“Technology lock-in” has become an important reason hindering the dynamic upgrade of China’s manufacturing global value chain. Technology lock-in generally goes through five stages: marketization, systemization, application, institutionalization, and socialization. Among them, marketization is a key link in the formation of technology lock-in and system lock-in. Since traditional fuel vehicle technology has been locked in the fossil fuel-based energy system, the application range of new energy has been restricted. Therefore, getting rid of the lock-in of traditional fuel vehicle technology is the key to the leap-forward development of the new energy vehicle industry, not just the technological innovation of new energy vehicles. From the perspective of the automobile manufacturing industry, this article analyzes the locking factors and formation mechanisms that affect traditional fuel vehicle technology and new energy vehicle technology and uses and expands the Arthur model. Based on Matlab simulation, it better presents the impact of fuel vehicles. The locked-in relationship of automotive technology.
