：从资源角度来看，智库是一个拥有大量知识资源的知识库。知识经济时代，知识层面成为继载体层面后的知识资源管理与计量的新视角，知识元概念的提出为实现知识资源直接管理和计量提供了可能。中文文本的分类、挖掘、标引等研究基础为我国智库成果的知识元抽取提供了技术保障，将抽取出的知识元归类、进一步归纳出对应的描述规则有利于实现知识层面的中文智库成果管理与评价。文章基于构建主题词表进行文本抽取的方法，选择中国国际问题研究中心2015年全部可获得的智库研究成果为样本，进行成果知识元的抽取，经过人工选择、精炼抽取结果后归纳总结出中文智库成果的知识元类型及对应描述规则。共归纳出事实知识元、定义知识元、结论知识元、方法知识元和关系知识元等5种知识元类型和16种具体的描述规则。

From the perspective of resources, the think tanks are large knowledge base with rich knowledge resources. In the era of knowledge-driven economy, the knowledge resources management and measurement focus more on knowledge level than the carrier level. Knowledge elements are the key role when dealing with knowledge itself. Research on the classification, mining and index of Chinese text provides the technological support for knowledge element extraction of Chinese think-tank products. The descriptive rules, induced from the classification of extracted knowledge elements, would benefit the management and assessment of Chinese think-tank products from level of knowledge. According to the method of building thesaurus for text extraction, the paper chooses the accessible think-tank research products from China Institute of International Studies in 2015 as samples. The types and descriptive rules of Chinese think-tank products are summarized after man-made selection and purification of extraction results. Five kinds of knowledge elements such as fact knowledge element, definition knowledge element, conclusion knowledge element, method knowledge element and relation knowledge element as well as 16 types of descriptive rules of Chinese think-tank products are summed up.
