In this paper we examine the innovative performance of Greek firms in terms of female participation in research and technological development. We rely on the final results of a research project on women in innovation, technology and science, based on 372 questionnaires selected on a two years time period (2004-2006). For this reason a number of variables are used, like the total number of women employees by age, education level, firm size and sector, as well as women in product and in process innovations.
