We calculate the labor force participation rate using "Japan Doctoral Human Resource Profiling". The rate of female doctor under 35 years old is 95.8%, which is remarkably higher than general college graduates and above. However, the career development would not be favorable, because the rate of the female doctoral candidate to actually get a doctoral degree is about 5 points lower than male and the female non-regular employment rate is higher than male. Having investigated the influence of the family formation on the rate of getting the degree, it was estimated that the rate of getting the degree fell down in the case of the woman who has a child.
In addition, when the regular employment rate was taken as the dependent variable, a negative coefficient was estimated for both married women and women who have children in cases where employers were universities and private enterprises.
