Dynamic typology of investment activity of oil companies

Oil and gas are the most important gains for the russian economy. So the improvement of these industries is very important and should be analyzed very well. In this paper we analyze the tendency in the development of these industries for the past ten years. We use a factor-analysis for the identification of determinants which have positive and negative effects on the development of the performance of these companies. Some of these determinants are the investment activities or the influence by the government. As result we get three types of firms related to their performances. There are the leaders, the middle and the outsiders.
