The trade war is forcing an upgrade of China's semiconductor industry, accelerating domestic substitution and bringing about historic opportunities.

Introduction  

Since 2024, the United States has continuously escalated tariffs and technological blockades against China's semiconductor industry, from imposing tariffs of up to 50% to expanding the export control list, aiming to curb China's high-tech development. However, these measures have unexpectedly activated the resilience of China's semiconductor industry chain. The process of replacing domestic equipment has accelerated, and domestic enterprises are shifting from passive defense to active breakthroughs. An industrial transformation centered around technological autonomy and supply chain security is quietly unfolding.

The Double-Edged Sword of the Tariff War: The Forced Effect Appears

Policy Upgrades: In May 2024, the United States raised semiconductor tariffs from 25% to 50%; in December of the same year, 136 Chinese semiconductor companies were added to the export control list; in March 2025, traditional chips (28nm and above processes) became new tariff targets.

Long-Term Industrial Chain Restructuring: The United States requires foreign companies to transfer their production capacity in China before 2026, threatening China's status as the "world's largest semiconductor manufacturing base," but also forcing the domestic supply chain to fill the gaps.

The Driving Force of Domestic Substitution

Strong Policy Support: The National Integrated Circuit Industry Investment Fund Phase III added 300 billion yuan, focusing on supporting equipment and material research and development. Local policies have increased tax reductions and exemptions, talent subsidies, and the capital market's confidence in domestic equipment companies such as Huatian Technology has increased.

Accelerated Domestic Substitution: The tariff war has forced companies to accelerate the pace of domestic substitution, and market demand for domestic equipment has increased. Chinese companies already have certain production capacity and cost advantages in the field of traditional chips (28nm and above processes). With continuous technological advancements and increased R&D investment, they are expected to achieve greater breakthroughs in the field of mature process equipment, gradually improving the domestic rate.

Enhanced Technological Innovation: Faced with external pressure, Chinese semiconductor companies and research institutions have increased their efforts in independent research and development, actively exploring new technologies and processes, such as RISC-V architecture and Chiplet heterogeneous integration "overtaking on a curve" technologies, providing new paths and directions for the development of domestic semiconductor equipment and helping to improve the overall technological level and competitiveness of China's semiconductor industry.

Synergistic Development of the Industrial Chain: The tariff war has prompted China to strengthen cooperation with the semiconductor industries of countries and regions such as Europe, Japan, and South Korea, supplementing shortcomings in key technologies through international cooperation and promoting the synergistic development of the industrial chain. At the same time, cooperation between upstream and downstream enterprises in the domestic semiconductor industry chain has become closer, jointly overcoming technical challenges and improving the industry chain's independent and controllable capabilities.

Conclusion  

The tariffs and technological blockades imposed by the United States are essentially a power struggle in the context of the receding tide of globalization. However, China's domestic substitution in the semiconductor industry has shifted from "policy-driven" to "market-driven." In this ultimate contest of efficiency, technology, and scale, Chinese companies must face the pain and seize historical opportunities—when the smoke clears, the real deciding factor will still be the independent innovation and ecosystem construction of the industrial chain.
