Based on the SCI papers, each of which areauthored by at least one Chinese scholar and published in the journals of six key areas, e.g.Medicine-Research&Experimental, this study did the research on the international collaboration articles and non-international collaboration articlesrespectively, built the indicators for measuring the extent of inter-disciplines, assessed the extent of the effect of international collaboration on interdisciplinary research, and compared the extent of inter-disciplines of the articles authored by Chinese scholars with the average extent of the global articles. The main findings are: (a)international collaboration has promoted researches of inter-disciplines assuredly; (b) the extent to which international collaboration promotes research of inter-disciplines is influenced by research fields, and the extent of burgeoning and applied research fieldsare higher; (c) the extent of interdisciplinary research on international collaborative papers are getting higher and higher; and (d) the levels of interdisciplinary research in multiple fields of China are lower than international averaged ones.
