高校作为国家创新体系中的重要主体，在跨学科研究中发挥着日益重要的作用。由于跨学科研究具有不确定性高、成果影响力释放等待时间较长等特征，如何有效构建鼓励跨学科产出支撑体系成为了亟待解决的问题。本文从探索影响跨学科研究的内外部因素出发，通过对1147份问卷数据的多元线性回归，分析主体的经验特质、相关学科特征等内部因素，和制度环境支撑、研究平台实力等外部因素分别对学科交叉研究产出的数量、质量、标志性成果及效率的影响，并基于研究结果对平台建设、制度保障以及研究者培养提出启示建议。

As an important actor in the national innovation system, universities are playing an increasingly important role in interdisciplinary research. Since interdisciplinary research is characterized by high uncertainty and time-costly for the build the research impact, how to effectively launch a support system to encourage interdisciplinary output has become an urgent problem to be solved. Starting from the exploration of internal and external factors that affect interdisciplinary research, this article analyzes the influence of internal factors such as the subject's experience characteristics and relevant discipline characteristics, and external factors such as institutional environment support and research platform strength on the quantity, quality, landmark achievements and efficiency of interdisciplinary research output based on 1147 questionnaire data. From the empirical results, suggestions are put forward for platform construction, institutional protection and researchers training for universities.
