In the present study the way in which the gender wage gap in urban China differs according to marital status, education and occupation, is examined. Married Chinese women experience much larger absolute gender wage gaps than their unmarried counterparts. The proportion of the gender wage gap unexplained by differences in the levels of productive characteristics is also higher for married women than single women. Gender wage gaps are smaller for more educated women. These findings suggest that occupational segregation is not as important a factor as industrial segregation in accounting for the gender wage gap in China’s urban labour markets.
