Abstract: The theory of disruptive innovation in national mega-projects is still lack of systematic understanding. This article will take China's high-speed railway project as an example to analyze the disruptive innovation pattern of national mega-projects. First of all, this paper systematically traces back to the theory of disruptive innovation and summarizes the connotations of disruptive innovations. Simultaneously, from the historical development of several typical national mega-projects in China, this paper summarizes the connotations of national mega-projects. Based on the two connotations, we summarize the theoretical basis of disruptive innovation in national mega-projects. Secondly, by analyzing the historical process of the development of China’s high-speed rail from the perspectives of technological innovation level-time dimension, market scale-time dimension and industry division dimension, we analyze the mechanism of the development of high-speed rail; by analyzing the mechanism of the implementation subject, the dominant factor and the key breakthroughs, we built the "Triple Three" pattern of disruptive innovation of China’s high-speed rail and analyze it from the perspectives of the innovation characteristics, scope of applications and innovation environments of disruptive innovation in national mega-projects. Finally, the conclusion is drawn and the research enlightenment of this article is analyzed from the perspectives of scope of applications of disruptive innovation in national mega-projects.

摘要： 国家重大工程的颠覆性创新理论目前仍缺乏系统性认识，本文将以中国高铁工程为例，分析国家重大工程的颠覆性创新模式。本文首先从前人对颠覆性创新相关理论的研究出发，进行系统性回溯并总结颠覆性创新的内涵；同时从中国几类典型国家重大工程的历史发展分析，总结国家重大工程的内涵；基于二者内涵的认识，构建国家重大工程颠覆性创新的理论基础。其次从技术创新水平-时间维度、市场规模-时间维度、产业分工维度分析中国高铁发展的历史进程；从实施主体、主导要素、关键爆发点的角度分析高铁发展要素的作用机理，构建中国高铁颠覆性创新的“三三三”模式，并从创新特点、适用范围、创新条件视角分析高铁模式；最后总结全文并从普适性角度分析本文的研究启示。
