• Double/triple cropping – Intensive rice-wheat rotations in Yangtze Delta; new early-ripening varieties (Champa rice).

Economic Expansion

• Internal trade – Grand Canal, coastal shipping, regional specialization (silk, tea, porcelain, cotton).
• Silver inflows – Spanish Manila galleons (Potosi silver) monetized economy, facilitated tax payment, commerce.
• Urbanization – Cities >1M (Beijing, Nanjing, Suzhou, Hangzhou); proto-industrial workshops.

Political Stability

Checks on Growth

Periodic catastrophes: Ming fall (1644) wars, Qing conquest, Taiping Rebellion (1850–64, 20–30M dead), 1876–79 Northern Chinese Famine (9–13M). Net trend: ~150M (1600) → ~430M (1850).
