The introduction of information and communication technologies is a priority for most economies as they take steps to reform their public administration; however, this requires considerable effort and is quite costly. The paper aims to verify whether and how the degree of maturity of e-government affects a country's quality of governance. The analysis was performed using correlation and regression analysis on a sample of European Union member states in the period from 2003 to 2020. In addition, bag plots were used to provide graphical interpretation. The analysis proved a relationship between the degree of utilisation of e-government and the quality of governance. The implementation of information and communication technologies has had a positive effect on the evaluation of the quality of governance in the analysed countries.
