[Purpose/significance] Scholars are the main body of interdisciplinary research. The measurement of schol⁃ ar’s interdisciplinary is an important part of interdisciplinary research and an effective support for talent management and technological innovation. Because of the shortcomings of the existing research on the interdisciplinary measure⁃ ment of scholars from the aspects of scholars′ publications and citations, this paper proposes to measure scholars' inter⁃ disciplinary collaboration from a new perspective. [Method/process] Based on cross-language alignment of authors and integration of Chinese and English research, scholars' disciplines are identified according to China's discipline cat⁃ alogs and departmental setting system, and the interdisciplinary collaboration network of scholars are constructed. This paper proposes three diversity indicators of scholars' interdisciplinary collaboration: variety, balance, and disparity, and two cohesion indicators of scholars' interdisciplinary collaboration: intensity and density. Taking Renmin Universi⁃ ty of China as a case, after connecting the Chinese and English information of the authors, the interdisciplinary collabo⁃ ration network of scholars in Renmin University of China is constructed to measure the scholars’interdisciplinarity. [Result/conclusion] The results show that this indicator system can effectively measure scholars’interdisciplinary col⁃ laboration. The measurement indicator system proposed in this paper is an effective supplement to interdisciplinary measurement research. It has certain application value for understanding the characteristics of scholars’interdisciplin⁃ ary collaboration and provides a scientific reference for the development of disciplinary development and the manage⁃ ment of interdisciplinary collaboration.
