In recent years, scientific and practical interest in the strategic management of countries' financial development has grown significantly. However, an analysis of publications on this topic indicates the absence of a methodology to make strategic decisions on the formation of goals and priorities for financial development. The purpose of this study is to develop a methodology for the strategic management of the financial development of countries. The study uses methods of systemic, comparative, GEP analysis, and a rule-based judgment method. The result of the study is the development of a concept that allows defining strategy, quantified strategic goals and priorities for financial development, and its testing in OECD countries. The novelty of the research lies in the systematic approach to the formation of strategic goals and priorities based on the System of National Accounts, the multi-level system of key indicators of financial development, criteria formalizing alternative strategies, and rules for making strategic decisions. This is the first time such a concept has been proposed. The advantages of the developed concept are high representativeness, objectivity, and a wide range of applications. Its use will improve the quality of strategic management of countries' financial development and ensure transparency in government decisions. Doi: 10.28991/ESJ-2023-07-06-09 Full Text: PDF
