How China Became the World’s Factory (in 15 Minutes)

In 1979, Shenzhen was a fishing town of about 30,000 people. Today it's a city of 17.8 million — and China makes almost 30% of everything manufactured on Earth, more than the US, Japan and Germany combined. The usual explanation is cheap labour. But plenty of countries had cheap labour. Only one became the factory of the world. So what actually happened? In this visual explainer we follow the story from a secret contract signed by 18 farmers in 1978, through Deng Xiaoping's Special Economic Zones, the largest migration in human history, China's entry into the WTO, a building spree of roads, ports and power plants, and the supply-chain clusters that make China so hard to replace — all the way to EVs, solar, robots, "China + 1" and India's push to catch up. ⏱️ CHAPTERS 0:00 How did this happen? 1:17 Ground zero: China in 1978 2:49 The experiment: Deng & the Special Economic Zones 4:53 The workforce: 300 million people on the move 6:43 The rocket: joining the WTO 8:10 The machine: roads, power and ports 9:32 The real secret: supply-chain clusters 11:28 Moving up: EVs, solar and robots 12:46 Cracks in the factory & what comes next 14:03 Sources 📚 SOURCES World Bank (GDP per capita) · CSIS China Power & UN Statistics Division (manufacturing share) · Naughton, Brookings (1996) · National Bureau of Statistics of China (migrant workers) · Xinhua (Spring Festival travel) · Hong Kong Trade & Industry Department · Shenzhen Statistics Bureau · China Customs via FRED / Statista · Lloyd's List / Alphaliner (container ports) · Ember Global Electricity Review 2025 · China State Railway Group · IEA & REN21 · Wood Mackenzie (solar prices) · International Federation of Robotics · Bloomberg (iPhone production in India) · Natural Earth (map data) #China #Economics #Explained
