家庭劳动参与与高中生身心健康的倒U型关系——基于全国疫情期间高中在线学习状况调查数据的实证研究

Study on the Inverted U-type Relationship between Family Labor Participation and High School Students’ Physical and Mental Health:——An Empirical Study Based on the Survey Data of Online Learning Status in High Schools during the Outbreak of COVID-19

针对当下备受瞩目的劳动教育实践及其面临的价值危机和实践困境,本研究基于北京大学教育学院大数据中心在疫情期间开展的全国疫情期间高中在线学习状况调查数据,探讨了疫情期间家庭劳动参与的频率和时长与高中生身心健康水平的关系。研究发现:高中生的个人特征、家庭社会经济地位、行为特征都会显著影响其家庭劳动参与度。对高中生身心健康的影响方面,整体而言家庭劳动参与的频率与高中生身心健康水平呈现出倒U型关系,男生出现拐点的阈值比女生更低,且农村学生的家庭劳动参与与身心健康水平的关系并不显著。进一步地,分位数回归分析发现身心健康水平越低的高中生在家庭劳动参与中的获益越高。综上,研究表明家庭劳动参与本身具有高度的教育价值,但在开展过程中也需要因地制宜、因材施教。

Aiming at the current high-profile labor education practice and its value crisis and practical dilemma, based on the survey data of high school online learning during the pandemic conducted by the Big Data Center of Peking University Institute of Education, this paper discusses the relationship between the frequency and duration of family labor participation and high school students’ physical and mental health level. In terms of effects on the physical and mental health of high school students, as a whole, the frequency of family labor participation has an inverted U-type relationship with the physical and mental health level of high school students, where the threshold for turning points is lower for boys than for girls. However, the relationship is not significant for rural students is not significant. With further quantile regression analysis, we find that high school students with lower physical and mental health obtain higher the benefits from family labor participation. To sum up, the study shows that family labor participation has a high educational value but it also need to adapt to local conditions and teach students in accordance with their aptitude in the process of implementation.
