Abstract: The high concentration of assets and revenues of corporations or large enterprises on a national scale represents a risk that can hinder sustain­able development. For instance, in terms of a bank’s loan portfolio concentra­tion risk is so crucial that it is a separate significant type of risk in addition to credit risk. In the proposed article a corporate sector concentration index was constructed for countries for which revenue data of TOP-50 or TOP-100 larg­est enterprises is accessible from open sources. The index is based on the re­vealed pattern of decrease in the volume indicator of the company (revenue, assets) of the order of 1⁄n^z, where n is the serial number of the companies ranked in descending order of the indicator, and z is a country-specific pa­rameter. Based on all possibly available open statistics, providing data on 30 countries, the consistency of the statistical hypothesis about the dependence of the corporate sector concentration index on the Human Development In­dex and Ease of doing business is substantiated.
