中国科技评价研究演进脉络与特征——建国70年来相关研究文本分析

以2 698篇中国科技评价研究相关文献作为分析样本，运用共词聚类分析法和社会网络分析法，构建不同研究阶段高频关键词谱系图和共词网络，探究不同研究阶段主题内容和变化趋势。总体而言，研究主题共性与差异并存；评价原则与导向发生了重大转折；评价主体较为单一；评价对象范围不断扩大，分类评价成为新趋势；评价方法日趋多样化；研究关联度和相互渗透性有所增强。在此基础之上，研究发现既有文献在科技评价主体、客体、指标体系构建、评价方法等层面尚存在一些局限性和空白。

Analysis on Evolution Logic and Characteristics of Science and Technology Evaluation in China

Based on 2 698 literature related to Science and Technology Evaluation, the research utilizes co-word cluster analysis and social network analysis aiming at establishing genealogy charts and co-word networks of high-frequency keywords in different research stages, exploring changes and tendency of research topics. Overall, similarities and differences lie in research topics; Big transition of evaluation principles and guidelines occurs; The evaluation subject remains single; The range of evaluation objects is expanding, and classified evaluation has become a new trend; Evaluation methods are diversifying; The correlation degree and mutual permeability are enhanced.On this basis, the research figures out that the existing literature still has some limitations and gaps in the aspects of science and technology evaluation subject, object, index system establishment and evaluation method.
