Why the Gaokao Is More Like a Tournament Than an Exam, According to Harvard Economists

Tournament

China’s education system is described as a centralized hierarchical tournament . Centralized means the central government sets curricula, enrollment quotas, university rankings, and exam dates. Hierarchical refers to a pyramid of institutions: the two “double‑first‑class” universities (Peking and Tsinghua), then the top‑9, top‑40, top‑100, followed by ordinary undergraduate and vocational colleges. Gaokao scores allocate students into these layers, making placement effectively irreversible.

The tournament model from labor economics applies: participants’ rewards depend on relative rank, not absolute performance. Winners receive a reward far larger than losers, inducing maximal effort from all. In the Gaokao, admission is based on a student’s score relative to peers in the same province, and the payoff gap between elite and ordinary universities is cliff‑like.

Empirical data show that university education yields an average 40 % income premium, and graduates of elite schools obtain an additional ≈40 % premium. Admission to a top‑100 university raises the probability of obtaining a government job by 33 %, granting stable employment, housing subsidies, quality healthcare, urban hukou, and school‑placement rights for children.

Why Rational Families Bet Everything

Chinese families allocate roughly 17 % of household income to children’s education—about five times the global average. High‑school students add ≈27 hours of extracurricular study per week on top of regular class time.

The authors formalize the incentive with an expected‑return model: Expected payoff = p·R_elite + (1‑p)·R_common – C(e) where e is effort, p is the probability of elite admission, R_elite and R_common are the respective rewards, and C(e) is the cost of effort. The first‑order condition shows that a larger reward gap ( R_elite – R_common) raises the equilibrium effort level, explaining the observed high study intensity.

The model also reveals an efficiency problem: when all participants increase effort, each individual’s winning probability does not improve because the denominator (total competitors) grows proportionally, while total societal preparation costs keep rising—a classic prison‑er‑dilemma structure.

In 2024, 13.42 million students sat the Gaokao, but only about 0.5 million slots were available at the top‑100 universities (under 4 %). The vast majority accept lower‑tier placements, yet society bears the collective cost of preparing for those limited elite slots.

Fairness Assessment

On the surface, the Gaokao appears objective: a single national (or provincial) paper, admission based on scores, no interviews, recommendations, or extracurricular bonuses. This provides a visible form of “fairness”.

Data, however, expose systematic disparities:

University enrollment: urban 51 % vs rural 35 %.

Extracurricular tutoring: urban students receive four times more tutoring than rural peers.

Family income: the richest 25 % earn about 14 times the poorest 25 %.

Education spending share: poorest families devote 57 % of income to education, richest families 11 %.

Elite‑university entry: children from the top 20 % of families are 2.3 times more likely to attend elite schools than those from the bottom 20 %.

For comparison, in the United States affluent families’ children are 11 times more likely to attend elite colleges. Thus, while the Gaokao is not devoid of fairness, its fairness is systematically over‑estimated, which helps legitimize the system.

After University

Study effort drops sharply after university admission: weekly extracurricular study falls from about 27 hours (plus 45 hours of class time) before the Gaokao to roughly half that amount for university students.

Chinese freshmen start with higher learning intensity than global peers, but after four years many stagnate or regress. The tournament logic explains this pattern: the Gaokao is the endpoint, not the starting line. Twelve years of preparation optimize exam scores; once the goal is reached, the incentive disappears, and the degree functions more as proof of past effort than as a driver of continued learning.

Implications

The authors argue that the Gaokao has historically provided a genuine upward‑mobility channel for low‑income families and has underpinned China’s economic growth, contributing roughly one‑third of growth over recent decades. Simultaneously, it operates as an “over‑burning” machine, generating substantial, unrecoverable collective costs while delivering opportunities.
