Jack Ma says he's ready for China to make semiconductors at home. It's a longstanding goal for the Chinese government. And thanks to a recent crackdown
on certain technology exports by the U.S., it's now a critical one. The
question is whether China can finally conquer this challenge after
decades of failures.
Semiconductors
are the building blocks of electronics, found in everything from flip
phones to the servers that make up a supercomputer. Although China long
ago mastered the art of making products with semiconductors produced
elsewhere (the iPhone is the most famous example), it wants to move
beyond being a mere assembler. It aspires to being an originator of
products and ideas, especially in cutting-edge industries such as
autonomous cars. For that, it needs its own semiconductors.
That's
no small challenge. China is currently the world's biggest chip market,
but it manufactures only 16 percent of the semiconductors it uses
domestically. It imports about $200 billion worth annually -- a value
exceeding its oil imports. To cultivate a domestic industry, the
government has slashed taxes for chip makers and plans to invest as much
as $32 billion to become a world leader in design and manufacturing. Yet as history shows, spending won't be enough.
China's earliest semiconductor was built in 1956, not long
after the technology was invented in the U.S. But thanks to the turmoil
of the Cultural Revolution, whatever momentum its engineers and
scientists had was soon lost. When the country reopened for business in
the 1970s, officials quickly realized that semiconductors would be a key
part of any future market-based economy.
Almost
from the start, though, central planning proved to be a serious
impediment. Early government ideas included importing secondhand
Japanese semiconductor lines that were outdated before they were even
shipped. Expensive efforts to build a domestic industry from scratch in
the 1990s faltered due to bureaucracy, delays and a lack of customers
for the kind of chips China was making.
Another weakness was a
lack of capital. For decades, labor-intensive industries -- such as
assembling mobile phones -- were the route to riches in China,
attracting investment from entrepreneurs and bureaucrats alike. Making
semiconductors, by contrast, requires billions in up-front capital and
can take a decade or more to see a return. In 2016, Intel Corp. alone
spent $12.7 billion
on R&D. Few if any Chinese companies have that capacity or the
experience to make such an investment rationally. And central planners
typically resist that kind of risky and far-sighted spending.
China
seems to recognize this problem. Since 2000, it has shifted away from
subsidizing semiconductor research and production, and toward making
equity investments, in the hope that market forces could play a larger
role. Yet funds continue to be misallocated: Over the past 18 months,
there's been a spate of government-juiced overinvestment
in semiconductor plants, many of which lack sufficient technology.
Those that eventually open will likely contribute to a glut in memory
chips, spelling financial trouble for the domestic industry.
But
perhaps the biggest long-term challenge for China is technology
acquisition. Though the government would like to develop an industry
from the ground up, its best efforts are still one or two generations
behind the U.S. A logical solution would be to buy technology from
American companies or form partnerships with them. That's the route taken by cutting-edge firms in Japan, South Korea and Taiwan.
Yet China can't do the same. Its efforts to purchase
American semiconductor companies (often at huge premiums) are regularly
blocked for security reasons. Japan, South Korea and Taiwan have put
Chinese acquisitions under similar scrutiny. By one accounting,
China has made $34 billion in bids for U.S. semiconductor companies
alone since 2015, yet completed only $4.4 billion in deals globally in
that span.
Despite
these impediments, China has actually made substantial strides in
recent years. Companies such as Shanghai-based Spreadtrum Communications
Inc. are designing semiconductors for mobile phones and other
technologies, then outsourcing production to foreign plants. Meanwhile,
China's considerable investment in factories that make older
technologies has provided managers, engineers and scientists some
crucial lessons in how to run a semiconductor fabrication business.
None
of these efforts will provide the shortcuts that government officials
-- and Jack Ma -- seem to want. But they might offer the building blocks
for an industry that China has spent half a century trying and failing
to create.
