Abstract: As a core equipment with strategic significance, the breakthrough in key core technologies of the “Pillars of a Great Power” is not only an important engine for enhancing China’s international status, but also a cornerstone for ensuring China’s scientific and technological security. With the risk of supply chain disruptions for critical core components posing a serious threat to the high-quality development of our economy and even national security, the urgency for breakthrough in key core technology of the “Pillars of a Great Power” is becoming increasingly pronounced. Current research on breakthrough in key core technologies of the “Pillars of a Great Power” primarily focuses on the process of achieving these breakthroughs and the differential roles of the main actor involved. In reality, technological breakthroughs are deeply rooted in their contextual systems, yet existing research has overlooked the unique context of breakthrough in key core technologies of the “Pillars of a Great Power”. To this end, by choosing to conduct a longitudinal exploratory single-case study on heavy-duty gas turbines, based on the phased context of breakthroughs in key core technologies of the “Pillars of a Great Power”, delineates the process of breakthrough in key core technologies within the evolution of the innovation ecosystem, thereby expanding the theoretical research on the key core technology of the “Pillars of a Great Power”.

摘要： 大国重器关键核心技术作为维护国家安全的重要支撑，其突破规律成为当前理论和实践亟需探索的问题。为此，基于创新生态系统理论视角，采用纵向探索式案例研究方法，以我国重型燃气轮机关键核心技术为案例研究对象，探究大国重器关键核心技术突破规律。研究结果表明：（1）大国重器关键核心技术突破依赖于创新生态系统适应性演进；（2）伴随着创新生态系统适应性演进，大国重器关键核心技术经历了逆向结构复制、正向构件突破、系统自主可控的突破过程；（3）大国重器关键核心技术突破遵循“情境-结构”的适应性匹配，创新生态系统演进态势需与技术突破情境相匹配才能实现关键核心技术突破。该研究揭示了大国重器关键核心技术突破机理，拓展了创新生态系统的理论应用，对我国突破技术封锁、实现科技自立自强具有重要启示意义。
