美国最新出口管制推动中国转向国产芯片

China's shift to local chips
gains momentum from latest US export controls
Industry associations urge companies to switch, saying
American semiconductors are ‘no longer safe or reliable’

China has finally said aloud what was once only discussed
behind closed doors: the country must rid itself of US chips.
Four government-backed industry associations, representing the
bulk of China’s semiconductor demand, issued co-ordinated
statements this week urging member companies to rethink purchases
of American silicon that three of them deemed as “no longer safe or
reliable”.
“Be cautious when purchasing US chips,” the four associations
said, urging their members to look for Chinese or other foreign
suppliers instead.
The directives came amid the latest tit-for-tat salvo between
Beijing and Washington over the foundational technology, an
exchange that has laid bare their intensifying competition and
added momentum to the development of increasingly separate
international supply chains.
In an unusually swift response on Tuesday, Beijing banned the
shipment of key minerals and metals to the US, just hours after
American officials unveiled new export controls designed to
“degrade” China’s ability to make the most advanced chips.
The latest US controls include tougher restrictions on
shipping semiconductor manufacturing tools to China and a ban on
exports of advanced memory chips needed in artificial intelligence
hardware.
In response, China prohibited the export to the US of gallium,
germanium, antimony and superhard materials, and imposed stricter
controls on graphite.
Its action signalled a new willingness on Beijing’s part to
confront directly US efforts to cut the country off from advanced
technology. In talks with President Joe Biden last month, Chinese
leader Xi linked Washington’s tech controls to stymying China’s
right to development, calling it a red line for the first
time.
“Beijing has grown increasingly frustrated with US technology
controls and has signalled it is prepared to respond in ways that
create economic pain for US companies and the US economy,” said
Paul Triolo, a tech expert at Albright Stonebridge Group.
China’s curbs on materials for making semiconductors,
batteries and military hardware will cause headaches for the US
defence department and American companies that have already been
scrambling to find other suppliers and substitutes for critical
materials in supply chains controlled by Beijing.
The country is the world’s main supplier of gallium and
germanium. The US Geological Survey in October estimated a complete
export ban on both would lower US GDP by $3.4bn.
Accelerated efforts to eliminate US chips could hurt a broad
swath of American semiconductor groups. An executive at a European
chip design company said they had already been receiving calls from
nervous Chinese clients wanting to confirm that they were not
American.
“This is the first time private companies have been directed
to cut out US chips,” the executive said. “It’s not a direct order
but will have a chilling effect.”
Analysts at Bernstein estimate Chinese groups have the power
to influence sourcing decisions for the roughly 40 per cent of the
global smartphone market they control and the 23 per cent of the
computer market supplied by companies that include the world’s
largest PC maker Lenovo.
Customers in China, for example, contributed 27 per cent of
sales last year for Intel, America’s stumbling traditional chip
champion. Artificial intelligence chip giant Nvidia drew 17 per
cent of sales from the country. Arizona-based Onsemi estimates its
chips are in half of China’s electric vehicles. Mobile processor
maker Qualcomm derived about half of its $39bn in annual revenue
from China.
“The risks of such concentration are exacerbated by [US-China]
trade and national security tensions,” Qualcomm warned
investors.
But Wall Street has largely brushed off concerns that US chips
could be designed out of Chinese devices. Lin Qingyuan, an expert
on China’s semiconductor self-reliance programme at Bernstein, said
that in the near and medium term, investors did not need to worry.
“If China was able to get rid of US chips, they would have
already,” he said.
While government directives have accelerated localisation
efforts, companies would still prioritise performance, said Lin,
noting that the latest rhetoric from industry associations was most
likely to change purchasing behaviour in mature chips.
Nevertheless, China’s localisation drive has been expanding,
with government and state-owned groups being told to buy computers
without Intel and AMD processors.
Even foreign companies are increasingly switching to local
semiconductors, with German car parts supplier Bosch highlighting
its “localised chip solution” for a steering system at a supply
chain expo in Beijing last month. “This is our local product for
the local market,” said a sales manager.
China’s State Grid proudly displayed electrical equipment
powered by Chinese central processing units and microprocessors.
“New products all use local semis,” said an engineer.
Analysts said it was too soon to gauge the impact of the new
US controls on China’s chip industry. Ahead of the bans, there had
been months of building up stockpiles of equipment and
high-bandwidth memory (HBM) chips needed for AI processors.
Tilly Zhang, a semiconductor analyst at Gavekal, said no
Chinese company had been able to achieve mass production of HBM
chips, though memory group CXMT was trying.
“Companies have made meaningful progress in replacing American
tools in the past few years thanks to previous export controls,”
said Bao Linghao, an analyst at Trivium. “Piecemeal controls will
help China to build a more robust chip supply chain over the long
term.”
Lin at Bernstein agreed that the impact on China’s
semiconductor equipment makers could be limited. “They’ve been
working to de-Americanise their supply chains for more than three
years,” he said.
Chinese equipment makers have already shifted to Japanese and
European component suppliers with equivalent products that would
not be affected by the export controls, he said. Lin did not expect
the key US allies to unveil controls as tough as those from
Washington, if they did at all.
“We expect [switching to other non-US suppliers] to continue
until local suppliers can catch up,” he said.
