The Kondratieff Wave theory, proposed by Russian economist Nikolai Kondratieff, describes long-term economic cycles of approximately 50-60 years in capitalist economies. Each cycle consists of four phases: Prosperity, Recession, Depression, and Recovery.
📖 Formal Introduction
The Kondratieff Wave theory (Kondratieff Long Wave theory) is a macroeconomic theory about long-term economic cycles, proposed by Soviet economist Nikolai Kondratieff in 1925. The theory posits that capitalist economies experience long cycles of 50-60 years, each driven by technological revolutions and consisting of four phases: Prosperity (new technologies drive rapid economic growth), Recession (growth slows), Depression (economic downturn), and Recovery (laying the foundation for the next prosperity). Five complete Kondratieff cycles have been observed in history, driven respectively by steam engines, railroads, electrification, automobiles/petroleum, and information technology. This theory is crucial for understanding long-term economic trends, technological innovation cycles, and industrial structural changes.
💬 Plain Language Introduction
The Kondratieff Wave explains that: the economy doesn't just keep rising or falling; instead, it has large ups and downs like ocean waves, with a complete wave lasting about 50-60 years. Each wave is driven by a major technological revolution: the first was the steam engine (1770s), the second was railroads (1830s), the third was electricity (1890s), the fourth was automobiles and petroleum (1940s), and the fifth was computers and the internet (1990s). Each cycle experiences four seasons: "Spring" (Prosperity), "Summer" (Recession), "Autumn" (Depression), and "Winter" (Recovery). We are currently (2026) in the "Autumn" of the fifth Kondratieff Wave, and AI may be the seed for the sixth wave. Understanding the Kondratieff Wave helps you see the big picture and make better life and investment decisions.
📈 Prosperity
New technological revolution drives rapid economic growth, active investment, full employment, and rising prices.
📉 Recession
Economic growth slows, investment decreases, unemployment rises, and market confidence declines.
📊 Depression
Economic activity reaches its lowest point, massive unemployment, falling prices, and heightened social tensions.
📊 Recovery
Economy gradually recovers, new technologies emerge, laying the foundation for the next prosperity.

In the Depression phase of the 5th Kondratieff Wave (2020-2030)
Post-COVID-19 economic adjustment period, coinciding with the critical period of AI technology explosion. History shows that depressions often nurture the technological seeds for the next prosperity. Current generative AI, quantum computing, and new energy technologies may become the driving forces for the 6th Kondratieff Wave.
💡 According to the Kondratieff theory, we may enter the Recovery phase after 2030, with the Prosperity phase of the 6th wave beginning around 2050.
