Abstract: Analysis based on Science Citation Database can reflect scientific papers output and academic influence of a scientific research institution. Based on data from ESI (2000-2010), this paper evaluates the output of high-level scientific papers of Beijing University of Aeronautics and Astronautics(BUAA), and makes comparisons between BUAA and other "985 Project universities" by factor analysis. The results demonstrate that the number of BUAA's scientific papers has risen steadily, but the citation influence of the papers is still weak. Engineering science, materials science and physics are BUAA's preponderant disciplines, while other disciplines are relatively weak. On the whole, BUAA is at a medium to lower position in "985 Project universities".
