[目的/意义] 通过调研国内外新一代机构知识库的研究现状和服务需求，分析关键技术和功能特点，提出发展趋势，为建设新一代机构知识库发展提供建议。[方法/过程] 通过文献研究对机构知识库技术和功能发展趋势进行总结，并根据相关研究成果，分析新一代机构知识库的11个关键技术、标准和协议。最后通过研究和实践经验提出新一代机构知识库在框架、功能、服务目标等方面的发展趋势。[结果/结论] 新一代机构知识库发展趋势包括：从机构学术仓储到机构信息基础设施；从自存档到自动提交；从独立平台到与科研管理系统融合与发展；从学术成果管理平台到学术资源服务中心；从学术成果数据检索到大数据语义研究支持；从成果存档到新型学术交流社区；从应用计量指标到建立全新学术评价体系。
[Purpose/significance] By investigating the research status and service demand of the new generation knowledge at home and abroad, this paper analyzes the key technologies and functional characteristics of the next generation repositories. It puts forward the key trends of institutional repositories, and provides some suggestions for the development of next generation repositories.[Method/process] Through literature research, this paper summarized the development trend of institutional repository technology and function. Then, it introduced 11 key technologies, standards and protocols of the new generation repositories. By researching and designing the functions, it analyzed the development of next generation repositories in many aspects such as framework, functions and service target.[Result/conclusion] The paper generalizes the development trends of next generation repositories as followings:①from institutional repository to institutional information infrastructure.②from self-archiving to automated submission or ingestion.③ from independent platforms to current research information system(CRIS).④ from scholarly outputs management platform to academic resources service center. ⑤from information retrieval to supporting big data and semantic retrieval. ⑥from academic archives to academic scholarly communities. ⑦from providing metrics and altmetrics services to creating a new system of academic evaluation.
