But control of a factory would not automatically confer the ability to keep it producing: advanced chipmaking relies on foreign equipment, materials, software and expertise as well as Taiwanese facilities and workers. That distinction is central to the question raised by the phrase “silicon hegemon”: could China gain decisive influence over Taiwan’s chip industry without invading, and what would such influence mean for global economic stability?
What does “silicon hegemon” mean?
A hegemon is a state with preponderant power and status that exerts dominant influence or authority. In this context, the term describes the strategic advantage a country could gain from controlling or disrupting Taiwan’s exceptionally important advanced-chip production. It is an argument about influence over an industry and its supply network—not simply a claim that one country owns the world’s semiconductor companies.
The phrase appears in Pablo Valerio’s EE Times article “The Silicon Hegemon”. A related question—whether China could take over Taiwan’s semiconductor industry without a full invasion—is the subject of a September 27, 2023 analysis by Gabriel Collins and Andrew S. Erickson at Rice University’s Baker Institute for Public Policy.
How much of the world’s chipmaking is concentrated in Taiwan?
The estimates depend on the source’s wording and market definition, so they should not be treated as directly interchangeable. Valerio’s 2026 EE Times article says Taiwan accounts for about 20% of world semiconductor output and that TSMC holds more than 90% of the cutting-edge-chip market. Collins and Erickson’s 2023 Baker Institute essay says Taiwan produces 60% of the world’s semiconductors and over 90% of the most advanced chips. Those publications do not establish that the figures measure the same category in the same way.
#1 Best Overall
The figures nonetheless point to an important distinction: Taiwan’s significance is especially pronounced in advanced manufacturing. Valerio quotes Barcelona Supercomputing Center director Mateo Valero describing Taiwan’s pure-play foundry model as a global foundation for semiconductor design companies, and identifying technologies such as gate-all-around (GAA), Super Power Rail and chip-on-wafer-on-substrate (CoWoS) packaging as part of Taiwan’s role in the AI industry.
Why taking control of a fab would not be enough
A semiconductor fab is one node in a cross-border production network. Collins and Erickson describe designs made using American or British software, extreme ultraviolet (EUV) lithography equipment from a single Dutch company, and photoresists and specialty chemicals supplied largely by Japanese firms. The facilities also depend on specialized knowledge and the people who operate them.
That creates a gap between control and operability. Occupying facilities or obtaining corporate assets would not, by itself, transfer the foreign tools, materials, software, supplier relationships and expertise needed for uninterrupted production. The Baker Institute authors argue that workers and executives could refuse to cooperate with an entity controlled by the People’s Republic of China (PRC), while foreign suppliers and governments could constrain access to critical inputs.
- Facilities: Physical possession does not guarantee the ability to operate highly specialized equipment.
- Inputs: Lithography tools, chemicals, photoresists and design software come from outside Taiwan.
- People: A fab’s practical operation depends on cooperation and specialized expertise, not just ownership.
What could pressure short of invasion look like?
Collins and Erickson examine contingencies rather than predict what Beijing will do. They discuss military operations around Taiwan; interference with civilian, government or military traffic; and, in more escalatory cases, a blockade or seizure of outlying islands. The authors identify Kinmen, Matsu, Pratas and Itu Aba in their discussion, while noting that taking an outlying island could sacrifice surprise and mobilize opposition. The likelihood and consequences of these scenarios are uncertain.

It distinguishes nominal financial or physical control from the harder task of keeping production working when employees, suppliers and outside governments may not cooperate. It does not establish that any one pressure campaign would succeed.
Does Taiwan’s “silicon shield” protect it?
The “silicon shield” is the theory that Taiwan’s importance to the global economy helps deter military threats because disruption would impose costs far beyond the island. Valerio attributes the phrase to former Taiwan president Tsai Ing-wen’s 2021 Foreign Affairs article. The shield is a theory of deterrence, not a guarantee of safety.
Its logic can cut both ways. Dependence on Taiwan gives other economies a strong reason to avoid disruption, but concentration also creates a high-impact vulnerability. Valerio notes that export controls and China’s efforts to build domestic semiconductor capacity may test the shield’s assumptions. Neither that discussion nor the Baker Institute analysis proves that Taiwan is invulnerable or that conflict is inevitable.
What limits Taiwan’s ability to keep production resilient?
Chipmaking depends on more than equipment and materials. Valerio’s 2026 article discusses electricity demand, water recycling, labor availability and overseas expansion as factors affecting Taiwan’s semiconductor resilience. It reports that TSMC accounts for about 9% of Taiwan’s total electricity generation, with the share projected to rise to 12% by 2030. These are figures reported by EE Times; its cited support for them is not a primary utility or company dataset.
The article also cites an industry labor shortage of about 34,000 workers in May 2025, attributed to Taiwan’s Overseas Community Affairs Council, and says TSMC’s most advanced research and largest cutting-edge production remain concentrated in Taiwan despite facilities or plans elsewhere. The shortage figure’s scope is not established here beyond the EE Times account. Those details describe constraints and concentration, not a measured forecast of lost chip output.

A major interruption to Taiwan’s advanced-chip production could affect companies and economies well beyond Taiwan because the island’s fabs sit within a global network of chip design, equipment and materials suppliers. That is the economic risk behind the silicon-hegemon debate: influence over a concentrated, difficult-to-replace production base could create leverage, while disruption could transmit costs through the supply chain.
Valerio reports a Bloomberg estimate that a Taiwan-related crisis could have an impact of $10 trillion, or roughly 10% of global GDP. This is an estimate, not a measured loss or settled forecast; it should not be read as the certain cost of any particular scenario.
For personal-finance readers, the evidence supports treating semiconductor concentration as a source of broad economic uncertainty, not as a precise forecast for household costs, investment returns or a specific company’s performance. The cited analyses do not quantify those outcomes.

Overseas expansion can add geographic options, but it does not automatically recreate Taiwan’s full manufacturing ecosystem or remove the dependencies on foreign tools, materials and skills. Valerio reports that TSMC’s most advanced research and largest cutting-edge production remain concentrated in Taiwan. The available figures here do not establish how quickly overseas capacity might change that balance.
For governments and companies considering resilience, the useful distinction is between adding capacity in more places and being able to sustain production if Taiwan’s output is disrupted. Diversification can address geographic concentration; it cannot, on its own, ensure that every site has the same leading-edge capability or supply access.
How should readers interpret the takeover scenario?
The Baker Institute essay is a policy analysis published in 2023, not a current intelligence assessment. Its discussion of Chinese intentions, coercive tactics and possible allied responses is analytical judgment, and the authors characterize the scenario as low probability and high impact. Its practical warning is narrower and more durable: possession of semiconductor assets is not the same as the ability to operate them or preserve the network that supplies them.
That is why “silicon hegemon” is best understood as a question about leverage and resilience, not a claim that control of Taiwan’s fabs would automatically confer control of the entire semiconductor industry. Taiwan’s concentration in advanced chips matters to the global economy, but dependence on a wider international production system limits what any single actor can do with the factories alone.
