我国科技评价政策主题演化研究

Research on the evolution of policy theme of science and technology evaluation in China

摘要:

本研究的目的是分析我国科技评价政策主题演化趋势，以进一步优化我国科技评价体系。本文共纳入114篇政策文件，将时间跨度划分为四个阶段，利用DTM模型挖掘政策主题的分布特征，引入基于距离的相似度指标（hellinger距离）分析主题演化趋势。研究结果表明，科技评价政策主题聚焦在9个方面。随着科技评价制度的完善，科技评价政策主题更加多元化。“科技监督与治理”、“人才评价”和“科技绩效评价”的主题强度呈现明显上升趋势，可能是未来科技评价工作中的重点内容。政策主题的演化方向和时代背景密切相关，呈现强延续性、强衍生性的特点。

Abstract:

This study aims to analyze the evolution trend of Chinese Science and Technology(S T) evaluation policy for optimizing Chinese S T evaluation system. A total of 114 policy documents were included in this paper, and the time span was divided into four stages. The Dynamic Topic Model was used to explore the distribution characteristics of policy topics, and the distance-based similarity index was introduced to analyze the evolution trend of topics. The results show that a total of 9 topics of S T evaluation policy are identified. With the improvement of the S T evaluation system, the policy topics of S T evaluation become more diversified. The topic intensity of "S T supervision and performance evaluation" and "S T governance and research ethics" shows an obvious rising trend, which may be the focus in the future. The evolution direction of the policy topic is closely related to the historical background, showing strong continuity and derivative characteristics.
