Identification of structures of large economic systems using rating methods

To test the toolkit, an aggregated analysis of the sectoral structures of the Russian and world economies are carried out according to the reporting data of the largest companies (according to Forbes ratings). The representation of companies in the largest category characterizes the structure of the international division of labour. The obtained partial structures of the world and Russian economies are compared, and conclusions and recommendations are made. The research results can be in demand in the creation and improvement of decision support systems for large companies, as well as priorities and government programs for the development of national and regional economies.
