In the years 2007-2013 the new member states were subject to much greater assistance from the EU budget than in 2004-2006. The main sources of financing of this aid are the Structural Funds (i.e. ERDF and ESF) and Cohesion Fund. Among the new EU member states the main beneficiary of these funds in the years 2007-2013 will be Poland. Recourses granted from the EU budget will be assign by the EU-12 states for: promotion of business, human resource development, development of transport, environmental protection and territorial development. Given the experience from previous years (i.e. 2004-2006) it can be expected that in 2007-2013 the use of aid funds will contribute to reducing disparities in the level of economic development that divides the EU-12 from the "old" countries.
