Visegrad economies' active implication in a "new" EU: A new regional economic approach.

The EU faces maybe to the greatest challenges in its history. The paper deals with the idea of analysing the sub‐regional organisation Visegrad Group Visegrad 4 (V4) and its role in the new EU‐27 before and after Brexit. For realisation of this scope, six representative economic indicators are taken into consideration. The data analysis procedure covers latest 10 years meaning 2010–19. In order to support the analysis in the paper, first objective has the building a hypothetic optimal database which has to cover the above six indicators related to EU‐28 and V4. Second objective is relate to the performances quantification of each EU and V4's economy based on a separately analyse. Final and the major objective is that V4 is able to face to the new global and regional challenges. The analysis in the paper is based on two new models. First of them is a regional development radiography model based on a hexagon diagram. The second is a regional evolution model based on a matrix approach. Both proposed models have distinct hypotheses, which are finally valid by the analysis. The paper puts into discussion five objectives and succeeds in achieving them. The main conclusion of the paper is that V4 is and will continue to be a growth pole for the EU economy. It would be supported by the EU in order to implement policies able to manage better employment. [ABSTRACT FROM AUTHOR]
