重大科技基础设施（简称重大设施）是具有前沿性、创新性、规模性及影响力的科学研究系统，在国家科技创新体系中占据重要地位。为了深刻认识重大设施的战略价值、充分发挥设施科研潜力、支撑未来设施的统筹布局，需要深入研究其对学科领域发展的影响作用。以专用型重大设施中的对撞机为研究对象，分析其论文成果的引文分布及主题强度演化，研究了重大设施对学科领域发展的影响过程，定义了不同影响类型，并形成了判别不同类型的三维战略坐标。在对比中、日、欧三方对撞机的成果产出和影响情况后，提出了相关政策建议。

Large research infrastructures (LRIs) are the most cutting-edge, innovative, large-scale and influential research system, which plays an increasingly important role in national technological innovation system and development strategy. In order to have a deep understanding of the role of LRIs in scientific development, give full play to the research potential of the facilities, support the overall layout of future facilities, in-depth study of its impact on the developments of subject areas is required. Taking collider as research object, put forward the impact mechanism of LRIs on the development of subject areas. By combining the evolution processes of citation distributions and topic intensities of literature, define the three-dimensional strategy diagram to distinguish different impact types. Analyzing the output and impacts of colliders from China, Japan and Europe comparatively, then proposing several policy recommendations.
