This paper estimates the gender wage gap and its composition in China’s urban labor market
using the 2009 survey data from the Chinese Family Panel Studies. Several estimation and
decomposition methods have been used and compared. First, we examine the gender wage
gap using ordinary least square regression method with a gender dummy variable. Then, we
apply Oaxaca (1973) decomposition method with different weighting systems to analyze the
logarithmic wage differential. To be more specific, we prove the existence of sample selection
bias caused by the female’s labor force participation. We eliminate it by using the Heckman’s
two-step procedure. Empirical results reveal that male workers generally receive a higher
wage than female workers, and a great deal of this difference is unexplained. Meanwhile, this
unexplained part, which is usually referred to as discrimination turns out to be higher when
the adjustment is made for the selection bias. A further breakdown of the wage gap shows
that among all the individual characteristics, occupations explain the largest share of the
wage gap, followed by their working experience. On the other hand, education acts as a
contributor for discrimination in the labor market.
