Romania belongs to the countries less developed in the European Union and the main desire is to reach the performance of the most developed countries. The β convergence is measured by the time needed to reach the desired level, in our case highest development level. The present study is calculating the β convergence for Romania at the NUTS0, NUTS1 and NUTS2 level with the most developed countries in European Union considering de annual average GDP/capita, considering as target value maximal and median values. The first issue we are looking for is the convergence existence among the European countries. The contribution of the study reveals the time needed to overcome the gap as a starting point for the strategies and the public policies design. In our opinion, a reasonable convergence time is a base for adjusting and speeding the existing policies, since a high period could be perceived as a need for disruptive measures. At the same time the study offers a perspective at the EU level about the time skyline of reaching the homogeneous regional development.
