摘　　要：本研究在领域主题粒度上探究学科交叉对科学突破的影响,推进对科学突破动力机制的认知。通过分析时序数据动态变化特征,揭示新兴研究主题的突破性潜力及其学科交叉特征。首先从新兴研究主题中识别科学突破主题,之后分析不同类别中科学突破主题的学科交叉特征,进而分析科学突破主题及其知识基础文献的被引量与学科交叉数量增减演进趋势的一致性,最后测度科学突破主题的被引量与其学科交叉数量时间序列之间的预测因果关系,以此探究科学突破的产生与学科交叉的关联。以干细胞领域为例开展实证研究发现,科学突破主题的学科交叉特征可划为三个类别,且科学突破主题与其知识基础在被引量和学科交叉数量的增减演进趋势上存在较高的一致性,大多科学突破主题被引量时间序列与学科交叉数量时间序列间的预测因果关系并不显著,因此不能仅用学科交叉数量指标识别或预判科学突破主题。本研究为更好地理解科学突破研究的特征提供了有用的线索与有益的启示。The paper explores the impact of interdisciplinary collaboration on scientific breakthroughs at the granularity of research topics,advancing our understanding of the driving mechanisms behind scientific breakthroughs.By analyzing the dynamic characteristics of temporal data,it unveils the breakthrough potential of emerging research topics and their interdisciplinary features.Specifically this paper initially identifies scientific breakthrough topics based on emerging research topics and examines their interdisciplinary characteristics.Furthermore,the consistency in the increase and decrease evolutionary trends in the number of citations and the number of cross-disciplinary documents on scientific breakthrough topics and their knowledge base documents is analyzed.Finally,it measures the predictive causal relationship between the citation count of scientific breakthrough topics and their interdisciplinary quantity time series,thus investigating the association between the emergence of scientific breakthroughs and interdisciplinarity.Using stem cells research as a case study,this empirical research categorizes the interdisciplinary characteristics of scientific breakthrough topics into three categories.Results show that there is a great consistency between the scientific breakthrough topics and the knowledge base in the increase and decrease evolutionary trends in the number of citations and interdisciplinary quantity.However,the predictive causal relationship between the citation time series of most scientific breakthrough topics and the time series of interdisciplinary is not significant.Therefore,relying solely on the interdisciplinary quantity metric may not effectively identify or predict scientific breakthrough topics.The paper provides valuable insights to better understand the characteristics of scientific breakthrough research.
