Kunshan

Kunshan may be the richest place in China that most outsiders cannot place on a map. This county-level city between Shanghai and Suzhou had about 2.13 million residents at the end of 2024 and generated CNY 538.0 billion ($74.7 billion) of GDP, the kind of output normally associated with provincial capitals rather than an administrative unit below them.

The official story is location. Kunshan sits only 10 metres above sea level on the flat Jiangsu plain, close enough to plug into Shanghai's port, finance, and airport infrastructure while benefiting from lower land and labour costs. The deeper story is that Kunshan became the mainland's most successful host for Taiwanese manufacturing capital. Electronics firms built factories there not because the city had an old industrial pedigree, but because local government created a stable habitat for cross-strait supply chains that wanted mainland scale without giving up Taiwanese managerial networks.

That choice compounded. Once Foxconn, Compal, Wistron, and layers of component suppliers clustered there, the next assembler had reason to come as well. Managers could hire engineers who already understood notebook and handset production, suppliers could serve multiple anchor customers from the same industrial parks, and buyers could source everything from casings to connectors within one drive. Kunshan did not invent the personal computer. It perfected the industrial ecology around it. The city also learned the downside of that density in 2014, when a dust explosion at a metal-polishing plant killed more than 140 workers and exposed the human cost of shaving seconds off global electronics margins.

The biological parallel is the termite mound. Termites win by building an environment whose structure makes complex coordination routine. Kunshan follows the same niche-construction logic, reinforced by mutualism between Taiwanese capital, mainland infrastructure, and Shanghai market access. Its moat is not civic glamour. It is the accumulated habit of suppliers, managers, and customers who already know the next factory can be plugged into the system.
