探讨颠覆性创新是如何实施跨界行为，并分析外部环境对跨界过程的影响。基于颠覆性创新理论和创新扩散理论，以硬盘行业为对象，采用单案例研究方法，对硬盘行业的跨界活动进行数据编码与系统分析，构建跨界颠覆性创新的扩散全过程模型，以跨界为基调，包括搜索、涉入、扩散、颠覆4个阶段，各阶段之间联系紧密并受技术环境、市场环境、政策环境和竞争环境影响，形成跨界颠覆性创新的实现过程框架；同时总结得出跨界颠覆性创新的主要特征为爆发力和竞争力更强，以及过程管理比较复杂，需要跨界融合各方面资源和力量。

To explore how disruptive innovation implements cross-border behavior and analyze the impact of the external environment on the cross-border process. Based on the theory of disruptive innovation and innovation diffusion, we adopt a single-case study approach to coding data and systematically analyzing the cross-border activities in the hard disk industry, and construct a model of the whole process of diffusion of cross-border disruptive innovation, with cross-border as the keynote, including four stages of search, involvement, diffusion, and disruption, which are closely connected and influenced by the technological environment, market environment, policy environment, and competitive environment, forming a framework of the process of realizing cross-border disruptive innovation; at the same time, we conclude that the main characteristics of cross-border disruptive innovation are more explosive and competitive, as well as more complex process management, which requires cross-border integration of various resources and forces.
