The article addresses the evolution of the e-governance model and its characteristics. The stages of the formation of the e-governance concept are analyzed, from the automation of bureaucratic processes to the systemic digital transformation of public administration. The differences between the concepts of "e-government" and "e-governance" are revealed, approaches to interpreting their essence by international organizations and in domestic legislation are characterized, and their role in the development of e-democracy is defined. The principles of e-governance include transparency, accountability, security, efficiency, convenience and simplicity of use, and scalability of solutions. The stages of the development of the e-governance concept in the world are outlined, and their dominant trends are characterized. The stages of maturity of the government's online presence according to the UN methodology are presented. Attention is focused on the fact that Ukraine is currently at the transactional level of e-governance development, while demonstrating high results in the citizen participation index and the maturity of open data. The four basic models of interaction between the state and key participants within e-governance (G2C, G2B, G2G, and G2E) are characterized, and their advantages are defined. The article notes that the G2C model is the most prioritized, as it is the one that most significantly affects citizens and determines the quality of their interaction with the state. Special attention is paid to the fact that e-governance is implemented through modern digital tools that help governments automate processes, provide services online, and improve interaction with citizens, businesses, and other institutions. The tools for the implementation of digital governance and their functional purpose at different levels of the management hierarchy are analyzed. The main tools include government service portals, electronic document management systems, electronic signatures, open data, online consultations and petitions, electronic procurement, and e-voting systems, which ensure the transparency and convenience of state processes. The article substantiates that the implementation of e-governance tools in Ukraine contributes to the modernization of public administration and the improvement of the quality of service provision, and at the same time, acts as an integral part of the country's European integration process and the alignment of the system of state and regional governance with the practices of the European Union.
