||The analysis of Czech exports and imports with the European union shows that it is the rise in exported quality that is one of the reasons of the successful growth of the Czech foreign trade in the past few years. Detailed study based on the approximation of quality by unit values of exports and imports demonstrates that in majority of Czech exporters prevails competitiveness by lower prices on European market. At the same time there are signs of growing importance of quality as a competitiveness criterion as well as its rising success (measured by values of turnover and trade balance). The importance of increasing quality and technological position of a country proves its positive impact on the country’s trade balance and economic development. On the first sight this is reflected in higher values of trade, it must be based in the future on increase in technological level and value added. Czech foreign trade with the EU countries remains (despite its positive trade balance) unbalanced with respect to quality of imported and exported goods, but the development shows decreasing values. Differences between the imported and exported quality are based on the character of the goods traded; whereas the imports of quality are dominated by the goods with higher value added (and therefore higher unit values), the Czech strongest exporting industries are rather typically goods with lower unit values.
