摘要: [目的/意义] 探讨不同关键时间点对新兴研究主题影响力的不同表征。[方法/过程] 首先,综述当前拐点时间的应用场景及获取方法,并根据知识扩散中网络节点增长机制与特征构建新兴研究主题在创新演化路径上的拐点识别方法。其次,对比分析首次出现时间、平均时间和拐点时间的差异,探讨新兴研究主题产生影响力的最早时间点。最后,以干细胞研究主题为实证领域,分析不同关键时间点对新兴研究主题影响力的不同表征能力。[结果/结论] 拐点时间可以比平均值时间提前识别有影响力的主题。首次出现时间、平均时间和拐点时间在主题发展路径中意义区别显著,新兴研究主题在创新路径中分布时间的确定需要综合3种不同类型的关键时间点。

Abstract: [Purpose/significance] To explore the different representations of the impact of different key time points on emerging research topics.[Method/process] Firstly, we summarized the application scenarios and acquisition methods of the current turning point time, and constructed the turning point identification method of emerging research topics on the innovation evolution path according to the growth mechanism and characteristics of network nodes in the knowledge diffusion. After that, the differences between "first appearance time" "average time" and "inflection point time" are compared and analysed, and explored the earliest point in time when emerging research topics have an impact. Finally, taking stem cell research topics as an empirical field, we analysed the different representational capabilities of different key time points on the influence of emerging research topics.[Result/conclusion] The turning point time can identify influential topics earlier than the "average time". "First appearance time" "average time" and "inflection point time" have significant differences in the topic evolution path. The determination of the distribution time of emerging research topics in the innovation path requires the synthesis of three different types of key time points.

Key words: evolutionary path, innovation path, inflection point, emerging research topic, curve fitting
