本文基于国际合作论文数据检索与挖掘, 对纳米科技国际合作创新网络进行了系统分析, 描绘了合作网络的总体特征, 并利用基尼系数、核心边缘分布、中心性、聚类、数据可视化等方法分析了合作网络的结构和演进特征。研究发现, 中国在纳米国际科技合作网络中的地位愈加重要, 正成为美国之外的另一极;法国和南非在网络中发挥了桥梁和中介作用;越来越多国家意识到纳米科技的重要性, 着力通过国际合作推进本国纳米科技的发展。
Abstract
This paper conducts a systematic analysis on international collaborative innovation network of nano science and technology. The paper delineates the general characteristics of the collaborative network, and utilizes the methods like Gini coefficient, core-edge distribution, centrality, clustering, and data visualization to analyze its structure and evolution characteristics. The paper finds that the role of China becomes increasingly significant in the collaborative network. France and South Africa plays an intermediary role as a bridge in the network. More and more countries realize the importance of nano science and technology, and make their endeavor on promoting the development of their own country's nano science and technology through international collaboration.
