no average effect on education or mental health but masks important gender differences. Bans reduce psychological health care use among girls, lower bullying for both genders, and improve girls’ GPAs and academic track placement, especially among those from disadvantaged backgrounds. These results suggest smartphone bans can be a low-cost policy to improve outcomes, particularly for girls.
