The influence of external institutional shocks on differentiation of the economic space of the Russian Federation

The article analyzes the influence of institutional shocks, caused by a radical change in the rules of external economic interaction, on the differentiation of the parameters of the regional economies and the economic space of the Russian Federation as a whole. The authors proposed and tested methods for analyzing the differences between the constituents of the Russian Federation in the context of typological groups formed by the criterion of susceptibility to external institutional shocks. The use of the basic Theil index for general (GRP) and private (foreign economic indicators) parameters of regional development, as direct indicators of the manifestation of shock consequences, allowed us to identify general and group shifts in the differentiation of the economic space and constituent entities of the Russian Federation. The final increase in the differentiation of the economic space within the analyzed period is substantiated, regardless of the direction of the shock effect, with the apparent resonance of the foreign economic parameters of the regions with an increase in this trend at the stage of strengthening institutional restrictions on foreign economic interactions. Particular attention is paid to regions susceptible to shocks, which made it possible to identify differences in the processes of adaptation of constituents of the Russian Federation of this group in post-shock conditions, which determines the need for a constant analysis of the scale and depth of consequences, taking into account the different levels of openness of the territorial areas of the economic space of the Russian Federation for the implementation of the national economy's Spatial Development Strategy to reduce the level of social and economic differentiation.
