摘要：In this paper, we investigated the level of competitiveness of the processed food sector of the Danube region countries, in order to show the existence of comparative advantage and the correlation of exports. We used the Balassa (RCA–revealed comparative advantage) index and TPI (trade performance indexes). At first, using the Pearson and Spearman index, we examined the existence of correlations between the processed food sector of the Danube countries. Then, we applied the Least Significant Difference (LSD) test to further compare the value and answered the question: between which Danube countries are there significant differences? With the study, we found that the distribution of the RCA index in Bosnia and Herzegovina, Hungary, Moldova and Slovenia deviates from normality. We also found the existence of a strong correlation of the RCA index of the Czech Republic with Romania, Hungary with Moldova and Serbia, Moldova with Serbia and Bulgaria with Ukraine. Finally, we concluded that the development of trade in the countries of the Danube region requires the participation of all relevant interest groups and could play an important role in providing faster economic development, that is in achieving sustainable development of the countries, with the sustainable use of available resources.
