Modeling of financial support for the development of critical infrastructure objects

Topical issues of analysis and modelling of financial support for development of critical infrastructure objects are considered. The processes of reproduction of the national economy are considered within the framework of the matrix of financial flows (matrix of social accounts), which integrally describes the relationship between the markets and the institutional structure of the economy, makes it possible to allocate individual processes and conduct their analysis for criticality (profitability). The toolkit of these matrixes is taken as a basis for assessing the reproduction processes and identifying their criticality.To this end, a matrix of financial flows has been prepared, which has a block structure (goods and services, production and formation of income, financial flows, budgets of institutional sectors, gross investments, external sector), and generally includes 21 accounts, determining the reproduction processes under the scheme “GDP by income categories – net savings of institutional sectors”. The criticality of economic infrastructure is proposed to be assessed as the share of reproducing (gross, net) income in the structure of GDP, as the volatility of these incomes to GDP. Modelling of financial support for the development of critical infrastructure objects consists in the formation of internal conditions of economic growth – in ensuring the subjectivity of economic agents and the growth of national savings. Measures to improve the parameters of criticality in the processes of reproduction of economic infrastructure have been proposed. Methodological and informational sources of research were methodological provisions on national accounting and statistical materials of the State Statistics Service of Ukraine.
