The public administration sector is subject to constant change, with each change necessitating proper adjustments in both of its own organizational and functional areas, in order to optimally meet its publicly mandated tasks. In this article, an analysis has been made of public – private partnerships (PPP) which are most often seen as a form of execution of these public tasks, and to a lesser extent, attention is drawn to the partnerships as a tool for implementing change to the public administration itself. The authors of this article see PPP as an instrument aiming to redefine the role and scope of tasks which must be implemented by the public administration sector. Thus, the public sector as a result of actions taken up by it in the implementation of the public duties it has, determines its current role in society. The result of the analysis is the assertion that PPP enables changes in the public management model, which cause change transforming the public administration in the direction of an administration responsible for the fate of society as a whole, and not only publicly guarding the processes required in meeting the needs of the public, but actively defining these needs.
