The present paper approaches the notion of investment in order to demonstrate the necessity and importance of investments in an economy of transition, as it is the case in Romania and in a period of crisis, as it is the case of the current global economy. Through the evolution of investments in Romania and at the level of EU in the last years, we demonstrate that a high level of investments leads to economic prosperity, generally, in Romania the foreign investments having the effect of economic recovery. The performed research brought us definite arguments for the stimulation of foreign investments which would lead to the reduction of unemployment, inflation, to the increase of the products and services quality, i.e. of economy.
