摘　　要：本文基于中国西北农村调研数据,运用倾向得分匹配方法,分析农村儿童兄弟姐妹的数量对其心理健康状况和学业表现的影响。研究发现,随着儿童兄弟姐妹数量的变化,"交流互动"和"资源稀释"两种相反机制在同时发挥作用。当兄弟姐妹较少时,"交流互动"的作用更明显,相对于独生子女,有一个兄弟姐妹的儿童在心理健康状况和学业表现方面表现出一定优势;当有较多兄弟姐妹时,"资源稀释"的作用更明显,因此有两个或两个以上兄弟姐妹的儿童在心理健康状况和学业表现方面均显著差于有一个兄弟姐妹的儿童。This study evaluates the effect of sibling size on children＇ s mental health and academic performance using Propensity score matching method. The data is from a large-scale survey in western rural China. We find that owning siblings implies two kinds of effect： interaction and resource dilution. When children have two or above siblings, the limited resource in their family will be diluted by their siblings, thereby children with only one sibling have better mental health and academic performance relative to children with two or above siblings;when children don＇t have any siblings, they will lost the chance to interact with their siblings and then learn from this interaction, thereby children with only one sibling also have better mental health and academic performance relative to children without siblings.
