Based on the analysis of the survey data from the Chinese Family Panel Studies in 2008(CFPS2008),this paper describes gender wage gaps in Beijing,Shanghai and Guangdong. The gender wage gap existed in each region and varied in different areas. By using the modified version of Mincer's human capital model,the shaping factors were found to be different in the three developed regions. Therefore,we should not regard all the developed areas as a homogenous entity in terms of gender wage gap.
