Abstract. In the context of our future development and integration into the European Union, the organizations are searching for new, attractive and advantageous solutions and ways of development. Most frequently they succeed in achieving their goals, a proof being their numerous innovative, original ideas which they put into practice and about which mass media keep us informed. In the global competition for markets, there is a need of strength and power. Therefore, the idea of "cluster" associations of organizations which, on the one hand, have common interests and, on the other hand, ensure the success of certain endeavors for society is among those actions initiated by firms in order to ensure the power that we have mentioned and a very advantageous position in the contemporary competitional frame.
