Using the panel data of 31 provinces during 1993-2005, this paper examines the factors that influence wage changes in China. During the process of the marketization, the linkage between wage and some factors such as inflation, productivity and unemployment rate has been strengthened. But there still exists large room for further development of labor market, as the relationship between the wage and productivity is not sufficiently strong, and the wage’s response to the unemployment is lagged. The wage forming mechanism in different regions also varies. The econometric results show that, contrary to some public perceptions, the eastern areas’ wage marketization is not satisfactory.
