基于跨学科研究是科研生产力发展的重要情境，探讨了国家层面对跨学科研究的支持、跨学科研究管理体制、运行机制、评价机制、跨学科组织及其与产业界的联系对研究型大学跨学科科研生产力提升的影响及作用机制，通过203份问卷样本的回归分析，对研究假设进行检验。结果表明，国家层面对跨学科研究的支持对研究型大学跨学科科研生产力提升没有显著影响，健全的跨学科研究管理体制、运行机制、评价机制、合理的跨学科组织及其与产业界的联系对研究型大学跨学科科研生产力提升有着显著、非常显著或极显著的正向影响；跨学科研究评价机制对研究型大学跨学科科研生产力提升的影响作用最大，次之是跨学科研究管理体制、跨学科研究运行机制、跨学科组织与产业界的联系，而跨学科组织对研究型大学跨学科科研生产力提升的影响作用最小。

Based on the important situation that interdisciplinary research can promote the development of research productivity, the paper analyses the effects of the national support of interdisciplinary research, the interdisciplinary research management system, operation mechanism and evaluation mechanism, the interdisciplinary research organizations and the contact between the interdisciplinary research organizations and the industry on the promotion of interdisciplinary research productivity in research universities as well as the underlying mechanism. The hypotheses are tested through the regression analysis of 203 questionnaire samples. The results indicate that there is no significant effect of the national support of interdisciplinary research on the promotion of interdisciplinary research productivity in research universities, there are significant, very significant or extremely significant and positive effects of other elements on the promotion of interdisciplinary research productivity in research universities. The interdisciplinary research evaluation mechanism has the greatest effect on the promotion of interdisciplinary research productivity in research universities, followed by the interdisciplinary research management system, the interdisciplinary research operation mechanism, the contact between the interdisciplinary research organizations and the industry, and the reasonable interdisciplinary research organizations.
