基于CiteSpace的聚羟基烷酸酯研究科研合作网络可视化分析

Visualization and Analysis of Polyhydroxyalkanoate Research Scientific Collaboration Network Based on CiteSpace

为探究全球聚羟基烷酸酯(PHA)研究的学者科研合作紧密度、时空特征和未来趋势,基于文献计量可视化分析软件CiteSpace,以Web of Science(WoS)数据库为数据源,对2013—2022年收录的论文进行学者科研合作的归纳分析。研究结果表明:2013—2022年聚羟基烷酸酯研究的科研合作紧密度较小,全球范围的合作较为松散,合作关系存在明显的个人、机构和地缘指向特征,合作关系表现出“强强合作”的特征,并且合作机构以高校为主,其中实力雄厚的研究机构发文量相对也较高;发文量最多的国家依次是中国、印度、美国、意大利和西班牙,其中美国的发文量虽高,但研究者人数较少,成果基本集中于部分高产研究者。今后,研究者不仅要注重地区之间的合作,还应注意学科之间的合作,跨地域、跨学科可以增加研究驱动力。

In order to study the scientific research intensity,spatiotemporal characteristics and future trends of global polyhydroxyalkanoate(PHA)research,based on the bibliometric visual analysis software CiteSpace,the Web of Science(WoS)database was used as the data source to summarize and analyze the research cooperation of scholars from 2013 to 2022.The results show that from 2013 to 2022,the degree of scientific research cooperation of polyhydroxyalkanoate research is relatively low,the global cooperation is relatively loose,and the cooperative relationship has obvious individual,institutional and geographical orientation,while the cooperative relationship shows the characteristics of“cooperation between powerful institutions”,and the cooperative institutions are mainly universities,among which the number of strong research institutions is relatively high.The countries with the largest number of publications are China,India,the United States,Italy and Spain.Although the number of publications in the United States is high,the number of researchers is small,and the results are basically concentrated in some high-yield researchers.In the future,researchers should not only pay attention to inter-regional cooperation,but also pay attention to interdisciplinary cooperation,which can increase the driving force of research across regions and disciplines.
