基于合著论文数据,运用文献计量和社会网络分析方法系统分析了2000-2014年期间干细胞研究领域国家间科研合作网络的结构与演化特征,对比了干细胞研究论文高产国家的国际合作模式与研究影响力.研究发现,干细胞研究领域国际科研合作规模不断扩大,一张高度连通世界各国的科研合作网络已基本形成;高产国家集中于北美、欧洲和东亚,美国、英国、德国和法国长期处于网络的中心位置;中国的干细胞研究论文高速增长,网络地位不断提升;美国与欧洲论文高产国家组成了密切的多边合作群体,亚洲论文高产国家的国际合作以与美国合作为主;欧美论文高产国家的研究影响力高于亚洲高产国家,中国干细胞研究的整体水平还与其他高产国家有较大差距.
Based on the data of co-authored papers, the author systematically analyzed the structure and evolution characteristics of research cooperation networks between countries in the field of stem cell research during the period of 2000-2014 by using bibliometrics and social network analysis methods, and compared the international cooperation models and research effects of high-yielding countries with stem cell research papers The study found that the scale of international scientific cooperation in the field of stem cell research has been continuously expanded, and a scientific research cooperation network highly interconnected with other countries in the world has been basically formed. The high-yielding countries are concentrated in North America, Europe and East Asia, the United States, Britain, Germany and France The center of China’s high-speed growth of stem cell research papers, network status continues to improve; the United States and the European papers high-yielding countries formed a close multilateral cooperation groups, high-yielding countries in Asia and the United States to cooperate mainly in international cooperation; The impact is higher than that of Asian high-yielding countries, and the overall level of Chinese stem cell research still lags behind that of other high-yielding countries.
