中国科技创新研究热点及演化的可视化分析

针对C N K I数据库中1998—2020年科技创新研究的2853篇文献,运用科学计量学方法,对中国科技创新的研究热点及演化开展研究.借助CiteSpace 5.7.R2可视化工具,绘制中国科技创新研究的知识图谱,主要包括关键词共现分析和突变分布、关键词聚类分析、关键词时间线分析和时区分析.研究表明,创新是引领发展的第一动力,中国始终坚持创新驱动发展,把科技创新摆在国家发展全局的核心位置,加快建设科技强国.但科技创新研究在不同时期的侧重点有所不同:2000—2006年,农业科技创新、高校科技创新、研究型大学、科技创新体系与机制等成为主流的研究热点;2006—2012年,科技创新体系、指标体系、知识产权、科技创新对策、技术创新、科技创新评价、科技创新能力、科技创新人才成为研究热点;2012—2020年,中国科技创新的研究热点主要集中在科技创新政策、创新驱动等方面.

Visual Analysis on the Research Focus and Evolution of Science & Technology Innovation in China

Based on 2 853 articles on scientific and technological innovation research in CNKI database from 1998 to 2020, the hot spots and evolution of scientific and technological innovation research in China is studied by using scientometrics method. With the help of CiteSpace 5.7.R2 visualization tool, the knowledge map of scientific and technological innovation research in China is drawn, which mainly includes keyword co-occurrence analysis and mutation distribution, keyword cluster analysis, keyword time line analysis and time zone analysis. Research result shows that innovation is the primary driving force for development. China has always been committed to innovation-driven development, placing scientific and technological innovation at the core of national development, and accelerating the building of a strong country in science and technology. However, the focus of scientific and technological innovation research in different periods is different: From 2000 to 2006, agricultural scientific and technological innovation, scientific and technological innovation in universities, research universities, and scientific and technological innovation systems and mechanisms have become mainstream research hotspots. From 2006 to 2012 research hotspots included, science and technology innovation system, index system, intellectual property, science and technology innovation countermeasures, science and technology innovation, science and technology innovation evaluation, science and technology innovation ability, science and technology innovation talents . From 2012 to 2020, the research hotspots of science and technology innovation in China mainly focus on science and technology innovation policy, innovation driving and so on.
