Abstract: This paper discusses the character of technological progress in the new era. Based on the character,this paper studies the relationship between technological progress and skill wage gap. According to the China's Employer-employee Matched Data,this paper makes an empirical study by OLS and treatment effect model. The findings are as follows:1. Technological progress in the new era is skill-biased. This type of technological progress affects the wage gap between high and low skilled workers mainly by changing the relative number and productivity of different skilled workers. 2. Skill-biased technological progress in enterprises will bring wage premium for both high and low skilled workers,but the premium degrees are different. The empirical results show that the hourly wage gap between high and low skilled workers has expanded by 5.94%. 3. Further heterogeneity analysis shows that technological progress enlarges the companies with limited liability and narrows the skill wage gap of employees in private-owned enterprises,which is mainly related to some factors such as enterprise scale,target,labor demand structure and so on. This study shows the existence of a certain wage gap is somewhat scientific and reasonable and that some necessary policy should be adopted to strengthen the vocational skill training for low skilled employees in order to fully deal with the impact of the new technological revolution on the labor market.

Key words: technological progress, skill-biased technological progress, skill wage gap
