国家自然科学基金联合基金发展态势与科研合作分析
Analysis on Development Trend and Scientific Research Cooperation of NSFC

从科技论文角度对国家自然科学基金联合基金资助项目的绩效进行实证研究，主要采用文献计量法和知识图谱方法，从年份、学科、著者等角度进行计量分析，从机构合作和关键词共现进行科学知识图谱分析。旨在为揭示该基金的科研产出现状，科研管理部门改进科研管理、提高基金使用效益和资助质量提供数据参考和依据，今后申请国家自然科学基金联合基金提供研究方向。结果表明：论文产出是快速增长，在计算机领域研究成果最多，基金论文大多以著者合作形式，围绕中国科学院大学的机构合作网络，建立了以数值模拟、页岩、力学性能为热点主题的关键词聚类。
From the perspective of scientific papers, this paper makes an empirical study on the performance of the projects funded by the National Natural Science Foundation of China (NSFC). It mainly adopts bibliometric method and knowledge mapping method to conduct quantitative analysis from the perspectives of years, disciplines and authors, and makes scientific knowledge mapping analysis from the perspective of institutional cooperation and keyword co-occurrence. The purpose of this paper is to provide data reference and basis for revealing the scientific research output status of the fund, improving the scientific research management, improving the use efficiency and funding quality of the fund, and providing research direction for applying for the National Natural Science Foundation joint fund in the future. The results show that: the output of papers is growing rapidly, with the most research achievements in the computer field. Most of the funded papers are in the form of author cooperation. Around the institutional cooperation network of the University of Chi-nese Academy of Sciences, key words clusters with hot topics of numerical simulation, shale and mechanical properties are established.
