Justification of the identification of threats and problematic components of sustainable regional development in the security dimension

The issue of substantiation of the problematic components of sustainable development in the security dimension and threat identification methodology is investigated. The methodology consists of directly combining the identification of threats with the need to observe the limits of the safe existence of dynamic economic systems, which connects the problem of sustainable development with the problem of security. The explanation of the extended homeostatic plateau, which explains the conditions for the transition to a higher technological system, or the complication of functioning and the loss of the main functions of the existing technological system, has gained further development. A theoretical substantiation of the limits of secure existence in terms of security gradations is proposed: critical, threshold, and optimal on both sides of the “extended homeostatic plateau”. Quantitative values of security gradations are associated with the extension of the “t-criterion” method for the formal determination of bifurcation points for characteristic types of distribution, that is, threats. The identification, classification, and analysis of problematic components and critical threats at the level of components and indicators were carried out, which made it possible to identify only four strategic directions of institutional measures that allow covering almost all indicators of sustainable development at the regional level.
