Kondratiev Cycle

Definition

Kondratiev cycle is a long-wave macro framework that links technology, production systems, capital investment, social structure, and asset prices across multi-decade periods.

Current Synthesis

The wiki’s current synthesis treats Kondratiev analysis as useful only when it is mechanism-first. E162.康波周期中的AI：新技术总在萧条期爆发，bad times make good people emphasizes drivers, reversals, nested cycles, and the difference between economic-cycle analysis and Technology Installation Cycle. The public-investor correction in EP94 穿越周金涛：人生发财靠康波，守住家底靠少错 is that the long wave can help explain the environment, but it cannot provide exact buy and sell coordinates.

Technology is central but not sufficient. Both sources argue that a new long wave needs more than an invention: production technology, inputs, infrastructure, factories, institutions, user adoption, and a new techno-economic mode have to align. EP94’s steam-engine example shows this as system reorganization, while E162 applies the question to AI as possible sixth-wave infrastructure.

For investing, Kondratiev thinking is a context layer, not a substitute for Portfolio Suitability. It may shape views about AI, commodities, gold, real estate, and macro regimes, but household investors still need capital duration, liquidity, position sizing, and risk controls.

Key Claims

  • Long-wave analysis should study mechanisms and reversals rather than count fixed sixty-year intervals.
  • New long waves require technology, infrastructure, production reorganization, and social adoption to reinforce one another.
  • Weak or depression-like phases can push capital and firms toward new profit sources, connecting the concept to Depression Driven Innovation.
  • AI may be read as a possible sixth-wave core technology while still extending the larger information-technology revolution.
  • Price cycles can lead productivity cycles; real technological change can coexist with bubbles and poor early investor returns.
  • Long-wave judgment may inform Macro Asset Expression, but it is too coarse for precise trading or household timing decisions.
  • Ordinary investors should pair cycle stories with Investment Risk Management and Ordinary Investor Macro Boundary.

Evidence

Counterevidence & Qualifications

  • The framework is historically interpretive and should not be treated as a deterministic calendar.
  • Correctly identifying a long wave does not identify the winning company, asset, or entry price.
  • EP94’s Zhou Jintao dialogue is dramatized reconstruction, so its formulation of the framework is source interpretation rather than verbatim authority.

What Changed

  • Added EP94’s ordinary-investor caution and nested-cycle examples.
  • Made the page schema-compliant and more explicit about technology profit lag and timing misuse.
