China’s Manufacturing Overcapacity Problem: Who Pays the Price?

China’s manufacturing overcapacity affects global markets. Solar capacity 2.4x demand, steel excess 300M tonnes, batteries at 60% utilization.

From solar panels to steel, Chinese overcapacity is reshaping global markets

China’s manufacturing overcapacity is no longer a niche complaint from Western trade officials — it’s a global economic reality affecting prices, investment, and employment across multiple sectors. The issue sits at the center of the US-China trade dispute and is the primary target of the USTR’s ongoing Section 301 investigation into excess capacity.

The sectors with the most severe overcapacity include:

Solar panels: manufacturing capacity 2.4x global demand, prices below $0.10/watt
Steel: production capacity exceeds domestic demand by roughly 300 million tonnes
Lithium-ion batteries: capacity 1.8x demand, utilization rates below 60%
EVs: 200+ brands competing for a market that can support 15-20
Cement, glass, and aluminum: chronic overcapacity dating back a decade

How overcapacity happens

China’s economic model encourages overcapacity by design. Local governments compete to attract manufacturing investment with subsidies, cheap land, and tax breaks. When multiple provinces each build a “national champion” in the same industry, the result is excess capacity that no single province wants to cut.

“Every governor wants a solar panel factory. Every governor wants an EV factory,” said a researcher at the Chinese Academy of Social Sciences who asked not to be named. “Nobody wants to be the one who didn’t build it when the industry was growing.”

The global impact

Chinese overcapacity depresses prices globally. Steel prices in Europe fell 15% in 2025 as Chinese exports surged. Solar panel prices worldwide are at historic lows, which is great for deployment but devastating for non-Chinese manufacturers — dozens of European and American solar factories have closed or reduced operations since 2023.

The EU imposed anti-dumping duties on Chinese steel in 2025 and is investigating Chinese EV subsidies. The US has tariffs of 100% on Chinese EVs and 50% on Chinese solar cells. But tariffs only partially address the issue — Chinese manufacturers often route products through third countries (Vietnam, Malaysia, Thailand) to avoid duties.

China’s response

Beijing acknowledges the overcapacity problem but frames it as a market-driven correction rather than a policy failure. The government has tightened financing for new capacity in some sectors (steel, cement) while continuing to support strategic industries (EVs, batteries, semiconductors).

The “supply-side structural reform” campaign, launched in 2015, has had mixed results. In steel, capacity was reduced by 150 million tonnes between 2016 and 2020 — but new capacity in electric arc furnaces has partially offset those cuts. In solar, no meaningful capacity reduction has occurred; instead, weaker manufacturers are expected to exit the market through bankruptcy.
