[Purpose/Significance] In recent years, China has been committed to building a strong educational country. As key academic institutions within universities, university libraries play a vital role in disseminating knowledge, nurturing talent, and supporting scholary research. Their development is of great significance in promoting the high-quality development of higher education and realizing the goal of building a strong educational country. This study focuses on the "15th Five-Year Plan" of university libraries. It analyzes the development characteristics of university libraries during the "14th Five-Year Plan" period, explores the opportunities and challenges they face in the new era, and puts forward key points and suggestions for the "15th Five-Year Plan" to promote the transformation and upgrading of university libraries and better support the building of a strong education country. The innovation of this article is that it comprehensively considers various factors and national strategic requirements, and puts forward a relatively systematic and forward-looking development plan for university libraries, which provides a new perspective and practical guidance for the research and practice of university libraries in the new era. It contributes to the improvement of the theoretical research system of library science and promotes the deep integration of library services with teaching, scientific research, and cultural heritage in the digital age. [Method/Process] This study mainly adopts the methods of literature review, data analysis, and case study. By collecting and analyzing a large body of literature on library development policies, strategic plans, and related research findings from home and abroad, it examines the development context and trends of university libraries. At the same time, it analyzes the statistical data of library funds, resource construction, and service development during the "14th Five-Year Plan" period to objectively understand the current situation and problems. In addition, it also studies the development cases and practices of some excellent university libraries at home and abroad to draw on successful experiences. The theoretical basis of this study is drawn from the theory of library science, information science, and the relevant theories of education and cultural development. The empirical basis is mainly based on the actual situation and data of the university libraries in China in the past few years. [Results/Conclusions] During the "14th Five-Year Plan" period, university libraries have not only made certain achievements in smart library construction, digital transformation, and information literacy education, but they also face challenges such as reduced funding and polarized academic evaluation services. In the "15th Five-Year Plan" period, university libraries should seize the opportunities provided by national strategies such as national cultural digitization and educational strength, and focus on eight aspects, including to modernize the management system, strengthen the construction of data infrastructure, promote the construction of digital special collections, support digital intelligence teaching, explore the management and operation of future learning centers, build intelligent service systems supported by artificial intelligence, provide full-cycle support for scientific research, and enhance the reader's experience in the virtual environment. At the same time, it is necessary to pay attention to the evaluation of development results, summarize experience and lessons learned, and continuously optimize the development path. Future research can further explore the specific implementation strategies and detailed operation methods of each plan point, strengthen the cooperation and integration between libraries and other departments in the school, and conduct in-depth research on the application and impact of emerging technologies in libraries.
