以中国引文数据库(CCD)为数据源,采用数理统计、社会网络分析等方法,从知识输入的视角对35年来国内跨学科知识交流网络的结构特征进行了分析。结果发现,跨学科知识交流网络具有小世界性质,但无标度特征不显著,属SED网络;学科间的跨学科知识交流总体上较为频繁和畅通,但存在非均衡性特点;环境科学与资源利用、计算机软件及计算机应用、生物学等13个学科在网络中的地位较为突出且稳固,学科间相互联系与作用形成了10个跨学科知识交流群落。
Using the Chinese citation database (CCD) as the data source, this paper analyzes the structural features of the interdisciplinary knowledge exchange network in China in the past 35 years from the perspective of knowledge input using mathematical statistics and social network analysis. The results show that the interdisciplinary knowledge exchange network is of a small-world nature, but the scale-free features are not significant and belongs to the SED network. The interdisciplinary interdisciplinary knowledge exchange is generally more frequent and unblocked, but has the characteristics of non-equilibrium. The environment science and resources Thirteen disciplines such as computer science, computer science, computer science, biology, etc. have become prominent and stable in the network. Interdisciplinary interdisciplinary research has formed 10 interdisciplinary knowledge exchange communities.
