：文章研究了我国当前“双一流”建设学科的分布格局与合作态势，认为“双一流”建设中应当规避过度竞争，强调合作与差异化特色。研究以“双一流”建设学科和高校及其科研论文为对象，对高校“双一流”建设学科共现网络、共“双一流”建设学科的合作结构等方面进行分析。结果发现：76%的“双一流”建设学科高校间科研合作强度低于全国平均值，主要“双一流”建设学科之间的合作并不活跃；只有天文学、地质资源与地质工程、农林经济管理等相对小众的“双一流”建设学科之间合作良好；我国“双一流”建设中亟待规避重复建设，应在合作的基础上形成互补之整体，共同迈向世界一流。

This paper studies the distribution pattern and collaboration situation of current "Double First-class" disciplines in China and finds that current "Double First-class" construction in China should avoid excessive competition, and emphasize collaboration and differentiation. The research takes the disciplines and universities listed in "Double First-class" construction as data and analyzes the co-occurrence network of "Double First-class" disciplines in universities and the collaboration structure of co-occurrence "Double First-class" disciplines. The study found that 76% of the research collaboration strength between university-pairs which have co-occurrence "Double First-class" disciplines are lower than the national average, showing that the collaboration between main "Double First-class" disciplines in China is not active. Relatively minority "Double First-class" disciplines, such as astronomy, geological resources and geological engineering, and agricultural and forestry economic management, have good collaboration. In general, in the development of "Double First-class" in China, it is urgent to avoid excessive competition among the same discipline units.
