Foreign direct investments (FDI) are the engine of the economic development in the developing countries, but also in the high developed ones. FDI played an important role in the Central and East -European countries integration in the world economy; these former communist countries had non efficient economies, and at the beginning of the transition they did not had the physical and financial capital, necessary for the reorganization and economic growth. The FDI distribution in these countries was not equal, and their impact for some of these economies quite low. Romania registered low values until 2003, because of the slow rhythm reforms and economic and political instability. The business environment, the incentives, the economy stability led to a very high volume of FDI starting with 2004, tendency maintained after the E.U. accession of Romania.
