[Purpose/significance] The virtual academic community has become an emerging platform for scholars to carry out scientific research cooperation. The comparative study of scholars' research cooperation in virtual academic communities represented by academic blogs and academic journals is helpful to clarify the importance of virtual academic communities in scientific research cooperation, and it will promote the integration of emerging academic exchange platforms and traditional academic exchange platforms. [Method/process] Taking the field of information science as an example, 640 bloggers in the field of information science in sciencenet blog up to March 22, 2019 were selected as research objects, and 16 core scholars among the bloggers in science net were identified. Based on the comparative data of academic journals in CSSCI from 2014 to 2018, this paper analyzes the relationship between core scholars' scientific research cooperation in science blogs and academic journals, and explores the interdisciplinary cooperation
between scholars in science blogs and academic journals. [Result/conclusion] Research shows that scholars' research cooperation in academic blogs cannot be significantly transformed into scientific research cooperation in academic journals. Scholars' interdisciplinary cooperation based on academic blogs is more common and extensive than interdisciplinary cooperation based on academic journals.
