This study uses data from a 2018 survey of 11,384 students in five Chinese provinces to investigate the peer effect on students' dietary and nutritional cognition. Children's eating habits have an important impact on their growth and health. Studies have shown that students' dietary behavior is mainly affected by their dietary and nutritional cognition. Therefore, studying the influencing factors of elementary school students' cognition of diet and nutrition has become an important research question. However, there are few discussions about the impact of peers' dietary and nutritional cognition on students' cognition of diet and nutrition. Consequently, this paper studied the peer effect on students' cognition of diet and nutrition. The results indicated that peers had a significant impact on the students' dietary and nutritional cognition. The endogeneity problem was solved using peers' parents' dietary and nutritional cognition scores and average educational level as instrumental variables. The impact of peer cognition on diet and nutrition was heterogeneous among different groups. The significance and degree of the peer effect differed based on peer relations, gender, age and school. The results indicated that in addition to family, school, teachers and other factors, peers were an important influencing factor.
本研究利用 2018 年对中国五个省份的 11384 名学生进行调查的数据，调查了同伴效应对学生饮食和营养认知的影响。儿童的饮食习惯对其成长和健康有重要影响。研究表明，学生的饮食行为主要受其饮食和营养认知的影响。因此，研究小学生饮食和营养认知的影响因素成为一个重要的研究课题。然而，关于同伴的饮食和营养认知对学生饮食和营养认知的影响，讨论较少。因此，本文研究了同伴效应对学生饮食和营养认知的影响。结果表明，同伴对学生的饮食和营养认知有显著影响。使用同伴的父母的饮食和营养认知得分以及平均受教育水平作为工具变量，解决了内生性问题。同伴认知对饮食和营养的影响在不同群体中存在异质性。同伴效应的显著性和程度因同伴关系、性别、年龄和学校而异。结果表明，除了家庭、学校、教师等因素外，同伴也是一个重要的影响因素。
