Abstract: What is the disruptive innovation model of integrated circuit industry under the background of digital technology?Systematic research of existing theories are still blank.To make up for the gap,based on the theory of disruptive innovation,systematically integrate the literature of digital technology,the theory of industrial technology track and the theory of business model innovation,through the exploratory case study of Obit and Lexin.Firstly,define the concept of disruptive innovation of integrated circuit industry under the background of digital technology,and then bring about three research achievements as follows:①explain the internal mechanism of "spiral isomorphic rise" matching between digital technology innovation track and integrated circuit industry technology track,propose"double track matching structure";②reveal the "spiral iterative ascent" mechanism of business model innovation, propose "value closed cycle system";③clarify the action mechanism between "double track matching structure" and "value closed cycle system",construct "spiral isomorphism iterative ascent" of China's integrated circuit industry disruptive innovation model under the background of digital technology.

摘要： 数字技术背景下集成电路产业颠覆性创新模式是什么？现有理论鲜有系统性研究。为弥补空白，基于颠覆性创新理论并有机整合数字技术文献、产业技术轨道理论、商业模式创新理论，对欧比特与乐鑫两企业运用探索性多案例法，首先界定数字技术背景集成电路产业颠覆性创新概念，然后形成3项研究成果：①阐释数字技术创新轨迹与产业技术轨道“螺旋同构上升”机制，提出“双轨匹配结构”；②揭示商业模式创新“螺旋迭代上升”机制，提出“价值闭合循环系统”；③明晰“双轨匹配结构”与“价值闭合循环系统”作用机制，构建数字技术背景我国集成电路产业“双螺旋同构迭代上升”颠覆创新模式。
