2 . A shortage of semiconductors (半导体) has helped firms such as Nvidia, whose chips (芯片) power everything from video gaming to machine learning and data centres. But boom time for sellers means misery for buyers. Carmakers, whose products have become computers on wheels, are among the victims. Analysts say the industry might build around 5 million fewer cars this year, all for want of the chips. Apple and Microsoft have also warned that they will be affected.
The shortage is the result of a sudden rise in demand. Chipmaking has been enjoying strong growth for decades as computers have stepped into every corner of society. But there was a strong upward trend during the pandemic. Locked-down consumers shopped online, had meetings remotely, and killed time with video-streaming and videogaming.
The crisis has had three consequences, two encouraging and one less so.
The first is an investment boom. Big producers such as Intel, Samsung and TSMC are planning to spend hundreds of billions of dollars on extra capacity (产能) over the next few years. As in many markets, high prices are the best cure for high prices.
The second is that the chip industry’s customers are adapting. too. When demand fell early in the pandemic, carmakers cut their orders with chipmakers. Following Tesla, Volkswagen has announced plans to develop driver-assistance chips in-house.
Unwelcome effect has been a sudden rise of techno-nationalism. America is planning to hand out billions of dollars to attract chipmakers back from East Asia. Europe wants to double its share of global production, to 20%，by 2030. Even Britain has declared the fate of a small chip factory in Wales to be a matter of national security.
Chips have come to occupy what used to be called the “commanding heights” of an economy, in the way that car factories did in the 20th century. But as last century’s governments discovered, subsidies (补贴) lend 10 oversupply. Personally, the chip shortage is mostly a self-solving problem. Governments should resist the temptation to scc themselves as saviours (救星).
