摘要：
peer effects on student outcomes are a crucial topic, but the reasons behind their significance remain unclear. while it is commonly believed that classmates aid each other, leading to better test scores, an alternative perspective suggests that lower-performing schools may have more disruptive behavior, resulting in negative peer effects. to address this, a seat randomization experiment was conducted in rural china, overcoming selection and reflection problems that hinder peer effect identification. the analysis indicates limited and inconclusive evidence of misbehaviors among peers significantly affecting test scores, likely due to strict disciplinary measures in chinese middle schools. additionally, controlling various measures of student behavior, the study finds that ability peer effect, measured by deskmates' test scores, have a notable impact on chinese test scores but not in mathematics. this suggests that classmates may not teach mathematical problem-solving skills and lack ability spillover in this subject. in the examined chinese schools, the main mechanism for the "ability peer effect" appears to be interpersonal comparisons. when a deskmate performs well academically, it motivates the student to study harder, resulting in improved chinese test scores, where effort matters more than ability or problem-solving skills.
