EXPORT AND IMPORT ACTIVITY OF THE VOIVODESHIPS IN POLAND IN THE CONTEXT OF THE SPATIAL CONCENTRATION MEASURED BY THE INDICATOR OF DIVERSIFICATION

Summary/Abstract: Purpose – The aim of the article is to diagnose the export and import activity of Polish voivodships through the prism of spatial concentration, and to investigate whether the import diversification index is the same as the export diversification index, and whether the diversification index loses its methodological value in determining both export and import activity of Polish voivodships due to the difficulties in assigning trade flows to a specific voivodeship.Reseach method – The article contains an analysis based on a review of the literature and calculations regarding the spatial concentration of exports and imports of Polish voivodships using the diversification index. The article uses the method of descriptive and explanatory research.Results – Presentation of the share of voivodeships in Poland’s export and import and the scope of spatial concentration measured by the diversification index in 1994–2019.Originality/value/implications/recommendations – The scope of spatial concentration of exports and imports expressed by the diversification index, in the analyzed period 1994–2019, did not change significantly, and the number of voivodships responsible for at least 75% of Polish exports was slightly higher than in the case of imports. At the same time, the importance of the ‘non-classified voivodship’ category increasing each year – almost 1/4 of Polish exports and almost 1/5 of imports are not assigned to any voivodship, which implies a decrease in the significance of the methodological value of the diversification index.
