[目的/意义]在科技全球化的背景下,科研合作模式也趋向多元化的发展,其模式的演变与科研产出的创新度之间是否存在以及存在怎样的关系值得探讨。[方法/过程]本研究以中国海洋大学2009~2018 ESI农业科学的合作论文为研究对象,通过社交网络分析方法以及颠覆性指数表征的创新度量化方法,在十年的时间维度上分析总结其在合作模式与创新程度方面的普遍发展规律以及二者之间的关系。[结果/结论]① 合作网络中合作中心的点度中心度增长会对科研成果创新度产生负面影响;② 合作网络中合作中心的接近中心度和中介中心度的增长在不同合作网络规模下,分别对科研成果创新度产生负面影响和正面影响。[创新/价值]以机构为中心,在时间维度上挖掘单一学科合作模式演变与科研产出创新度之间的关系,挖掘推动学科发展的潜在因素,为学科建设和创新发展提供建议。[Purpose/Significance] Under the background of science and technology of globalization, evolution of science research cooperation tends to be increasingly diversified. It is worth exploring whether there is and what kind of relationship between evolution of science research cooperation mode and innovation of scientific research output. [Design/Methodology] Based on 2009~2018 ESI agricultural science collaborative papers of Ocean University of China, this study analyzed and summarized the general development law of cooperation mode and innovation degree and the relationship between them in the time dimension of 10-year through social network analysis and innovation degree quantification method represented by disruption index. [Findings/Conclusion] ① The increasing degree centrality of the cooperative center in the cooperative network will have a negative impact on the innovation degree of scientific research;② The increasing freeman closeness and betweenness of the cooperative center in the cooperative network will hav
