摘要
以1996-2004年间国际纳米科技合作的SCIE数据为例,利用社会网络理论中的连续核心-边缘模型描绘国际科技合作网络。基于核心度,划分合作网络中的核心国家和边缘国家,并量化各国在国际合作网络中的相对位置变化。另外,分别利用MDS分析和因子分析揭示核心国家与边缘国家的合作信息,比较两种方法的差异。认为该分析框架对核心-边缘结构分析具有普遍意义,对纳米科技的实证分析也具有现实意义。
This paper analyzes the international scientific collaboration network (1996-2004) by the continuous core-periphery model of social network analysis. Taking SCIE data of international collaboration on nanotech research area. from 1996 to 2004 as an example, the paper divides the countries and areas in network into core sets or periphery sets and quantifies their position changes in different years. The paper also reveals the information of relationship between core countries (areas) and periphery countries (areas) with the tool of MDS analysis and factor analysis, and then it compares the difference of these two methods, The authors point out that the analysis not only provides the framework for core-periphery analysis, but also pictures the international collaboration network of nanotech research area.
