The theory supporting the concept is the theory of multi-level governance (MLG). The article analyses the process of implementation of this strategy and the macro-regional approach created in it. The analysis is related to 2019’s 10th anniversary of the creation of the strategy and the macro- regional approach, which was transformed into a concept implemented also in other macro-regions of the European Union.
