Womens political participation is a prominent symbol of their status. The participation of professional women in urban institutions is of great significance to other female groups in exemplification and guiding. Our research shows that age, political status, political efficacy, smooth degree of political participation channels, the frequency of contacting mass media, and degree of cognitive factors on the legal protection of political participation have a significant impact on professional womens political participation in urban institutions, but the educational level has no significant effect on their political participation. So raising the awareness of political participation of those women, establishing a legal and orderly political participation channels, and strengthening the publicity and popularization ability of the mass media, etc. can promote their political participation.
