In an environment where international competitive conditions are becoming increasingly difficult in parallel with the changes in science and technology, the importance of developments in information technologies is increasing day by day. This study aims to specify the relative efficiency of European Union countries in the field of information technologies using Data Envelopment Analysis. In this direction, four inputs and four outputs are determined. According to both the CCR and BCC models, Austria, Croatia, Czechia, France, Germany, Lithuania, Poland, Slovakia, Slovenia, and Spain are the countries that cannot show 100% performance in obtaining information technology outputs with the information technology inputs determined in the study. While Belgium and Poland are effective in the BCC analysis, they are not effective in the CCR analysis. In this case, Belgium and Poland are technically effective in BCC analysis, but can not achieve scale efficiency. Input and output rates of inefficient countries are interpreted by comparing them with best practice benchmarks.
