In the global economy and in the context of globalization, corporate governance has established itself as a reliable and key factor in the formation of the investment attractiveness of integrated structures, with the help of which it is possible to build up competitive advantages and obtain more affordable, relatively inexpensive, stable and long-term sources of investment. It has long been common practice for foreign investors to establish business contacts with Russian companies to assess the degree of development of corporate governance as responsibly as, for example, the financial and economic results of their activities. And this is natural, because, as a rule, it is no secret to anyone that an improperly built or involved corporate governance mechanism reduces the market value of companies by 30-35%. In the course of our study, we came to the conclusion that in most Russian companies the importance of the formation of investment attractiveness as an essential factor is still underestimated. As a result, most corporate procedures in these integrated structures are formal and declarative in their nature, which gives only some temporary improvement. An analysis of special foreign literature on the issue under study shows that it is impossible to simply transfer foreign standards and corporate governance mechanisms to Russian companies due to many national and industry specifics. It is clear that, in the conditions of Russian realities, this situation requires creative refinement and addition of global corporate governance standards, taking into account national and industry specifics, and also the development of a simulation financial and economic model, which should allow optimizing the solution of strategic tasks of increasing their investment attractiveness, identifying the most significant environmental factors and develop methodological approaches to improve it.
