In the conditions of transformative transformations of the domestic macroeconomic environment, which is associated with the challenges of military aggression, the need for relocation and business recovery, a decrease in the standard of living, and high flows of population migration, it is expedient to determine financial mechanisms for ensuring effectiveness in conditions of economic instability. The formation of the European integration vector of the development of the economy of Ukraine determines a significant

role in the implementation of European standards to ensure the competitiveness of the national producer in foreign markets. Solving the issues of post-war recovery and entering new E.U. markets is a top priority for Ukrainian businesses. Financial mechanisms determine the basis for the formation of investment attractiveness, entrepreneurial activity, and competitiveness. The article analyzes financial mechanisms at the level of the macro- and microeconomic environment. The analysis and grouping of financial support of business entity models made it possible to determine the direction of the research. Forecasts of the financial system development were developed based on the definition of realistic pessimistic, and optimistic scenarios. The methods of implementation of financial mechanisms and their specifics are analyzed, and the resulting indicators are modeled as factors for evaluating the influence model. The analysis of the practical implementation of financial mechanisms and their effectiveness at

the enterprise level made it possible to select the key parameters for ensuring the competitiveness and development of national enterprises in the conditions of challenges and transformations. As a result, the authors developed methodological principles for forming and implementing financial mechanisms that can ensure effectiveness and competitiveness at the level of business entities.
