Assessment of Interregional Inequality of Tax Revenues

Abstract

Efficiency of economic activity of 85 regions of the Russian Federation is analyzed in this article. The purpose of the research is assessment the interregional inequality of the Russian regions. The analysis was based on the total tax revenues collected within all the Russian regions. The research was based on methods of analysis and synthesis, analogy and generalization, comparison and comparison, induction and deduction, economic-mathematical and statistical methods of estimation of income inequality. For its implementation, coefficients and indices were used: Lorentz, Ginny, Robin Hood, Theil, Atkinson, and Herfindahl-Hirschman. Part of the analysis was performed in the analytical module of the information system “Taxes of the Russian Federation”. Based on the Russian Federation subjects’ economic activity model, it is concluded that the total tax revenues collected on regions reflect the effectiveness of its functioning. A more accurate picture is described with the quotient of the tax revenues’ division by the labor resources engaged in their creation. Based on the methods used and data provided by the Federal Tax Service of the Russian Federation and Rosstat, was made of the uniformity of tax revenue collection among 85 subjects of the Russian Federation in the period from 2015 to 2020, all applied coefficients and indices were calculated. Using the share of employed population and tax revenues, the Lorenz curves and size diagrams (box plot) for the ratio of these shares (r) in the period under consideration are constructed and the emissions (outlier) in the distribution of tax revenues are determined. The dynamics of tax revenues and their variation are estimated. The obtained values of inequality indicators and indices showed that the distribution of tax revenues among 85 regions of the Russian Federation is uneven. Simultaneously, this situation is evident throughout the period under review. The subjects whose tax income values can be attributed to outliers have been identified. It is concluded that the problem of uneven development of regions of the country is traced through centuries. A way out of this situation is to use differentiated financial and tax policies in relation to different regions of the country.
