创新驱动下我国R&D研究演化及热点主题分析

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。

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

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.
