Discussions on the importance and opportunities of the public-private partnership have been taking place for many years. The article presents an analysis of public-private partnership which is usually considered a form of realisation of public tasks.

In their article, the authors emphasise the specific role that public-private partnership can play in designing public sector policies, and its application related to the lack of funds for effective realisation of public tasks. Public-private partnership allows then for changes in the public management model, by transforming public administration towards administration that is responsible for the whole society.
