Moreover, according to the most
recent data, the measure of the extent of integration indicated that the level of economic
integration between regions in Romania is gradually increasing. There is a big difference
between the NUTS 2 and NUTS 3 interregional integration; therefore it is necessary to
investigate the regional development on the lower regional level. Furthermore, small
differences between indicators of integration in counties and development regions mean that
development regions in Romania represent a correct economic activity. The increase of integration indicator between the Romanian NUTS 2 and NUTS 3 regions suggests that
effectiveness in reallocating resources within the country is also increasing.
Promising areas for further research can be regarded as the answers for the two
questions: 1) how integrated are the national economies of other EU member, which joined
the Union in 2004 and 2007; and 2) how does the EU membership impact the level of internal
economic integration in Romania and the other new member states.
