The purpose of this research is to reveal the relationship between women's education, women's labor force participation and national income in G20 countries. The relationships between women's education, women's labor force participation and national income were analyzed by the panel data analysis method for the G20 countries for the period 1997-2018. Stability of series were tested by "Fisher ADF" and "Fisher PP" panel root tests and the series were determined to be I (1). Pedroni (2004) was used to test the existence of cointegration relationships between the series. The series were found to be cointegrated. The long- and short-term relationships of the series were analyzed by the Panel DOLS method and it is determined that the increase of female schooling level increase the female labor force participation rate, increase of female schooling level and female labor force participation rate increase the per capita (real) national income. A two-way causality relationship was found between the ratio of women in higher education and national income per person. In addition, two-way causality relations between women's labor force participation rates and schooling rates at all levels of women were determined. In the study, it is concluded that in G20 countries, women's schooling rate increases the women's participation in the labor market and increases of women's schooling rate and female employment increase the national income per capita in countries.
