This paper estimates the causal effect of only-child status on educational performance among junior high school students from only-child and two-child families in China. It uses the dataset of the China Education Panel Survey 2013-14. The results show that the only children's educational outcomes are significantly low than students from two-child families. Only children's willpower and extraversion are weaker than children's from two-child families. The scale economies effect is strong and the resource dilution effect is weak when sibling size is small.
本文利用中国教育追踪调查（CEPS）2013-14 年的数据，估计了中国独生子女和非独生子女初中生教育表现差异的因果效应。结果表明，与来自非独生子女家庭的学生相比，独生子女的教育成绩明显较低。独生子女的意志力和外向性比非独生子女家庭的学生弱。当兄弟姐妹规模较小时，规模经济效应较强，资源稀释效应较弱。
