There are some problems in the practice of collaborative protection of intangible cultural heritage in underdeveloped areas, such as deviated value orientation, complex contradictions and conflicts, imperfect security mechanism, faint awareness of performance and so on. In view of these problems, from the perspective of local university library, this paper discusses the path for the main body of intangible cultural heritage protection to participate in the construction of regional collaborative protection mechanism of intangible cultural heritage, and puts forward strategies for local university library to participate in the construction of value orientation mechanism, collaborative operation mechanism, collaborative guarantee system and collaborative performance evaluation system as the main organizer by giving full play to its role and advantages in publicity and education, leading demonstration, human resources and practical experience.
