The phenomenon in difficult employment of female college students is a complex social problem with multiple social factors interweaved.Analysis of the structure of supply and demand in economics can be used to explain this appearance，but it is lack of convincing in understanding the gender discrimination against women.The gender discrimination during the employment of female college students can be divided into two parts，one is caused by the market economy and the system itself and the other is by the social norms of gender roles.The first one can be relieved by a sound market system of rules，but the existence of the latter shows that the traditional gender order has still restricted the female behavior，conversely，the reactions on restrictions of the female individual have reproduced the gender order of the society.
