DIGITAL TRANSFORMATION OF INSTITUTIONAL AND ANALYTICAL SUPPORT FOR PUBLIC FINANCE IN THE CONTEXT OF THE INNOVATION ECONOMY

Introduction. In the current context of the digital transformation of society, there is a growing need to rethink the role of public finance as a tool not only for fiscal regulation but also for strategic development. Traditional models of budget administration are proving insufficient to ensure transparency, accountability and efficiency in the management of public resources. At the same time, the rapid development of digital technologies, such as blockchain, big data, and artificial intelligence, opens up new opportunities for modernizing the financial system. In this context, the study of the digital transformation of public finance is extremely relevant, as it meets the challenges of the innovation economy and the need to increase trust in public administration. Methods. The methodological basis of the study is a combination of systemic and structural-functional approaches, typological analysis, case method and visualization methods. The empirical basis is based on examples of the implementation of digital platforms in public finance in Ukraine, Georgia, the Baltic States, and Canada. The chronological scope of the study covers 2015-2024. The source base is formed on the basis of data from open budget portals, regulations and international reports (IMF, World Bank, OECD). Results. The article presents a classification of digital solutions into four generations: from open data portals to blockchain platforms with smart contracts. A comparative analysis of the functionality, legal integration and scalability of the OpenBudget, ProZorro and GovChain platforms is carried out. Discussion. The results obtained can be used as an analytical and methodological basis for further research in the field of digital design of budget ecosystems, as well as for the development of regulatory approaches to the integration of decentralized technologies into public financial management. Keywords: public finance, digital transformation, blockchain, smart contracts, ProZorro, OpenBudget, GovChain.
