China's Special Economic Zones

Starting in 1980, China designated spots like Shenzhen, Zhuhai, Shantou, and Xiamen as Special Economic Zones. Inside them, the usual rules of a planned economy were suspended: foreign companies could own factories outright, set wages, keep profits, and export goods with low tariffs and light regulation. Outside the zones, the state still planned production, owned most industry, and controlled prices. The zones were a controlled experiment. If capitalism worked, Beijing could expand it; if it caused unrest, the fence around the zone contained the damage.

The strategy worked almost too well. Foreign factories poured into the coast, and coastal provinces like Guangdong grew rich on exports and manufacturing jobs while interior provinces like Gansu or Guizhou stayed tied to agriculture and state firms. Income per person on the coast pulled far ahead of the interior over the 1980s and 1990s, and that income gap became one of the defining features of China's reform era. Jobs don't sit still when wages diverge that much: millions of interior workers migrated toward coastal cities, creating a massive internal labor flow often called the floating population, since many lacked full residency rights where they worked.

None of this touched the political system. The Communist Party ran the zones as tightly as anywhere else: one party, controlled media, no independent courts or free elections. That separation is the core lesson of this topic. Market reform changed who could buy, sell, hire, and invest; it never changed who could rule. Pair this zone-by-zone liberalization with the uneven development it produced, and you get the inequality and migration pressures that still shape Chinese politics today.
