How Mainland China becomes new center of gravity for automotive semiconductors

The global automotive semiconductor industry is experiencing a geographic realignment, with mainland China at the center of that shift. The country’s combination of vehicle-production scale, rapid electrification, advanced driver assistance systems (ADAS) and the transition toward software-defined vehicles (SDVs) is driving semiconductor demand at a pace unmatched by other major automotive markets.

Mobility Global forecasts automotive semiconductor revenue associated with vehicles produced in mainland China to increase from about $13 billion in 2020 to approximately $60 billion by 2031. More important than vehicle volume alone, however, is the increasing semiconductor value of each vehicle. Since 2023, mainland China has begun to pull ahead of Europe, North America and Japan/South Korea in semiconductor content per vehicle as Chinese automakers accelerate the deployment of battery-electric powertrains, Level 2+ driving systems, intelligent cockpits, centralized computing and zonal electrical/electronic (E/E) architectures. (See chart, below.)

Electrification, autonomy and SDVs reshape demand for automotive semiconductors

Three technology transitions are supporting mainland China's growing demand for automotive chips.

Electrification

Battery-electric and plug-in hybrid electric vehicles require significantly more semiconductor content than conventional internal combustion engine (ICE) vehicles, particularly in power electronics, battery-management systems and high-voltage control. Mainland China's scale in electrified vehicle production therefore creates a substantial underlying source of semiconductor demand.

Intelligent driving

Advanced ADAS has rapidly shifted from a premium feature to a mass-market differentiator in mainland China. Volume manufacturers are increasingly deploying Level 2+ and above systems across lower-priced models, increasing demand for cameras, radar, high-performance processors and memory. Moving from Level 2 to Level 2+ can significantly increase semiconductor value as sensor counts and computing requirements rise.

Transition to SDVs and centralized or zonal E/E architectures

Mainland Chinese electric vehicle manufacturers, including Li Auto, Nio and Xpeng, have been among the fastest to introduce centralized computing architectures. This transition replaces numerous distributed electronic control units with more powerful central and zonal controllers, increasing demand for high-performance system-on-chips (SoCs), networking devices and memory.

Together, these trends are creating a powerful multiplier effect. Mainland China not only produces vehicles at scale but is also adopting semiconductor-intensive technologies faster than most other automotive markets.

A large automotive semiconductor market still dependent on foreign supply

Conversely, mainland China's strength as a semiconductor consumer contrasts sharply with its position as a supplier.

Mainland China accounted for approximately 45% of global automotive chip consumption in 2025, while mainland China-headquartered suppliers accounted for only about 11% to 12% of global automotive semiconductor supply. (See chart, below.) This gap leaves the Chinese automotive semiconductor supply chain dependent on international companies, particularly in advanced compute and other higher-performance categories.

Automotive semiconductor supplier global market shares by region (2025):

That gap, however, is beginning to narrow as domestic suppliers expand their presence in the automotive chip market.

Domestic suppliers have made particularly strong progress in power semiconductors, silicon carbide (SiC), microcontrollers and selected cockpit and ADAS processors. Companies such as Black Sesame Technologies, BYD Semiconductor, Horizon Robotics, SemiDrive Technology and StarPower Semiconductor are expanding their automotive presence, while SMIC and other domestic companies are increasing semiconductor manufacturing capacity.

Nevertheless, localization remains uneven. Mature-node and power semiconductor applications are substantially easier to localize than cutting-edge automotive compute. High-end SoCs, central computing devices and some safety-critical components continue to depend heavily on international automotive technology and manufacturing capabilities.

Chinese automakers are taking a larger role in automotive semiconductor development

Perhaps the more significant structural change is happening at the automaker level.

Mainland Chinese original equipment manufacturers are moving beyond the conventional role of semiconductor buyers. They are investing in chipmakers, collaborating directly on semiconductor development and, in some cases, designing their own processors.

Li Auto, Nio and Xpeng have developed proprietary AI or autonomous-driving processors. BYD is pursuing a similar direction with its Xuanji A3 processor, intended for advanced driving applications. At the same time, Geely's ecosystem has supported SiEngine Technology, while several major automakers have invested in Horizon Robotics.

The strategic logic extends beyond import substitution. Custom silicon allows automakers to optimize processors around proprietary AI models, potentially reduce hardware costs, integrate hardware and software more tightly and secure greater control over technology roadmaps and supply.

This development could reshape the traditional automotive electronics value chain. As OEMs take greater responsibility for architecture, software and semiconductor validation, established tier 1 suppliers may shift from providing complete proprietary electronic systems toward integration, manufacturing and engineering roles.

How localization is influencing semiconductor sourcing strategies and product development ecosystems

Government policy is accelerating this transition through investment, standards and industry coordination. Mainland China's semiconductor strategy increasingly connects automotive chip standardization with domestic validation and procurement initiatives, helping local semiconductor companies shorten qualification cycles and obtain vehicle design wins.

Yet, localization does not necessarily mean the exclusion of international suppliers.

Foreign semiconductor companies continue to occupy critical positions in mainland China's automotive market. At the same time, they face growing pressure to become more deeply embedded in the domestic semiconductor industry through local manufacturing, partnerships and product development. Infineon Technologies, for example, has expanded cooperation with mainland Chinese manufacturing partners as part of its localization strategy. Similarly, Volkswagen's software business has partnered with Horizon Robotics through Carizon to develop automated-driving technologies suited to the mainland Chinese market.

These developments point toward a more nuanced outcome than simple semiconductor decoupling. A parallel ecosystem is emerging in which domestic and international companies compete for the same vehicle programs, but increasingly within mainland China's local automotive semiconductor supply chain.

Mainland China’s rise in automotive semiconductors has global implications

For global semiconductor suppliers, mainland China's rise presents a two-sided challenge. They must defend their positions in what is becoming the world's most important automotive semiconductor demand center while simultaneously preparing for mainland Chinese competitors to enter global markets.

Initially, competition is likely to be most intense in power semiconductors, microcontroller units (MCUs), analog devices and other mature-node categories. Over time, however, domestic companies are moving toward higher-value cockpit, intelligent-driving and centralized-compute processors. Their substantial domestic market gives them something especially important in automotive semiconductors: scale for validation, commercialization and continuous improvement.

Significant constraints remain. Advanced-node manufacturing access, semiconductor equipment restrictions, automotive-grade validation requirements and trade barriers could slow the international expansion of mainland Chinese suppliers. Global incumbents, such as Infineon, Nvidia, NXP Semiconductors, Renesas Electronics, STMicroelectronics and Texas Instruments, retain strong technology portfolios and established relationships with automakers and tier 1 suppliers.

However, the direction of travel is clear. Mainland China's importance to the automotive semiconductor market is no longer defined simply by the number of chips it consumes. Chinese automakers are influencing processor design, domestic suppliers are moving into higher-value applications, manufacturing capacity is expanding and policy is reinforcing deeper integration between the automotive and semiconductor industries.

By the end of the decade, mainland China is therefore likely to influence not only where automotive chips are consumed, but also how they are designed, sourced, manufactured and priced. That transformation makes the country not simply the industry's largest demand center, but increasingly one of the principal forces shaping the next generation of the global automotive semiconductor value chain.
