Data services,knowledge services,and information services are the core service elements of university libraries in the context of the Double First-Class Initiative.Combined with the current situation of insufficient overall service capacity of libraries,this paper proposed strategies and implementation paths for optimizing the service system from three aspects:the construction of the professional qualification system for librarians,the establishment of post institutions,and the construction of library culture.Long-term path:putting library human resource management into the legal track,taking the lead in local legislation,and promoting the construction of library legislation and professional qualification certification system;optimizing the personnel system,implementing hierarchical management and classified assessment for professional librarians and auxiliary librarians.Short-term path:intensive post allocation,namely,assigning the core strength in the core post,and tackling the temporary major work combining multiple forces in the form of a"working group";building an open knowledge service ecosystem,accelerate the cross-border integration of libraries and other organizations,and striving to build the core competitiveness of libraries. 展开更多

With the advancement of the“Double First-Class”initiative,universities are increasingly focusing on attracting top-tier talent to enhance faculty quality and strengthen academic disciplines.The blind competition for high-end talent among universities reflects an overshadowing of academic values by economic considerations,neglecting the growth patterns of top talent and the development laws of higher education.This study investigates and reflects on the real-world challenges of faculty mobility in universities,aiming to provide effective guidance for managing university faculty teams. 展开更多

Purpose:This critical policy analysis aims to comprehensively examine the second round of China's first-class discipline development project,commonly known as the Double First-Class Initiative(DFC Initiative or Shuang Yiliu Jianshe).Design/Approach/Methods:We conducted desk research between May 2022 and December 2023 using relevant policy documents,academic literature,news sources,and commentaries that specifically focused on the second round of the DFC Initiative in China.Employing a critical policy analysis approach,we analyzed the gathered data from three key perspectives:policy as text,policy as discourse,and policy effects(including both first-and second-order effects).Findings:The second round of the DFC Initiative was implemented within the context of strengthened state regulation,prevalent managerialism,and an emphasis on promoting education equality in China's higher education development.A notable shift in structural dynamics occurred between the first and second round.These include the possibility of universities being added to or removed from the official list,increased academic autonomy for selected universities,and the promotion of interdisciplinary research within specific institutions.The implementation of the second round of the DFC Initiative reflects China's commitment to developing an internationalization strategy with Chinese characteristics.This strategy aims to align with China's national strategic needs and position the country as a cooperative partner,promoter,competitor,and potential leader in global scholarship.Originality/Value:By employing a critical policy analysis approach,this study offers a comprehensive examination of the second round of the DFC Initiative in China,contributing to existing knowledge on the development of world-class university policies in the country. 展开更多
