Analysis Of Gender Wage Gaps In China Based On Big Data Technology

Gender equality is not only one of the Sustainable Development Goals of the United Nations,but also a basic national policy of China’s social development.Gender pay gap is a relatively intuitive and very important part of gender equality due to its direct reflection of the difference of economic status in the labor market.Combining computer science and social economics,this thesis studies the status quo of gender pay gap in China by using large-scale Chinese resume data of online job seekers,and provides possible solutions from the supply side and the demand side respectively.The main contents and major contributions of this thesis are summarized as follows:（1）Combining computer science with traditional social statistical methods and statistical physical methods,this thesis constructs an analysis model of gender pay gap,and observes and analyzes the influence of macro and micro factors on gender pay gap in China.The results show that the average wage of women in China is only 71.57%of that of men.The gender pay gap is widespread in all age groups and education groups.In general,developing education,economy and changing cultural prejudice are routine and effective ways to reduce the gender pay gap.However,the resume data shows that the above methods have been very limited in narrowing the gender wage inequality in China,that is,China seems to be stuck in a bottleneck where traditional methods cannot make further progress.（2）On the supply side,this thesis combines large-scale resume data with traditional statistical data to analyze occupational gender segregation.The result shows occupations with higher proportion of men have smaller gender pay gap.The thesis further shows that the severity of occupational segregation in China is low both overall and regionally,and the inter-occupational discrimination is much smaller than the intra-occupational discrimination.Accordingly,the thesis suggests Chinese women a new way to narrow the gender pay gap:to join male-dominated occupations,and there are not large barriers,although it does not mean that the gender discrimination is smaller in these occupations.（3）On the demand side,further analysis of large-scale resume data finds that the part which the human capital can not explain（suspected "discrimination"）accounted for 81.47%of the gender pay gap in China.And the thesis finds that the gender pay gap of the married group is larger than that of the unmarried group,while the proportion of suspected"discrimination" is significantly larger（increased from 72.54%to 86.80%）.The results related to marital status prompt the thesis to turn from the traditional theory of human capital to the theory of family constraints under the current predicament,and provide some new policy suggestions to solve the gender wage inequality and improve family support from new findings and perspectives.
