教育作为人力资本投资和国家经济能否在长期中取得成就的重要一环，其收益问题一直是教育经济领域研究的重要问题。尽管长期以来有大量的学者使用过多种方法对教育的收益进行估算，但是大量的因教育而来的外部收益和非货币收益被忽略掉了。本文使用 Probit 模型，分别用父亲学历、母亲学历以及父母平均受教育年限衡量父母的受教育程度，研究父母教育水平对子女在高中阶段就读于重点中学的概率，发现均有着显著的正向的影响。

Education as an important part of human capital investment and whether national economy can achieve success in the long-term, the issue of income has always been an important issue in the study of education economy. Although a large number of scholars have long used a variety of methods to estimate the benefits of education, a large number of external benefits and non-monetary benefits from education have been ignored. The Probit model used in this paper measures parental education level with father's education, mother's education, and parent's average years of schooling to study the probability of parental education for children in key middle schools in high school and finds that they have significant positive results.
