Never mind that China has gotten less growth from each unit of new investment since its big infrastructure binge of 2008. The Communist Party continues to build because it’s full of engineers and also because Marxist-Leninists don’t want to cede economic agency to the people.

China would be better off if it built less and built better. But we should also resist judging it by the standards of the United States, which is frankly underprovisioned in public infrastructure. Because there is perhaps one thing worse than an overactive state that can’t stop moving— and that is a state that can’t move at all.

By the mid-2010s, Chinese companies figured out how to make all the German tools, as well as the entirety of the solar value chain. The plunge on solar power costs over the last decade has been driven less by breakthroughs in science— which is the United State’s strong suit— than by efficient production, which is China’s strength. The beneficiaries are not only the climate but also China’s national power.

Science matters of course. China remains weak in chips and aviation in part because these are much more scientifically complex industries than solar. Not every technology improves through iterative adjustments to manufacturing processes, but a great deal can follow its logic. When lots of companies are doing similar things, in a brutally competitive environment where profit margins are small, they establish communities of engineering practice like Shenzhen. These factories will never be as glamorous as the desirable branding represented by Apple or Tesla. Every day, millions of workers go to factories to build up technological process knowledge.

The engineering state still has many strengths. There is one thing I haven’t changed my mind about since 2017: I remain more confident than ever that China will become a technological leader in manufacturing industries.

Marxists like to reason through contradictions. What is the central contradiction facing China? I submit that we must reconcile two realities when we read the headlines. First, the rich, the creative, and the desperate have chosen to rùn from the economic and political gloom that pervades Xi’s third term. Second, the manufacturing sector continues to go from strength to strength in the mastery of electric vehicles, clean technology, and other advanced technologies.

How might they be reconciled? With the idea of the engineering state.

And the focus on building is winning China some degree of support in developing countries as well.

Exporting China’s infrastructure is core to the Belt and Road Initiative (BRI), one of Xi’s signature initiatives. Chinese firms have taken their expertise in building roads, bridges, railways, tunnels, dams, and power plants abroad. And the sometimes also bring the sorts of surveillance systems and censorship tools that find eager customers among autocratic leaders. They have gone on a spending spree overseas, with $1 trillion worth of loans outstanding in 150 countries.

Even if the United States is able to outclass China in diplomacy, finance, and innovation, the contest between these two great powers is going to be close if the United States can't build anything in the physical world.

The strongest wind in China’s sails is the entrenched technological workforce that preserves process knowledge that I wrote about in Chapter 3 on tech power. Though 50 percent of China’s economy might be dysfunctional, 5 percent is doing superbly well (an approximation I borrow from Greg Ip at the Wall Street Journal).
