In 2007-2013 Poland will be the main beneficiary of structural assistance from the EU's general budget. The main sources of the financing of this assistance will be the structural funds (the European Regional Development Fund and the European Social Fund) and the Cohesion Fund. Assistance means awarded to Poland will be used to finance the implementation of five national operational programmes, 16 regional operational programmes and European Territorial Co-operation Programmes. It is expected - basing on the experience of other EU member-states, especially Ireland, that the use of EU assistance in Poland will exert an influence on the improvement of basic macroeconomic indicators such as investments, employment, unemployment, productivity, foreign trade, etc. A synthetic expression of changes occurring in the Polish economy will be an increase in the rate of economic growth. The use of assistance funds should as a result help diminish the difference between the level of social-economic development in Poland and in the 'old' EU countries.
