The article discusses the issue of studying the measured quantitative values (indicators) of criminalization of economic relations in detail. One of the main problems of counteracting the criminalization of the economy lies in its unbiased measurement. This issue is particularly relevant in the modern world, since the need to measure the criminalization of the economy is reflected in the strategic planning documents of the Russian Federation. The purpose of the study is to justify the need to measure the criminalization of the economy and criminalization of financial and economic activities of commercial organizations (hereinafter “FEA CO”) in their entirety. The obtained goal is achieved using analytical, formal-logical methods, as well as the method of correlation analysis. The authors concluded that the monitoring based on mining and processing of objective quantitative values (indicators) should be a priority mechanism of economic security, as the lack of such evaluation makes it impossible to efficiently counteract the criminalization of the economy. The article analyzes the degree of study of the problems of indicator measurement of criminalization of the economy and FEA CO and assesses monitoring as a tool of the economic security mechanism. The authors determined the place of the indicator measurement of criminalization of the economy when using it and concluded there is a need to differentiate the indicator “level of criminalization in the field of FEA CO”. There is a high correlation between the criminalization of the economy and the criminalization of FEA CO. As a prospect for further research, it is noted that the study of the phenomenon of criminalization of the economy can not be reduced only to the analysis of the statistical data. Their use is necessary for conducting criminometric studies, the purpose of which is to find links between the criminalization of the economy and FEA CO with other economic, legal and social categories. The results obtained can find practical application in the activities of information and analytical centers of the Ministry of Internal Affairs of the Russian Federation, as well as in planning the activities of Internal Affairs bodies related to counteracting the criminalization of the economy.
