In this paper, we first present how one can create functional economic regions. Then, we elaborate on the economic activity and spatial interaction, which forms functional regions, and the development of the system of functional regions. Our presentation shows that the economy is structured in functional regions, and hence it is important to use functional regions in economic studies, in order to produce correct results, and for regional policy, in order for the policy to be effective. We observe, that the often used NUTS-regions are very large compared to the functional regions. We argue, therefore, that the use of NUTS-regions ought to be replaced by the use of functional regions. This would lead to more reliable results and better policy outcomes.
