Abstract By using methods of stratified sampling and purposeful sampling, this paper extracted 176 distinguished professors in Changjiang Scholars Program in science, engineering, agriculture and medicine disciplines as samples to compare their SCI papers published before and after their election. Four indicators used are the annual mean number of SCI papers, annual mean citation times of per SCI paper, Category Normalized Citation Impact and Journal Normalized Citation Impact. This research illustrates that, first, influences of distinguished professors′ SCI papers before and after their election are both higher than the world′s average level, but there is still a gap with the world′s top level. Second, the number of SCI papers published after their election shows a significant increase compared with the number before their election, but the quality is relatively stable. Third, from the perspective of disciplines, the numbers of SCI papers in four categories have increased significantly; the quality of SCI papers in science has decreased significantly, while the quality of SCI papers in engineering, agriculture and medicine has increased, but not significantly. Therefore, universities should adopt classification evaluation, reduce the requirement on the quantity of scientific research achievements in basic disciplines, and introduce a representative work system into quality assessment indicators; establish earlywarning and supervision mechanism of research quality to properly handle the relationship between the quality and quantity of research output; increase investment, and improve quality standards of research achievements of applied discipline talents in the evaluation of professional titles and assessment of the term of employment.
