Deyang

Deyang's equipment-manufacturing value added rose 18.8 percent in 2023, which is why a city of about 735,070 people matters to power grids and reactor builders far beyond Sichuan. Deyang sits 501 metres above sea level on the Chengdu plain and is usually introduced as a heavy-industry city. That is true but incomplete. The real story is that Deyang makes the kind of machinery other places cannot improvise on short notice: turbines, large forgings, nuclear components, and other long-cycle hardware where failure is ruinously expensive.

That specialization gives the city unusual staying power. Local trade officials reported that just five AEO-certified firms, about 1 percent of Deyang's foreign-trade companies, generated 23.2 percent of the city's export value in the first eleven months of 2024. This is not a broad consumer-export ecosystem. It is a concentrated trust market built around a small number of manufacturers whose products have to clear engineering, safety, and delivery tests that newcomers cannot fake. Dongfang Electric, Erzhong, and the supplier web around them anchor a production habitat that has been repurposed from old heavy industry into what officials now describe as a clean-energy equipment base. The point is not that Deyang abandoned big metal. The point is that it learned how to point the same metallurgical muscle at hydropower, wind, thermal generation, and nuclear projects.

That is the Wikipedia gap. Deyang is not just an industrial city near Chengdu. It is a repository of difficult-to-recreate manufacturing memory. Once a city learns how to cast, forge, machine, inspect, transport, and service very large equipment, each successful project makes the next contract easier to win. The cluster becomes self-reinforcing even without the glamour of a tech hub.

Modularity explains the economics because giant machines are assembled from many precise subsystems produced by specialized firms. Network effects explain why buyers, engineers, and suppliers keep converging on the same city. Costly signaling explains why certifications and delivery history matter so much in export markets where one defective component can delay a power project for years.

Biologically, Deyang resembles a cathedral termite colony. Termites create giant, load-bearing structures through repeated, specialized tasks that only make sense inside a mature collective. Deyang does the same with turbines and forgings.
