Although Poland has managed to maintain high growth levels since the mid-1990s, with the second-best performance in the OECD in 2006-07, territorial disparities are persistent and rising, especially between large urban areas and rural ones. Like many OECD countries, Poland must seek to achieve an appropriate balance between support for poles of growth and the development of lagging regions, particularly its eastern peripheral regions, which are among the poorest in the European Union. This report explores the various challenges and opportunities for Polish regional development policy, and provides recommendations to best design and implement the policy mix, looking in particular at governance challenges.
