The rising demand for new energy vehicles (NEVs) and the intensifying industry competition have spurred the continuous development of the new energy vehicle parts (NEVPs) industry, and have also raised new demands for enterprise supply chain risk management. This study employs a combination of internal interviews and empirical research to conduct a comprehensive assessment, measurement, and impact analysis of the supply chain risks faced by NEVPs enterprises in China, thereby revealing the key factors influencing the supply chain risks of NEVPs enterprises. The research findings indicate that risk factors closely associated with external order risks, such as natural disasters in export countries, political risks, macroeconomic conditions, and exchange rate policies, are all significant elements in the risk management of the NEVPs supply chain. Moreover, industry cycle risks, such as policy adjustments targeting the NEVs industry, also exert a considerable influence on the supply chain risks of NEVPs. The study underscores the importance of sustainable management of the NEVPs supply chain and provides a robust theoretical basis for the research system of supply chain risk management in the NEVs industry.
