【摘要】 理解并识别高等教育中同伴效应的大小、性质和机制对高等教育政策的制定、实施、评估，以及高校在群体环境中有效地组织管理学生至关重要。基于中国东部某“双一流”建设高校本科生数据，利用随机分配室友的自然实验，考察了大一学生学业成绩的宿舍同伴效应。研究发现，平均意义上室友学习能力对个人大一学业成绩的影响不显著；但不同学习能力的学生受室友的影响不同，中学习能力学生对室友学习能力构成变化敏感，高、低学习能力学生受室友学习能力构成变化的影响不显著；随着入学时间的增加，学生会受到与本人家庭经济条件不同的室友的显著负影响。更多还原

【Abstract】 Understanding and identifying the size, nature and mechanism of peer effects in higher education is essential for the formulation, implementation, and evaluation of higher education policies, as well as for the effective organization and management of students in a group environment. Based on the data of undergraduates in a “Double First-Class” university in eastern China, the natural experiment of randomly assigning roommates is used to investigate the roommates’ peer effects on freshman’s academic performance. The research found that, on average, roommates’ academic ability has no significant impact on individual freshman’s academic performance; however, students with different family economic conditions are affected differently by roommates, students with medium academic ability are sensitive to changes in the composition of roommates’ academic ability, while students with high and low academic ability are not significantly affected by changes in the composition of roommates’ academic ability; as the enrollment time increases, students will be significantly negatively affected by roommates who have different financial conditions from their families.更多还原
