By means of text mining techniques such as python and Gephi, this paper makes an in-depth exploration of the subject words related to academic and scientific research in double first-class policy documents. It is found that double first-class policy demands academic and scientific research in five aspects:academic organization construction, academic evaluation mechanism, academic frontier and innovation, interdisciplinary and industry-university-research, and international academic cooperation. Then, based on the cognition of university teachers on these five aspects, it is proposed to strengthen the cognition of university teachers on double first-class and academic influence, to construct academic organizations based on "discipline" and give full play to the academic role of academic organizations, and to strengthen international cooperation and enhance international academic reputation.
