This study focuses on the optimization paths of university informatization project management under the background of digital campus. By analyzing the key problems and challenges such as poor management systems and mechanisms, insufficient depth of technology application, and resource integration dilemmas, and based on the whole-life cycle management theory and the mixed management concept of "rigid framework and flexible execution", a systematic four-dimensional improvement path framework of "system integration - intelligent drive - flexible management - security governance" is proposed. Research shows that the management foundation is reconstructed through system integration and data governance, process reengineering is driven by intelligent technology, and the unification of standardization and flexibility in project management is realized relying on improved management mechanisms. Meanwhile, a solid implementation support system is constructed from three dimensions: organization, system and technology, providing multi-faceted support for the digital transformation of project management. The research results provide theoretical and practical support for the reform of the digital governance paradigm of university informatization projects, and have important reference value for promoting universities to achieve high-quality digital transformation.
