Abstract: The management system governing research institutions at Double First-Class Universities serves as a breakthrough in the institutional reform of universities' scientific and technological innovation. Institutional evaluation research, which identifies institutional strengths and deficiencies and proposes improvement pathways, bears practical significance for universities to boost the efficiency of organized research. Integrating the inherent logic of text mining and the PMC Index Model, this study constructs an evaluation framework for the management system of research institutions at Double First-Class Universities. By adopting the policy consistency index alongside visualization tools, a quantitative evaluation is conducted on 12 selected representative institutional documents. The results reveal prominent deficiencies awaiting improvement covering five dimensions: institutional applicable subjects, institutional design, institutional publicity, institutional objectives of institutional operation, and institutional partners of research activities. Accordingly, targeted suggestions for institutional optimization are put forward from the perspectives of classified administration, continuous institutional revision, and multi-stakeholder negotiation.
