TRENDS IN THE DEVELOPMENT OF THE DIGITAL ECONOMY IN THE REGIONS OF THE RUSSIAN FEDERATION

The article presents the genesis and stages of the digital economy development. The object of the study is the subjects of the Volga Federal District (PFD) of the Russian Federation. The subject of the study is determined by the assessment of the state and development of the digital economy using the tools of the Boston Consulting Group matrix and the grouping of statistical measurement indicators for 2005-2019. The chosen analytical tools made it possible to diagnose the level of digitalization of the economy: to determine the degree of digitalization of the region at the current moment, to identify regions with similar trends, to find best practices that allowed some regions to reach the forefront. The obtained indices are combined into a summary indicator, the results of which allowed us to divide the subjects of the Volga Federal District into 4 groups: "depressed", "lagging", "stable", "progressive". The resulting typology of the regions of the Volga Federal District will allow us to develop specific measures in the field of regional digital policy and accelerate the processes of digital transformation of the regions and the country as a whole. Among the regions of the Volga Federal District, the IT sector is developing most successfully in the Republic of Tatarstan, the Perm Territory and the Nizhny Novgorod Region. These regions are implementing a consistent and most effective digitalization policy, which creates the basis for the successful development of the economy and social sphere.

CORRELATION AND REGRESSION ANALYSIS OF THE AUTOMOTIVE GASOLINE MARKET

Purpose of the study: to identify the factors affecting the volume of production of motor gasoline. Research methods: analysis and synthesis, systematic approach, as well as methods of correlation and regression analysis. Results of the research: A methodological approach to the use of tools for correlation and regression analysis of the gasoline market is proposed, which includes the following stages: 1) formation of a data array; 2) carrying out correlation analysis, building a correlation matrix, selecting factors into the model using the Correlation tool in the Data Analysis package of MS Excel; 3) conducting a regression analysis, constructing a regression equation, substantiating the obtained dependence using the "Regression" tool in the "Data Analysis" MS Excel package, calculating the elasticity coefficients. It is proposed to use the volume of production of motor gasoline as effective in carrying out the correlation-regression analysis and constructing mathematical models. Among the dependent variables and factors affecting the volume of production of motor gasoline, it is proposed to use variables that characterize four groups of factors: resource (raw material) limitations (the volume of oil production and refining), production capabilities of the industry (through the depth of oil refining and the yield of light oil products that characterize production capacity and set of installations in the industry), price attractiveness of the market (prices of producers and consumers of motor gasoline, world oil prices), export attractiveness (volume and value of exports). Multivariate economic and statistical models of the dependence of the volume of production of motor gasoline on a number of factors have been developed. Based on the results of calculations, a strong correlation was revealed between the volume of production of motor gasoline and the values of primary oil refining, oil production, and export of motor gasoline. The predicted values are located as close as possible to the residual values, which indicates that the resulting regression equation has a high degree of accuracy. Research prospects: the research results can be used to identify significant factors in the development of the motor gasoline market in the Russian Federation.

CORRELATION AND REGRESSION ANALYSIS OF THE EFFICIENCY OF THE USE OF INVESTMENT RESOURCES OF AN OIL COMPANY

The result of the formation and use of investment resources of enterprises is characterized by many parameters and the relationship between them and the results is usually unknown. As a result, it is advisable to use economic and statistical methods and models, in particular, methods of correlation and regression analyzes, when analyzing the efficiency of using investment resources. The article substantiates a methodological approach to the use of correlation and regression analysis in modeling indicators of the efficiency of using the investment resources of an oil company. By the efficiency of using the investment resources of oil companies, we mean the ratio of income received from the investment activity of an economic entity and the costs associated with ensuring this activity. It is recommended to use the method of correlation and regression analysis to assess the influence of factor indicators on the effective indicator (an integral indicator of the efficiency of using the investment resources of an oil company). Based on the calculation of the integral indicator for a number of periods, the dynamic change in the efficiency of the formation and use of investment resources of the oil company is estimated, which allows characterizing the qualitative state of the management system for the formation and use of investment resources of the oil company. A one-factor economic and statistical model of the dependence of sales proceeds, sales profit, net profit and sales profitability on the integral indicator of the efficiency of using the investment resources of an oil company has been developed. The proposed methodological approach was tested on the example of the oil company PJSC «Gazprom Neft». A moderate correlation between the net profit indicator and the efficiency of the formation and use of investment resources of an oil company is revealed. It was found that if the integral indicator of the formation and use of investment resources changes by 1 %, the net profit will change by 31.56 %. Based on the results of the calculations, the main directions of increasing the efficiency of using the investment resources of the oil company are proposed, the implementation of which will allow maintaining the valuesн of the integral indicator of the effectiveness of the formation and use of investment resources of the oil company PJSC «Gazprom Neft» at a high level.
