Odległość ekonomiczna w modelowaniu zjawisk przestrzennych z wykorzystaniem modelu grawitacji
Economic distance in modeling spatial phenomena with the application of gravity model

Summary/Abstract: The paper discusses the issue of an economic distance and its significance in modeling phenomena occurring in regional space. Economic distances between regions were determined and their influence on internal migration flows in Poland in the period 2000-2010 was examined. The period before Poland’s accession to the EU, as well as two periods referring to the changes in economic trend and the intensity of domestic migrations, was considered. The economic distance is one of the most significant determinants of inter-nal migration flows. In comparison to the geographical distance, it undergoes changes in time and space. Furthermore it affects the intensity of flows between regions in the opposite direction. Higher economic distance results in more intensive interactions between regions.
