创新驱动下我国R&D研究演化及热点主题分析

The Evolution and Hot Topics Analysis of R&D Research in China under the Innovation-Driven Strategy

无论是创新驱动战略实施还是科技创新能力提升都离不开R&D,通过R&D研究演化发现热点主题,可为后续研究提供参考借鉴。通过对我国1998-2018年以R&D为主题的文献进行梳理,借助文献计量学方法,运用信息可视化分析工具,对文献的关键词共现密度、关键词共现聚类和突变词等信息进行可视化图谱分析,研究R&D文献演化过程及热点主题。研究发现,20年来我国以R&D为主题的文献研究沿着"宏观面—微观面—宏观面"演化推进,并且政府补贴、融资约束、战略性新兴产业及创新效率与R&D的关系分析成为当前研究热点。

Whether it is the implementation of innovation-driven strategy or the improvement of scientific and technological innovation capacity, R&D cannot be ignored. After researching evolution of R&D subject, we found the hot topics that will provide reference for follow-up research. We collected and reviewed papers were published during the period from 1998 to 2018 in the Chinese academic journals about R&D subject. Based on bibliometrics methods, we used the information visualization analysis tools to analyze the information about keywords co-occurrence density, keywords co-occurrence clustering and mutation words. Then we got the evolution process and hot topics. We found that the research with R&D subject has been promoted along the evolution of "macro-micro-macro" in the past 20 years. Nowadays, there are four hot topics related to R&D subject: government subsidies, financing constraints, strategic emerging industries, and innovation efficiency.
