Time Series Data

Fiscal-Military Relationship Analysis

• Fiscal capacity enables military capacity: Increasing tax revenue (2.1B → 6.2B) enables large standing armies (1.2M → 1.8M soldiers)
• Military expenditure strains fiscal systems: Military spending ranges from 36% to 62% of tax revenue, creating fiscal pressure
• Fiscal-military cycles: Expansion cycles (Song, Ming) → Strain cycles (Yuan) → Fiscal capacity enables recovery
• Fiscal sustainability: Fiscal capacity enables military sustainability despite high military spending
