ESTIMATION METHODOLOGY OF INTERREGIONAL DIFFERENTIATION OF ECONOMIC SPACE
The article is dealt with economic and social development of the regions on the basis of progressive structural shifts in sectoral, spatial and functional systems, restoration and strengthening of effective cooperation of regions, reduction of inter-regional disproportions, sustainable use of economic potential of each region and improvement of legal and institutional base of regional policy. It is noted that indicators of economic activity of various regions indicate a deep structural imbalance in the system of national economy; There is a significant differentiation between regions in terms of the gross regional product structure, differentiation according to the results of industrial activity, differentiation of territories according to the level of social and economic development and living standards of the population and disproportion in the budget provision of the subjects of the Russian Federation. We consider different approaches to the evaluation of interregional differentiation here. When examining the differences between the regional economies, it is proposed to use a comprehensive approach that allows us to assess not only the differentiation in different directions of the social and economic state of the territories but also the structure of these differences. It is proposed the estimation technique including: definition of the optimal set of indicators reflecting the main aspects of economic and social development of the regions (industrial, innovative, social and labor components); the choice of statistical characteristics on the basis of which the assessment will be made; identification of differences between regions in the above areas; analysis of the significance of the differences using the Ryabtsev index and identification of factors for smoothing differentiation in each of the regions. We propose to use the range of interregional asymmetry, the variation of regions and the coefficient of regional asymmetry as the coefficients for assessing interregional differentiation. It is proposed to carry out an analysis of the materiality of interregional differences using the Ryabtsev index. It is completed an estimation of interregional differentiation between the regions of the Central Federal District by the index "Index of industrial production by subjects of the Russian Federation". It is performed the analysis of the materiality of inter-regional differences in the indicator "The share of innovative goods, works, services in the total volume of shipped goods, performed works, services" between the Kursk region and the subjects of the Central Federal District. It was noted that dynamics is observed to reduce interregional asymmetry, gradual smoothing of differentiation between the regions of the Central Federal District occurs.
