Inward investments as the cornerstone of the entry mode choice are still considered a frontier issue within the field of internationalization – as judged from the academic interest as well as from the numerous articles published in scientific journals. Despite considerable progress in later years in formulation of theories, many weaknesses still exist within this field. A further development of theory is therefore needed. Nowadays emerging markets show the greatest activity in the field of internationalization, e.g the Russian market, which is considered by most potential entrants as a huge opportunity. The methods of entry and models of operations of international contractors in the Russian market, based on the investment decisions, are investigated in this paper.
