The article presents the results of the analysis of the impact of the National Development Plan (NDP) 2004–2006 and the National Strategic Reference Framework (NSRF) 2007–2013 on divergence/convergence processes taking place in Poland as well as between its regions and the EU average, measured as GDP per capita in PPS. The analysis was made using simulation results received by applying 16 regional HERMIN models and data as well as forecasts concerning NDP and NSRF transfers prepared by the Ministry of Regional Development of the Republic of Poland. The application of HERMIN models allowed the authors to make forecasts regarding the following macroeconomic indicators: GDP per capita (in PPS) in relation to the EU average and to the national average by 2020. The results indicate that NDP and NSRF implementation can accelerate the convergence process between the Polish regions and the EU average and slow down the weak divergence process within the country.
