Entropy Parameters of Socio-Economic Resilience of Regions

The events of the past two years illustrate the most significant shock effect on the domestic socio-economic system. In this context deepening of territorial imbalances necessitated the development of differentiated approaches to formation of strategy and tactics for regional development. The solution of this problem is impossible without a perfect research of reaction features of regional systems on recessionary symptoms. The purpose of this investigation is the definition of entropy characteristics of the region socio-economic resilience as a response to shock disturbances of Ukrainian economy in 2013-2014. Socio-economic resilience is the ability of an economy (region) to withstand or recover from market, competitive, environmental, and other external shocks and to return to the path of growth. The economic structure of a region (structure existing activities) affects the exposure and vulnerability to different types of shock, and determines the robustness of local socio-economic system. Assessment of the economic structure involves determining both the overall structural diversification and parameter modularity, structural substitution and complementarity. Some shock impact on the socio-economic system is associated with the violation of existing relationships and the introduction of some "chaos". The entropy assessments of the region functioning were used for accounting this effect in this paper. It was modified Shannon entropy function and estimated the structural entropy level by economic activities for quantifying structural diversification of regions. Regional clusters are identified by the criteria of shock depth and the entropy change speed. According to the research regional features of the resilience response to shock disturbances are identified. The effects of modularity, structural neutrality, interregional substitution and complementarity are empirically confirmed. Framework to improve the information reliability of entropy parameters of socio-economic resilience are proponed.
