Introduction

Semiconductors are the “brains” of the modern economy, embedded in everything from smartphones and cloud computing platforms to fighter jets and electric vehicles. They sit at the center of strategic rivalry between the US and China, where control over advanced microchips is increasingly synonymous with economic power and national security. Global semiconductor revenues have surpassed US$400 billion annually, while the broader digital economy they enable runs into trillions of US dollars.

China’s ambition to become a semiconductor superpower is driven by a stark reality: it is the world’s largest importer of microchips. In recent years, China’s chip imports have exceeded US$300 billion annually — more than its crude oil imports by value. This dependence is seen as a strategic vulnerability, particularly as export controls tighten and geopolitical tensions deepen.

The strategic importance of semiconductors

Semiconductors underpin critical sectors including artificial intelligence (AI), quantum computing, 5G telecommunications, aerospace, defense, and advanced manufacturing. Innovative chips, especially those at nodes below 10 nanometers, are essential for high-performance computing and advanced AI systems.

Manufacturing these chips requires extreme precision and enormous capital. A leading-edge fabrication plant can cost between US$10 billion and US$20 billion, reflecting the extraordinary complexity of advanced lithography, materials science, and process engineering. The ecosystem involves design software, specialized manufacturing equipment, chemicals, wafers, packaging, and testing. Each segment is often dominated by a handful of firms concentrated in specific countries.

The US leads in chip design and electronic design automation tools. Taiwan and South Korea dominate advanced fabrication and memory production. Japan and Europe supply critical equipment and materials. China, despite being the largest consumer, remains dependent on foreign suppliers for key technologies.

China’s microchip ambitions

China’s strategy centers on reducing foreign dependence and building indigenous capacity across the semiconductor value chain. National initiatives have mobilized tens of billions of US dollars to support domestic fabrication plants, equipment manufacturers, and design champions.

State-backed investment funds have injected US$20–US$30 billion, and more into strategic projects aimed at accelerating technological catch-up. The objective is not merely economic upgrading but technological sovereignty.

Despite substantial investment, progress has been uneven. Chinese firms have made gains in mature-node manufacturing, which remains vital for automotive, industrial, and consumer electronics applications. However, leading-edge nodes remain constrained by limited access to advanced manufacturing equipment and intellectual property.

Semiconductor self-sufficiency is not a short-term endeavor. The technological frontier requires decades of accumulated expertise, cross-border collaboration, and deep integration into global innovation networks.

Export controls and technology choke points

Export controls have become a central feature of semiconductor geopolitics. The US has imposed restrictions on the transfer of advanced chips, manufacturing equipment, and design tools to certain Chinese entities. These measures aim to slow China’s access to innovative technologies, particularly those with military or dual-use applications.

One of the most significant choke points lies in advanced lithography equipment, including extreme ultraviolet systems, which are indispensable for fabricating chips at the most advanced nodes. Without access to such equipment, achieving parity in leading-edge production becomes extraordinarily difficult.

Export controls extend beyond hardware to include software, intellectual property, and talent flows. The semiconductor industry’s globalized architecture means that restrictions in one segment can reverberate across the entire ecosystem.

The return of industrial policy

The scale and strategic importance of semiconductors have prompted a resurgence of industrial policy worldwide. Governments are offering subsidies, tax incentives, and research grants to attract fabrication plants and strengthen domestic supply chains.

The high capital intensity of advanced fabrication — often exceeding US$10 billion per facility — makes public support a decisive factor in location decisions.

China’s industrial policy combines financial incentives, procurement preferences, and long-term strategic planning. The approach seeks to cultivate national champions while reducing exposure to external pressure. At the same time, other major economies are reinforcing their own semiconductor strategies, creating a competitive landscape of subsidy programs and strategic alliances.

Industrial policy can accelerate capacity building, but it also risks overcapacity, inefficiencies, and geopolitical fragmentation.

Supply chain vulnerability and resilience

The pandemic exposed the fragility of semiconductor supply chains. Disruptions led to severe shortages in automotive and consumer electronics sectors, with production halts costing billions of US dollars globally.

Semiconductor production depends on just-in-time logistics, highly specialized inputs, and precise coordination across continents. Concentration of advanced fabrication capacity in a few geographic locations increases systemic risk.

China’s push for domestic capacity reflects a broader global emphasis on resilience. Diversification, inventory buffers, and regional production hubs are becoming policy priorities. Yet complete decoupling remains unrealistic. No single country controls the full semiconductor value chain, and replicating advanced ecosystems requires enormous financial and human capital.

Technology competition and bifurcation

The intensifying rivalry between the US and China risks creating bifurcated technology ecosystems. Divergent standards, supply chains, and regulatory frameworks could fragment global markets. Firms may face pressure to align with one ecosystem or another, complicating business models and raising costs.

Technology bifurcation can reduce economies of scale and slow innovation by limiting cross-border collaboration. The semiconductor industry has historically thrived on international cooperation among designers, equipment manufacturers, materials suppliers, and research institutions.

At the same time, competition can drive investment and innovation. Strategic rivalry has elevated semiconductors to the forefront of national policy agendas, accelerating funding for research and development.

Conclusion

China’s microchip ambitions are rooted in economic necessity and strategic calculation. With annual chip imports exceeding US$300 billion and fabrication plants costing US$10 billion to US$20 billion, the stakes are immense.

Semiconductors have become the “oil of the digital age,” essential to artificial intelligence, defense systems, telecommunications, and advanced manufacturing. Export controls, industrial policy, and strategic investment are reshaping the global semiconductor landscape.

China’s progress toward self-sufficiency will depend on sustained investment, access to critical technologies, and the development of domestic innovation ecosystems. The broader global system faces a delicate balance between resilience and openness.

The semiconductor industry remains deeply interconnected. Efforts to localize production and secure supply chains must contend with the reality of a complex, capital-intensive, and highly specialized global network. Whether the future is defined by fragmentation or renewed cooperation will shape not only the semiconductor sector but the trajectory of the digital economy itself.
