O radu nadzornog odbora i uprave u kontinentalnom modelu korporacijskog upravljanja, odnosno upravnom odboru u američkom modelu, ovisi uspješnost poslovanja poduzeća. Stoga je sastav takvih odbora ključan te se na tu temu provode istraživanja s ciljem utvrđivanja optimalnog sastava. Spolna raznolikost spomenutih odbora u zadnje vrijeme dobiva sve veći značaj, ne samo zbog istraživanja kojima se dokazuje da je članstvo žena u takvim odborima pozitivno za uspješnost poslovanja poduzeća, već i zbog zakonskih zahtjeva, kojima se želi postaviti minimalna granica uz broj žena u takvim odborima. U ovom radu analizira se zastupljenost žena na upravljačkim pozicijama u hrvatskim poduzećima te istražuje utjecaj spolne raznolikosti u upravama i nadzornim odborima na uspješnost poslovanja poduzeća. Provedeno je istraživanje na uzorku od 400 najvećih hrvatskih poduzeća. Rezultati pokazuju mali postotak žena u upravama i nadzornim odborima hrvatskih poduzeća te kako se ne može sa sigurnošću tvrditi da spolna raznolikost u upravama i nadzornim odborima doprinosi uspješnosti poduzeća. Ipak, vidi se utjecaj spolne raznolikosti u nadzornim odborima na uspješnost poduzeća, što bi moglo biti predmet daljnjih istraživanja.; The success of the company’s business depends on the work of the Supervisory Board and the Management Board in the continental model of corporate management, and Management Board in the American model. Therefore, the stuff of such boards is essential, and various studies are being conducted on this subject in order to find out their optimal line-up. Sexual diversity of the mentioned boards is getting more and more significant, not only because of research which proves that participation of women in such boards has a positive impact on the success of the companies’ business performance, but also due to legal requirements, which aim to limit the minimum number of women in such boards. In this paper, we analyze the participation of women in managerial positions in Croatian companies and we research the impact of sexual diversity of the Management Board and the Supervisory Board on the success of the companies’ business performance. Empirical study was conducted on a sample of the 400 largest Croatian companies. The results show that there are a small percentage of women in the Management Board and the Supervisory Board and it cannot be considered that sexual diversity of the mentioned boards contributes to the company’s success. However, the impact of sexual diversity of Supervisory Board on the company’s success can be seen and that could be subject to the further research.
