基于973计划项目资助的科研合作网络演变分析

Analysis on Evolution of Scientific Cooperation Network Based on Funding of 973 Projects

利用973计划项目资助的论文数据,绘制组织间科研合作网络可视化图谱,分析973计划项目资助的科研合作网络演变。研究结果表明:基于973计划项目的科研合作网络整体上趋于聚集和连通,小世界特征逐渐显现;随着科研合作网络的成熟,以985高校为中心、大陆研究机构和非985高校为副中心的结构形态趋于稳定;基于973计划项目的科研合作网络演化具有明显的学科特征,科研合作网络呈现出由综合交叉、农业、人口和健康领域为主转变为以重要前沿学科、材料和信息领域为主的发展趋势。

Using the statistics of the publication papers supported by 973 project＇s funding, this article visualizes the inter-organizational scientific cooperation network and investigates the evolution of scientific cooperation net- work subsidized by 973 projects. The results indicate that scientific cooperation network tends to be more central and connective, and it seems to be a ＇Small World＇ network gradually. With the evolution of scientific research co- operation network, the 985 universities play the dominant role, while China mainland research institutions and oth- er mainland universities play the secondary role over time. The evolution of scientific cooperation network based on 973 projects shows significant discipline characteristics. The scientific cooperation network are changing from the core subjects mainly composed of intersecting discipline, agriculture, population and health into those mainly composed of important scientific frontiers, materials and information.
