A quantitative model of Russia's information and communication technologies (ICT) ecosystem has been proposed that describes the main relationships between its participants, as well as the impact of environmental factors on the functioning of the ICT ecosystem. Based on the model, we have assessed the longterm (until 2030) potential for the development of Russia's ICT sector in the case of the state's active and stimulating strategy and the formation of an advanced system of institutions. We have also evaluated the contribution of the ICT sector to the macroeconomic dynamics while implementing the target scenario.
