Spatial Distribution of EU Structural Funds in Poland in 2004-2006 - Factors, Directions, and Limitations In 2004, Poland joined the European Union. This access means the possibility of taking advantage of European Union Structural Funds. Apart from this the structural funds play another important role. The popularity of the idea of European integration in countries like Poland depends largely on the effectiveness of this financial support, which theoretically should lead to economic and social development on different levels (local, regional, national, and even continental). The main problem of relying on EU funds is their unequal availability, which is limited, for example, because of the granting principles. PUBLICATION ABSTRACT
