The construction of national first - class undergraduate majors embodies the aspirations for developing top - notch under? graduate education, majors, and talents. Its layout is deeply rooted in the long - term planning for China’s first - class undergraduate education. Therefore, this study attempts to conduct a statistical analysis of the basic situation and a cluster analysis of the spatial lay? out based on the collected data of 11,502 national first - class undergraduate major construction sites, in order to clarify the geograph? ical distribution and allocation of these construction sites across the country. The results reveal that the layout of national first - class undergraduate major construction sites exhibits the characteristics of “three imbalances” and “three possessions”: imbalances in geo? graphical distribution, inter - school distribution, and disciplinary distribution, as well as possessing key regional concentrations, dis? tinct strategic orientations, and dynamic adjustment mechanisms. In light of these findings, this study will propose targeted and specific practical strategies, aiming to provide guidance for the comprehensive implementation of the objectives and requirements of the “Double Ten Thousand Plan” at national - level first - class undergraduate program construction sites.
