Abstract: [Purpose/Significance] In the current era, integrated and coordinated development is the main trend of social development. University libraries need to explore how the Internet has changed the way people think and promote regional coordinated development to actively explore the integrated development model in a wider range, optimize the efficient allocation of resources in the internal and external integrated development, promote the coordinated development of industries, stimulate innovation capacity, promote the emergence of new models and new formats, and realize the superposition effect of resources and service aggregation and multiplication effects, improve social competitiveness, and promote their sustainable development. [Method/Process] The high-quality development of university libraries requires not only the integration and promotion of certain subject content, but also a comprehensive integration plan and development strategy that takes into account both internal and external factors. University libraries take "cultivating virtue and nurturing people" as the foundation, and improve their resource allocation, management platforms, and service levels through the internal integration construction of development concepts, digital technology, and composite resources. Based on the service of talent cultivation, teaching reform, and discipline construction in universities, university libraries are simultaneously integrating external services with publishers, bookstores, and their cities, seeking a mutually beneficial cooperative development model through the vertical integration of the cultural industry upstream, midstream, and downstream. In the development of multi-collaborative integration, they need to explore the construction of a diversified development system, establish a multi-domain cooperation mechanism, enhance service capabilities, innovate development ideas, and gradually achieve sustainable development goals from consolidating joint forces to stimulating vitality. [Results/Conclusions] Diversified and integrated development is an inevitable trend in the development of the times. In recent years, in the construction and service upgrading of smart libraries, university libraries have achieved certain results in the integration and development of digital academic platform services, new learning ecology construction, virtual real interaction space construction, intelligent service management, and other aspects. However, university libraries have low participation in the integration of extended services with publishers, bookstores, and their cities, and lack a systematic approach in terms of scientific planning and their high-level design has not yet yielded significant social benefits. Overall, there is still a lot of room for innovation and improvement in resource, service and platform integration in university libraries. It is necessary to keep up with the times, seize development opportunities, build an open development system, seek collaborative models of integration and mutual benefits, integrate quality and effectiveness, and achieve innovative transformation and development.
