Development of information and communication technologies (ICT) has recently increasing importance. ICT has therefore become one of the effective tools in process of optimization and increase of competitiveness on the market. As a result of this trend, there are already some studies, having ambitions to explicitly formulate their importance. The application of ICT in the Czech Republic is similar, but there are not many studies with such ambitions. This thesis analyzes (i) the relations between, the use of ICT, total factor productivity and growth of gross added value in the Czech Republic in 1997-2007 based on growth accounting and (ii) based on econometric analysis of panel data for the Czech Republic, also estimates the importance of selected determinants influencing adoption of ICT. The output of the thesis consists of (i) determining the contribution of each input and discussion of possible synergies of ICT capital deepening and total factor productivity and (ii) specification of variables that are, based on the formulated model, shown to be statistically significant and they may affect the adoption of ICT.
