Abstract: In theory, skill-biased technical progress will reduce the importance of motor skills and emphasize the need for cognitive skills. Because men and women have different skill distributions, when technological advances cause relative price changes in different skills, the gender wage gap will also Change has occurred. The study used Chinese general social survey data and provincial-level technological progress data to empirically test the impact of technological progress on the gender wage gap. The analysis shows that technological progress, as measured by R&D investment, helps to narrow the gender wage gap. The same results have been obtained for the regression results by year, education level, occupational skill level, unit nature, and regional group. It is noteworthy that technological progress can help reduce the gender of the labor force with low education level and low professional skills. The key conclusions of this paper also passed the robustness test.
