Knowledge networks in Brazil's health sciences.

This study aims to analyze the network of interactions of Brazilian medical research groups, identifying key actors and their roles in generating and diffusing knowledge. Social network analysis was applied, with data from the Research Groups Directory Census of the National Council of Scientific and Technological Development, from 2016. The main results show (1) the central role of universities, public institutes, and university hospital research groups; (2) the importance of scientific infrastructure and research capability of scientists in knowledge production; (3) the minor role of the industry, denoting the fragility of university–industry interactions; (4) spatial concentration of network actors, mostly located in the south and southeast of Brazil; and (5) a great opportunity to expand flows and cooperation. Regarding these results, the recent budgetary cuts in science and technology resources since 2016 seem to be a misguided and detrimental strategy as these resources are essential for future technological and industrial development.
