Résumé
The output of ESI-covered scientific papers in BRICs from 2014-01-01 to 2014-06-30 and its impact were analyzed according to the relative publication index ( RPI) and relative citation impact ( RCI) , and the world relative position of scientific research output in BRICs was analyzed by constructing a two-dimensional analysis framework according to the subject specialization index and standard citation impact index, which showed that the absolute output of scientific papers in BRICs was rather high, the distribution of relative scientific research output was not proportional between different subjects, the relative scientific research output in many subjects was signifi-cantly lower than that in the world, the RCI index of 22 subjects in BRICs was lower than that in the world. The specialization degree of subjects was lower in China, Brazil and India than in Russia, the standard RCI index in BRICs was significantly lower than that in the world, indicating that the academic level of scientific papers in BRICs was lower than that in the world. Certain suggestions were put forward for working out the scientific develop-ment policies and adjusting the subject structure in China.
