Abstract. The paper presents data on the influence of the most significant factors having impact on the credit portfolio volume, as well as conducts correlation and regression analysis with the subsequent construction of the trend for a short period. Credit activity is understood as the bank activity in the formation of a credit portfolio. Considering the structure of the bank credit portfolio, it can be observed that it consists of credits granted by the bank particularly for legal entities, individuals and other banks. Herewith, it is necessary to understand that any decrease in the credit portfolio will adversely affect the financial stability and effectiveness of any commercial bank. Moreover, during crisis periods, the policy and practice of banks have been determined as quite aggressive and conducted as such with regard to interest rates. The dynamics of credit portfolio volume has been selected as an independent factor due to the reason that it can fully explain the current development situation and the effectiveness of the bank credit policy. Considering the dependent factors, their influence will be assessed by the credit portfolio volume indicator. The authors have distinguished the following ones among them: the volume of credits granted to individuals; the volume of credits granted to legal entities; the amount of overdue credits in the credit portfolio; bank investments in the securities; inflation; key rate. IntroductionThese days, it is necessary to apply the economic and mathematic method of multiple correlationregression analysis for identification of relationship between the credit portfolio volume and the factors affecting this indicator. The model development required involvement of the data for the period of 2012-2016 from the publicly available information sources of Russian statistical organizations and analytical groups. In order to determine the dependence of the volume of the credit portfolio on various performance indicators of the bank, it is necessary to build a regression model and analyze the quality of these models. For calculation of the paired correlation coefficients matrix, let us use the "Correlation" program of the MicrosoftExcel "Data Analysis" menu.Then, using the Regression program of the MicrosoftExcel Data Analysis Add-in menu, let us get the data and regression analysis coefficients. The results of the analysis and calculations of regression statistics are summarized in Table 2.The data obtained allow one to assess primarily the reliability of the model on the basis of coefficient analysis, and also to assess the influence of each factor of the model for the immediate forecasting of each factor, respectively, and then to forecast the volume of the credit portfolio itself.

In this paper, we consider the structural dynamics of foreign direct investment that entered the Russian economy during the period of 2009-2015. In this regard, the main forms, methods and instruments of foreign direct investment were presented and the main areas of investment were highlighted. The study consisted of several stages and was based on the data published on the official websites of YUNKTAD, IMF, CBR. Leading countries on foreign direct investment attraction, the strategies and the methods for investment attraction were studied, the major sources of investment and the countries of origin were identified. In 2014-2015 20 countries were revealed, which were the leading ones in terms of foreign direct investment attraction, including the United States, Hong Kong and China. High investment values were observed among the countries that are leaders in the number of mergers and acquisitions (US). The priority areas of investment are engineering, information and medical technologies, biotechnologies. A special feature of foreign direct investment structure accumulated in Russian Federation by investor countries is the significant role of offshore investments. The share of Russian Federation in the global inflow of foreign direct investment decreased to 0.6% in 2015 against 3.7% in 2013.

This paper considers the problems and dynamics of investment activities of enterprises in the Russian economy. In the current context oil and gas companies have got in to a challenging situation against the background of their competitiveness in the world market. Balance between supply and demand has been changed in the course of shale revolution in the United States, due to Iran’s coming back to the world’s oil market and “market share retention” policy being pursued by the countries – OPEC members. The paper specially consider Tatneft, since it plays an important part in the national, economic, political, public and social life of the Republic of Tatarstan. The Company’s stable operation in strategic raw materials extraction, its budgetary and hard-currency injections warrant progressive and harmonious development of the Republic. The most important factor for the investing activity it the international agreements of cooperation in oil and gas sector.

This article considers the problems of infrastructure financing, which is necessary for the successful development of regional economic systems. To identify the current problems in the development of investment attractiveness of the Russian regions, we selected the following factors: availability and level of provision of industrial, social, transport, and other infrastructure with facilities, government expenses on the creation and development of regional infrastructure. The study consists of several stages and is based on data published on the official websites of the World Bank, Gazprombank, the Ministry of Economic Development of the Russian Federation, and the Ministry of Regional Development of the Russian Federation. The study shows that the absolute leaders in terms of infrastructure investments are such countries as China, the United States, and India. In the total amount of infrastructure investments, transport infrastructure and telecommunications have an absolute advantage. In recent years, one of the development priorities of the Russian regions has been investing in physical culture and sports infrastructure facilities. This is due to major international sporting events and increasing the investment attractiveness of the regions. An important trend in the development of infrastructural support for the development of regional economic systems has been the conclusion of international investment transactions (IIT) and regional agreements. Most countries and regions, leading in the inflow of foreign direct investment, are the leaders in terms of infrastructure development at the same time.
