Access to education, especially elite education, is believed to be one of the most
important channels for elite formation and social mobility in modern societies. While
there is a burgeoning literature estimating the returns to elite education, little empirical
investigation exists on how the access to elite education affects elite formation and
social mobility. In this paper, we not only estimate the returns to elite education but also
attempt to understand their implications on elite formation and social mobility using a
large-scale dataset we collected ourselves in China.
接受教育,特别是精英教育,被认为是现代社会精英形成和社会流动的重要渠道之一。虽然
有越来越多的文献预估了精英教育的回报,但很少有实证研究表明,接受精英教育的机会是

Every year, around 10 million students in China take the National College Entrance
Exam – the largest standardized test in the world – in order to get admitted by
around 2,000 colleges of different tiers. The exam not only determines whether a young
person will attend a Chinese university, but also which one – attending an elite
university is perceived to have a crucial bearing on career prospects or to provide a
ticket to the elite class (Wong 2012). This perception is not without controversy: due to
the importance of family background for the labor market, some argue that it is illusion
rather than reality that the exam system can provide upward mobility and change one’s
fate (Bregnbaek 2016).
每年,中国约有 1000 万学生参加全国高考——世界上最大的标准化考试——以获得约 2000
所不同层次的大学的录取。高考不仅决定了一个年轻人会否进入中国大学,还决定了他能进
入哪一所——进入精英大学被认为对他的职业前景至关重要,是为他提供了进入精英阶层的
入场券(Wong 2012)。这种看法并非没有争议:由于家庭背景在劳动力市场的重要性,一些
人认为,考试制度可以提供向上流动性并改变一个人的命运,这是错觉而非现实(Bregnbaek
2016)。
The exam-based admission of Chinese colleges provides us a Regression Discontinuity
(RD) type laboratory to understand the role of elite education. We define elite
universities as those designated by the Chinese government as the first-tier universities
in admission. Elite universities have a cutoff score, and students just above and below
the cutoff score are similar in most characteristics, but those above are admitted into
elite universities. Thus, we could simply compare outcomes (income and other variables)
of students who are just below and above the cutoff score, which solves the typical
empirical issue that students entering better universities may be different in ability,
family background and other characteristics. We should note that even though the score
is the main criterion, it is possible that some students with scores below the cutoff get
accepted with extra points from minor criteria such as talents in art and sports. It is also
