The author proposes a method for measuring technological competition among businesses and a method to determine the structure of technological competitiveness. To this end the author uses the CCR super-efficiency model applied in Data Envelopment Analysis (DEA). The proposed procedure is used in the study of technological competition among Poland's 25 largest banks. He uses a set of 2006 data published by Polish banking trade magazine 'Miesiecznik Finansowy Bank' in June 2007. The results obtained by the author show that foreign and private banks generally display the greatest potential for technological competition, while some of the banks that were spun off from the National Bank of Poland (NBP) at the start of the country's transition to a market economy are the least capable of being competitive technologically. The same is true of banks controlled by state-owned enterprises and organizations.
