Identification Method of the Russian Federation Arctic Zone Regions Statistical Aggregate as the Object of Strategy Development and a Source of Sustainable Growth

The lack of accurate identification of the territories belonging to the Russian Arctic zone is a specific feature. As a result, the problem of statistical observations of circumpolar regions arises. Russian Arctic zone is considered in an article in the format of the threshold spatial socio-economic entity. The identification of the regions included in the Russian Arctic zone is based on the concept of unstable aggregates. The probit regression tools are used to determine the thresholds and to form a threshold aggregates in the study. Equation parameter estimation is performed by a quasi-Newton method. The indicators that reflect a variety of criteria for classifying territories (municipalities) as the Arctic zone (based on not only geographical, but also climatic and biological criteria) were used as the initial data. These calculations allowed forming the list of territories identified as the Russian Federation Arctic zone.
