Abstract: The research of technological trajectory has long been the leading topic in the field of technological innovation. However, it still lacks an overall discussion on the relationship between the transition of industrial technology trajectory and the evolution of technological innovation. Based on the needs of strategic transition and the construction of industry safety in China, this article expounds the formation and evolution mechanism of industrial technology trajectory. Then the paper introduces the theory of level transition to explain the evolutionary regularity of technology trajectory, and further reveals the motives, types and trigger conditions of technical track transitions. Above these, the paper puts forward the level transition process model of industrial technology trajectory’s evolution, and hopes to make a new attempt to characterize the development of industrial technology innovation.

摘要： 技术轨道理论研究对技术创新领域有着多年的认识与实践，但就技术轨道的跃迁与技术创新的演化发展二者之间仍缺乏全面系统的探讨。从当前国家战略转型和产业安全建设的现实需要出发，围绕产业技术轨道的形成演化机理，引入能级跃迁理论用于阐释产业技术轨道的演化规律，并进一步揭示技术轨道跃迁的基本动因、主要类型及触发条件，构建产业技术轨道演化的能级跃迁过程模型，提出一种对产业技术创新演化发展进行合理表征的新尝试。
