安世半导体事件发酵一个月，车企和供应链怎么说？

Core Viewpoint - The automotive industry is facing renewed supply chain challenges, particularly concerning the semiconductor company Nexperia, which has become a focal point in recent quarterly reports due to its significant market share and the ongoing control disputes affecting its operations [2][3]. Group 1: Nexperia's Market Position - Nexperia, previously part of NXP Semiconductors, has a dominant position in the automotive basic chip market, holding approximately 20% of the global market share in small-signal discrete semiconductors [3]. - The company is actively expanding into emerging SiC power devices and providing specific products like analog interface chips, which amplifies the risk of supply chain disruptions [3]. Group 2: Recent Regulatory Developments - On September 29, the U.S. Department of Commerce proposed a "50% ownership penetration rule" to expand the scope of its entity list [4]. - The Dutch government imposed restrictions on Nexperia's asset and business adjustments, leading to a suspension of the parent company, Wingtech Technology's control over Nexperia [4]. - On October 4, the Chinese Ministry of Commerce issued export control notifications prohibiting Nexperia China and its distributors from exporting specific components manufactured in China [4]. Group 3: Impact on Automotive Production - By the end of October, Honda's factory in Mexico halted operations due to chip shortages, while Nissan announced production cuts at its domestic plants starting November 10 [4]. - Volkswagen and Bosch reported partial production stoppages, with Volkswagen assessing alternative procurement solutions to mitigate supply chain impacts [4]. - The delivery cycle for automotive-grade products has extended to over 12 weeks, with companies actively seeking alternative products [5]. Group 4: Supply Chain Management Improvements - The automotive industry has learned from past supply chain disruptions, enhancing inventory levels and supplier management practices [12][18]. - Companies are establishing secondary safety stock for critical chips and improving direct communication with semiconductor suppliers [17]. - Despite improvements, challenges remain due to the complexity of semiconductor manufacturing and the unpredictability of supply chain issues [18].
