Polish regional economic disparities have been the subject of debate in the government and European Union since the early 1990's. These differences can be attributed to the location of input factors, whose origins can be traced back to the divergent development paths pursued by partitioning powers and also to the later management of the country's economic resources up until the beginning of the 1990's under communism. The Socialist system of economic planning, given its reliance on heavy industry, largely reinforced economic structures across regions, resulting in the central, southern and western areas of the country becoming more industrially concentrated, while regions further east remained largely agricultural and less developed in terms of infrastructure. This two-tier pattern of development originally resulted in east-west regional inequalities, giving rise to the division of the Polish map in socio-economic terms into "Poland A" and "Poland B" (Szot, 1999).
