Vietnam's 2045 development plan requires thorough reforms in science and technology, which underlines the role of research-oriented universities in generating and transforming knowledge. Understanding the current research performance and productivity in Vietnam is important for exploiting future agendas.
This study aims to explore the growth patterns and collaborations in the scientific publications of Vietnam.
Data on documents in the Web of Science Core Collection database were searched and extracted to examine the research performance in Vietnam. Publication growth patterns in both quantity and quality were examined. The evolution of research disciplines and collaboration networks were also analyzed. Trends in the growth in the number of publications, citations, and average citations per publication between 1966 and 2020 were presented. Temporal tendencies of the 10 most productive research areas in each period were illustrated. VOSviewer software was used to analyze the discipline network, country network, and institution networks. The trends and the geographical distribution of the number of publications and citations were analyzed.
A total of 62,752 documents in 8354 different sources from 1966 to 2020 were retrieved. A substantial growth was observed in the Vietnamese scientific output during this period, which was mainly research with international collaboration. Natural sciences such as mathematics, materials science, and physics were the top 3 most productive research fields during 1966-2020 in Vietnam, followed by experimental research fields such as multidisciplinary sciences, plant sciences, public, environmental, and occupational health. In 1966-2020, there was the emergence of multidisciplinary research-oriented universities in both public and private sectors along with a significant increase in the number of interdisciplinary and multidisciplinary publications. Although the scientific quality has improved, these publications are still of mostly medium quality as they are concentrated in middle-ranking journals.
Our study highlights the notable growth in research performance in terms of both quality and quantity in Vietnam from 1966 to 2020. Building multidisciplinary and interdisciplinary research agenda, developing networks of local and international researchers for addressing specific local issues, improving the participation of private sectors, and developing science and technology mechanisms are critical for boosting the research productivity in Vietnam.
越南的2045年发展计划要求在科学技术方面进行全面改革，这凸显了研究型大学在知识创造和转化中的作用。了解越南当前的研究表现和生产力对于推进未来议程至关重要。
本研究旨在探索越南科学出版物的增长模式与合作情况。
检索并提取科学网核心合集数据库中的文献数据，以考察越南的研究表现。对出版物数量和质量方面的增长模式进行了研究。还分析了研究学科的演变和合作网络。呈现了1966年至2020年间出版物数量、引用次数及每篇出版物平均引用次数的增长趋势。阐述了各时期10个产出最多的研究领域的时间趋势。使用VOSviewer软件分析学科网络、国家网络和机构网络。分析了出版物数量和引用次数的趋势及地理分布。
检索到1966年至2020年来自8354个不同来源的62752篇文献。在此期间，越南的科学产出有显著增长，主要是国际合作研究。数学、材料科学和物理学等自然科学是1966 - 2020年期间越南产出最多的前3个研究领域，其次是多学科科学、植物科学、公共、环境和职业健康等实验研究领域。1966 - 2020年，公立和私立部门都出现了以多学科研究为导向的大学，跨学科和多学科出版物数量显著增加。尽管科学质量有所提高，但这些出版物大多仍为中等质量，因为它们集中在排名中等的期刊上。
我们的研究突出了1966年至2020年越南在研究表现方面在质量和数量上的显著增长。建立多学科和跨学科研究议程、发展本地和国际研究人员网络以解决特定的本地问题、提高私营部门的参与度以及发展科学技术机制对于提高越南的研究生产力至关重要。
