Given the importance of trade performance to overall economic fundamentals,
the question arises as to the extent that South East European Countries
(SEEC) have successfully followed the successful transition path of Central
and Eastern European Countries (CEEC). To address this issue, we use
similarity indicators to calculate possible convergence between the export
structures of SEEC and CEEC from 2007-2008 to 2018-2019. We then compute the
value of the similarity coefficients of SEEC and CEEC export structures and
compare them with EU import structures, and intra-industry trade for both
SEEC and CEEC. Next, we calculate the qualitative changes of both SEEC and
CEEC merchandise trade through the tendency of technology-intensive
products. The results of these two groups are compared to determine whether
SEEC trade performance is converging to that of the CEEC. The results show
structural improvements and an above-average increase in SEEC trade since
2007. However, given the simultaneous, moderate qualitative trade progress
in the CEEC, the convergence between these two groups is insufficient to
close the gap in the foreseeable future.
