Based on the data of several domestic universities, 194 university capital input indexes are selected, including six categories: human input (students), human input (teachers), physical input, fund income, fund ex? penditure and other inputs. Through feature selection and feature extraction, with the help of three different data mining models, the paper gradually analyzes and sorts the impact of the above university capital investment indi? cators on the construction effect of the world-class universities with Chinese characteristics. It is found that the total amount of funding and research expenditure are of great importance to the construction of first-class univer? sities; the input of academic exchange reflects the mission of first-class universities and the needs of their capacity-building; the focus of human resources input is the structure and level of teachers and students. The core indicators of university capital investment reflect the social demands for universities in terms of highlighting construction benefits, improving scientific research capacity, and serving construction and development. It also puts forward some work enlightenment, such as making clear the practical construction path, improving the quality of personnel training and innovation ability, and constructing a reasonable educational environment.
