Digital transformation has become a prevalent feature of the twenty-first century, extending from business to all aspects of social life. Public administration has also been affected by this trend. However, no country undergoing a transition economy has been capable of matching the level of digitalization reached by developed nations. The study aims to evaluate the digital transformations of public administration in transition economies and assess their impact on indicators of population well-being, standard of living, and governance efficacy. The research methodology utilizes various methods, including comparison, grouping, correlation, regression, and cluster analysis, to evaluate the efficacy of digital transformations in public administration within transitioning economies. This article evaluates the extent of digital transformations in public administration and uncovers their favourable progress in countries with transitional economies from 2010 to 2020. An insignificant direct relationship (determination coefficient R2 ≍ 0.15) has been demonstrated between E-Government Development and Index GDP (Gross Domestic Product) per capita. However, a positive, strong connection between E-Government Development and the Government Effectiveness Index has been found. Countries with transitional economies were categorized into four clusters based on the degree of digitalization in their public administration. Results showed that there were no noteworthy gaps between the clusters, as most of the examined countries had comparable levels of development, experience and abilities in the digitalization of public administration.
