Abstract: Interdisciplinarity is a complex and multidimensional concept, so it is difficult to fully describe its’ essential characteristics by a single indicator. Most previous studies have analyzed interdisciplinarity from single dimension, lacking an overall and systematic perspective. In this paper, we decompose, and then integrate the external knowledge integration, internal knowledge convergence and research activity patterns of interdisciplinarity from three different dimensions. Based on publication data of the winners of Derek de Solla Price, a comparative analysis of category integration, knowledge convergence and scientific cooperation are conducted, to explore the differences, adaptability, relations and possible combination of the three different measurement methods. Compared with the single indicator, our measurement from three dimensions can better profile the interdisciplinary characteristics of research object. Such a comprehensive dimension also provides a new perspective of evaluating interdisciplinary research.

摘要： 跨学科是一个复杂、多维的概念，单一的测度方法无法全面描述其本质特征。先前的研究大多针对跨学科某一维度进行分析，缺乏整体视角和系统建构。本研究对跨学科的外部知识融合、内在知识会聚与科学合作模式三个不同维度进行有效分解与整合，分别从参考文献学科多样性、目标文献学科多样性和合作机构学科多样性三个维度进行测度和综合比较分析，以普赖斯奖获得者的研究论文为例，探索不同测度方法的共性与差异、适应性与结合点，以及跨学科研究不同维度之间的内在关联。与单一维度的方法相比，三维测度可以更加全面地剖析研究对象的跨学科特征，同时也为跨学科的测度研究提供了新思路。
