Against the backgroud ofincreasingly competitive market environment, disruptive innovation has become the key to obtaining a sustainable competitive advantage and determine the success or failure of enterprise competition. As an important part of the main body of innovation and development, 5G technology enterprises represented by Huawei and ZTE have important impacts on promoting the process of disruptive innovation. Although the number of 5G technology enterprises in China has been increased rapidly, the overall strength is still relatively weak, and has not yet had a systematic impact on the national and regional disruptive innovation process. Therefore, it is necessary to further explore the influencing factors of 5G technology enterprises ' disruptive innovation. What are the links between these factors ? Is it possible to further produce some combinations? What are the effects of these combinations on 5G technology enterprises to achieve disruptive innovation ? Thus, the black box of disruptive innovation evolution and operation can befuther opened.#br#There are still some limitations in the existing literature. From the perspective of research, the analytical framework of disruptive innovation is constructed on a single level, and the evolution path of disruptive innovation has not been effectively refined from specific cases. In terms of research content, there is little analysis on the influencing factors of the evolution and operation of disruptive innovation, and it is not clear what kind of connection exists between these influencing factors, and whether it can further produce a combination effect. In terms of research objects, there is a lack of large-scale science and technology enterprises, especially 5G science and technology enterprises, and thus it fails to effectively solve the practical problems that 5G science and technology faces in promoting the development of disruptive innovation. Therefore it is necessary to further deepen the research on the dynamic evolution and operation mechanism ofdisruptive enterprise innovation.#br#Facing the" 14th Five-Year Plan " and the "long-term goal of 2035", this paper puts forward the TOE theoretical framework based on the case data of 30 5G technology enterprises, adopts the two-step fsQCA to construct the configuration effect model of 5G technology enterprises' disruptive innovation between nine influencing factors at three levels of technology, organization and environment, and analyzes the evolution path of 5G technology enterprises' disruptive innovation, which is of great significance to the development of disruptive innovation theory.#br#It is found that industry competition pressure is a remote factor for 5G technology enterprises' disruptive innovation. The government financial support and local economic development have not yet been able to provide essential support for 5G technology enterprises ' disruptive innovation capability. At the same time, there are three evolution paths to enhance the disruptive innovation capability of 5G technology enterprises, including the driving of "independent innovation of technology", orientation of "open innovation of market"and progress of "collaborative innovation of mechanism". By comparing the three evolution paths, it is found that theindependent innovation of technology-driven path is more suitable for the development and change of Chinese market, and can meet the needs of enterprise disruptive innovation capability construction.#br#This study proposes the TOE theoretical framework to study the evolution path of 5G technology enterprises to achieve disruptive innovation, which is more typical and targeted to explore multiple evolution conditions and other issues, and provides theoretical reference and enlightenment for the development of relevant technology enterprises. At the same time, this study adopts the two-step fsQCA, and combined with the Chinese context variables of government finance, local economy and industry competition and their enabling effects on disruptive innovation, it explores the path suitable for the improvement of disruptive innovation performance of Chinese technological enterprises, providing a possible method that is more in line with the practice of Chinese context ,and expanding the innovation characteristic theory and practical research system of technology enterprises in the Chinese context.#br#
