A look at China's efforts to grow its chip industry by focusing on the most demanded and basic technologies, such as microcontrollers and power supply chips
most in demand in the shortage. w/ @lizalinwsj https://www.wsj.com/... Jonathan Cheng / @jchengwsj : @DanStrumpf @lizalinwsj China is slated to build 31 major semiconductor factories, known as fabs, between now and 2024—more than the 19 coming online in Taiwan, the next-biggest builder of chip fabs, and the 12 expected in the U.S. @rachelliang5602 @raffaelehuang https://www.wsj.com/... Liza Lin / @lizalinwsj : 1/ Thread: @DanStrumpf and I found China is leading the world in the building of new semiconductor factories... A move that could eventually make Western countries reliant on China for the supply of many basic chips used in mobile phones, cars, electronics https://www.wsj.com/...
Context & Ripple Effects
The chip shortage traced to a decade of capacity chasing higher-margin cutting-edge nodes left mature-node basics like microcontrollers and power chips undersupplied — and China's answer is to build where demand actually sits. The WSJ reporting finds China slated to bring 31 major fabs online by 2024, more than Taiwan's 19 or the U.S.'s 12, deliberately aimed at the most-demanded basic technologies rather than the leading edge.
That buildout is one thread in a longer self-sufficiency arc: TechInsights later measured China's chip self-sufficiency rate climbing from ~14% in 2014 to 23% in 2023, while SEMI put China at a third of global chip-equipment sales as it works around US tools. The Western countermove — 40+ proposed US projects worth ~$200B since 2020 — targets the same strategic realization that chips are now economic infrastructure.
First-order effects
- Western buyers of phones, cars, and electronics gain a new concentrated source for basic chips: if China's 31 new fabs come online on schedule, mature-node supply shifts toward Chinese fabs faster than toward Taiwanese or American ones.
- Taiwan and the U.S., building 19 and 12 fabs respectively over the same window, see their relative share of new global capacity fall even as their absolute buildouts grow.
Second-order effects
- If basic-chip supply consolidates in China, Western governments' subsidy programs face pressure to extend beyond leading-edge logic into mature-node capacity, since the shortage exposed exactly those commodity parts as chokepoints.
- Equipment and materials suppliers benefit regardless of geopolitics — with China already the largest buyer of chipmaking tools, more Chinese fabs deepen that dependence even as Washington tightens tool export controls.
Third-order effects
- The pattern points toward a bifurcated semiconductor map: China achieving volume dominance in mature-node basics while the West concentrates subsidies on the leading edge, leaving global electronics supply chains straddling both blocs.
- Sanctions appear to be accelerating rather than slowing Chinese capacity formation — if that holds, export controls become a race between restriction and substitution, with self-sufficiency rates as the scoreboard.
The trend: Global fab construction is splitting along geopolitical lines, with China racing to own high-volume basic-chip production while US industrial policy pulls leading-edge capacity back onshore.
