摘　　要：[目的/意义]在扩大国际科技交流与合作,推进“双一流”学科建设的背景下,分析材料科学领域国家科研合作网络特征,为学科对外合作发展提供参考借鉴。[方法/过程]选取2018-2022年材料学科ESI高被引论文,采用文献计量、社会网络法从国际发文表现力、国家合作网络中心度、网络密度、k-核凝聚子群、国家-机构-主题关系等方面分析材料科学领域高被引论文的国家主体网络特点。[结果/结论]材料科学领域高水平科研合作比例较高的国家有澳大利亚、德国、英国、加拿大等;美国、澳大利亚、新加坡、德国、英国等国合作论文质量较高;科研合作国家数量逐年增加,国家合作主体网络不断壮大;网络已具有规模并出现核心-边缘国家子群,但整体网络密度还有提升空间,国家之间合作交流有待加强。[Objective/Significance] In the context of expanding international exchanges and cooperation in science and technology and promoting the construction of "double first-class" disciplines,the characteristics of national scientific research cooperation network in the field of materials are analyzed to provide reference for the development of international cooperation of disciplines.[Method/Process] The ESI highly-cited papers in materials science during 2018-2022 were selected,and the national subject network characteristics of highlycited papers in materials science were analyzed from the perspectives of international publication performance,national cooperative network centrality,network density,K-kernel cohesive subgroup,state-institution-topic relationship,and so on by using bibliometric and social network methods.[Results/Conclusions] The results show that countries with a high proportion of high-level scientific research cooperation in the field of materials include Australia,Germany,Britain,Canada,etc.The quality of cooperative papers from the United States,Australia,Singapore,Germany,the United Kingdom and other countries is higher;The number of countries cooperating in scientific research is increasing year by year,and the network of national cooperative entities is growing.The network has a scale and core-periphery country subgroups have appeared,but the overall network density still has room to increase,and the cooperation between countries needs to be strengthened.
