Intra-industry Trade in an Enlarged Europe : Trend of Intra-industry Trade in the European Union and Its Determinants

In this paper I examine the evolution of intra-industry trade (IIT) in intra-European trade in the period of accession of the Central and Eastern European countries (CEEC). In order to identify changes in IIT in intra-European trade, I calculate the Grubel and Lloyd index for the static dimension and Brülhart A index for the dynamic dimension. Based on Grubel and Lloyd index, I conduct gravity-type empirical tests to verify determinants of IIT at the intra-European level. I find that CEECs experienced considerable increase in IIT, particularly during transitional periods before their accession. However, the level of IIT between CEECs is still considerably low. Given that a trade-investment nexus exists to explain IIT in intra-European trade, IIT in CEECs can increase further, as they receive more FDI from their neighbors
