摘要:The aim of the study is to analyze and improve the system of theoretical and economic tools for diagnosis and ensuring financial and budgetary security. The scientific approaches to the disclosure of the concept of the mechanism of ensuring economic security, the most important part of which is financial and budgetary security, are investigated. The above mechanism in these works is studied only within the framework of the national level (macro level), while due attention is not paid to the study of this concept at the regional level (mesoscale). The article formulates the concept of “a mechanism for ensuring the financial and budgetary security of the region”, and also proposes a new diagnostic toolkit for indicators of financial and budgetary security at the regional level, which was tested on the example of the Kirov region.
