Grawitacyjny model przepływów handlowych między krajami Unii Europejskiej w dobie globalizacji

The objective of the paper is to present the impact of globalization conditions on trade flows between states. These determinants were considered as alternative factors for the physical distance between countries in the gravity model performed by Tinbergen (1962). In the traditional gravity model a value of trade exchange between any of two countries is directly proportional to the product of their GNP and inversely proportional to the distance between them. In the current global economy geographical distance between regions is not identified as a factor of preventing a trade exchange; therefore the distance measure in gravity model may be interpreted as an economic dissimilarity of cooperating countries. In the paper the international trade flows between EU members in the period of 1999-2010 were examined. Panel gravity models presented in the literature prove that the globalization factors, apart from a geographical distance, perform a significant role for increasing international trade. The impact of improving transport infrastructure was confirmed in the study.
