Disruptive technological innovation has important strategic significance for China's strategic emerging enterprises to break through foreign technological blockades and achieve independent control of key technologies. It is precisely through the evolution and development of a series of disruptive technological innovations that China's new energy vehicle enterprises have achieved a profound transformation in key technologies and market patterns. Therefore, it is of significance to clarify the internal mechanism of disruptive technological innovation in China's new energy vehicle enterprises, which can provide reference for the innovation and development of strategic emerging enterprises.#br#Disruptive technological innovation is endowed with strong exploration, a long research and development cycle, and high risk. The relevant technological and market changes evolve through the interaction of technological iteration innovation and market segmentation diffusion. Therefore, revealing the evolutionary laws of disruptive technological innovation in China's new energy vehicle enterprises from both technological and market perspectives is the underlying logic for exploring its realization mechanism. However, the existing research on the realization mechanism of disruptive technological innovation of China's new energy vehicle enterprises is mostly based on the guiding role of macro-policies and the synergistic effect of middle-level industries, and insufficient attention is paid to the innovative main role of new energy vehicle enterprises; the evolutionary laws of disruptive technological innovation in technology iteration and market diffusion in China's new energy vehicle enterprises are not clear, and the dynamics and complexity of disruptive technological innovation in enterprises are in need of deconstruction; moreover, the interaction between resource-focused actions and dynamic capabilities and their mechanism of action on disruptive technological innovation are in the vague.#br#Therefore, this study aims to answer the following questions: (1) What are the laws of the occurrence and evolution of disruptive technological innovation in China's new energy vehicle enterprises? (2) How do enterprises conduct resource-focused actions and build dynamic capabilities at different stages of development? (3) How does the interaction effect of resource-focused actions and dynamic capabilities affect the disruptive technological innovation of China's new energy vehicle enterprises?#br#To address the issues, the paper selects 5 typical cases of China's new energy vehicle enterprises for longitudinal exploratory research, and forms 87 000 words of cross-verification data through diversified data collection methods. It firstly identifies the key milestone events of three enterprises for stage division. Then it extracts 3 core categories, 9 main categories and 27 subcategories from 392 pieces of evidence through open coding, axial coding and selective coding, and further constructs the process model of disruptive technological innovation of China's new energy vehicle enterprises in combination with stage markers. Thirdly, the study conducts a theoretical saturation test on the process model using the remaining two enterprises. On the basis of the process model, the paper constructs a realization mechanism model of disruptive technological innovation in new energy vehicle enterprises in order to explore the interaction effects between resource-focused actions and dynamic capabilities on the realization and evolution of disruptive technological innovation.#br#The study finds that (1) the disruptive technological innovation of new energy vehicle enterprises presents three characteristics: continuous enrichment of technological innovation methods, continuous iteration of technological life cycle, and sequential realization of niche market development, medium and high-end market penetration and high-end market introduction; (2) enterprises have gradually realized the combination, capability and leverage of resources through the resource-focused actions of resource bricolage-resource choreography-resource orchestration, while the dynamic capabilities have experienced the evolution process of externally oriented environmental perception, internally driven learning and innovation, and internal and external collaborative integration and expansion capabilities, realizing the upgrading from the first-order ability to adapt to the environment to the second-order ability to create new capabilities; (3) as the key factors for the realization and evolution of disruptive technological innovation, the interaction between resource-focused actions and dynamic capabilities of enterprises has experienced a three-stage transition from factor aggregation to knowledge innovation to system symbiosis, and they have respectively played foundation, promotion and leading roles in the emergence, development and upgrading of disruptive technological innovation. The research conclusions provide strategic support for promoting China's new energy vehicle enterprises to carry out organized disruptive technological innovation activities.#br#
