The impact of electronic services for citizens on the efficiency of public administration extends beyond simply digitizing bureaucratic processes. It has a positive effect on various aspects of management, ultimately increasing value for both society and the state. The purpose of the article is to quantify the degree of influence that electronic services have on several factors characterizing the public administration efficiency, utilizing the following methods: correlation analysis, factor analysis, multivariate regression, and radar method. The study found a relationship between the development level of electronic services (measured by the E-Government Index) and various indicators of public administration efficiency. The findings showed that e-government can account for approximately 57.1% variation in these indicators, but it is important to take into consideration the significant value of the standard estimation error. The study's novelty lies in its comprehensive approach to examining the various aspects of public administration efficiency regarding the development of electronic services for the population, as well as their quantitative characteristics. Further research areas will be aimed at an in-depth investigation of e-governance's impact on sustainable development and international efficiency indicators.
