The article is focused on the activity of the global business services companies in Moscow and the patterns of their embeddedness in the local economy. The research findings indicate: the growing role of Moscow as a focus of global corporate networks and strong links between foreign and national capital; three basic strategies of involvement in the Russian economy, specific for certain sectors of business services; a much stronger gateway function of Moscow for professional services than for the financial sector; the continuing central role of Russia at the national scale and partly at the supranational scale (within the post-Soviet space), where it is challenged by some national capitals and the complete loss of central position within eastern Europe.
