[National Health Innovation System: relations between scientific fields and economic sectors].

Health Science and Technology is currently the subject matter of government and university actions. Such actions should converge to the establishment of a National Health Innovation System, which still calls for acknowledgment from the economic sector counterpart. A study was carried out with the purpose of describing the relations between scientific fields and economic sectors as a means of learning more about this System. Records from the Brazilian Directory of Research Groups (version 4.1) were examined and selected when Health was a keyword either to field of knowledge or economic sector. Data were compiled into multiresponse variables and analyzed in contingency tables using residual, correspondence, and cluster analyses. It was found that the Brazilian National Health Innovation System constitutes a sectorial system where competitiveness is more socially than economically-oriented, making this System favorably in tandem with the National Unified Health System as well as responsive to public policies focused on social welfare.
