Abstract: It is of great practical significance for the latecomers to accelerate the technology progress and realize the technology catch-up by identifying the key elements of technology change and the influence on the transformation of innovation ability. Based on the theoretical hypothesis that the leading elements determine the innovation ability and then affect the innovation performance, this paper constructed the theoretical model of the evolutionary relationship among the innovation element, innovation ability sequence and innovation performance. And then, taken the innovation activities of BYD's traditional fuel cars and new energy vehicles, and the changes of the technology trajectory as the study case, abstracted the innovation elements and innovation capability sequence which could promote the technology progress and finally achieve technology leap in different innovation stages, and constructed the theoretical model among mainstream and new stream innovation elements, innovation capability sequence and innovation performance evolution. Finally, from the perspective of characteristic innovation elements, transformation of collaborative innovation model and transformation of innovation ability, the dynamic mechanism of promoting technology leapfrogging from mainstream to new stream was expounded. This research has reference significance for enterprises to optimize the combination of innovation elements so as to achieve technology catch-up.

摘要： 识别企业技术变迁的关键影响要素及对企业创新能力转化的影响，对于后发企业加快技术进步，实现技术赶超具有重要的现实意义。文章基于企业创新主导要素决定创新能力序列，进而影响创新绩效的理论假设，构建企业创新要素、创新能力序列及创新绩效间演化关系的理论模型；在此基础上以比亚迪传统燃油车和新能源汽车的创新活动及其技术轨道变迁作为研究案例，提炼企业在不同创新阶段促进技术进步并最终实现技术跨越的创新要素组合和能力序列，构建二元创新要素组合、创新能力序列和创新绩效演化的理论模型；最后，从特征性创新要素驱动、协同创新模式转化驱动和创新能力转化驱动等角度阐述促进主新流技术跨越的动力机制。本研究对于企业优化创新要素组合和创新能力序列，最终实现技术赶超具有借鉴意义。
