By superimposing the Kuznets cycle (real estate / long), the Juglar cycle (manufacturing capex and exports / medium), and the inventory cycle (traditional manufacturing prices / short), one examines the economy through their combined lens: when all three cycles are moving upward in unison, the economy is strong; when all three are descending together, the economy is weak; when a mixed state appears (two declining plus one rising, etc.), the situation must be identified as an impure state. The Kondratiev wave (approximately 45–60 years) poses falsifiability challenges and is used only as a reference backdrop, not as the primary analytical framework. The ultimate purpose of the superposition is to establish the economy’s fundamental orientation — in other words, to locate the “sense of position.”
The Framework As It Stands
This section is compiled based on the research manuscript: it preserves the original framework’s structure, terminology, and key expressions, including editorial bridges and external factual annotations; diagrams are drawn by the compiler following the original text’s structure.
The Boundaries of the Kondratiev Wave: Why It Is Used Only as Reference
The Kondratiev wave is an approximately 45–60 year long cycle driven by technological revolutions or shifts in the global order. However, its delineation is subject to interpretation — seven or eight mainstream versions exist, producing widely divergent conclusions. The same historical data point can be interpreted as either a downswing or an upswing.
The framework’s ruling: the Kondratiev wave presents a falsifiability challenge and is not recommended as the primary analytical framework; it may only serve as a reference backdrop for judging macro trends.
Three-Cycle Superposition: The Primary Analytical Framework
Macro-economic analysis can examine the economy using a framework that superimposes the Kuznets cycle, the Juglar cycle, and the inventory cycle.
Division of economic meaning across the three cycles:
| Cycle | Duration (empirical) | Core Driver |
|---|---|---|
| Kuznets | Approximately 15–25 years (long) | Real estate cycle |
| Juglar | Approximately 8–10 years (medium) | Manufacturing capital expenditure and exports |
| Inventory | Approximately 2–3 years (short) | Traditional manufacturing price fluctuations |
Reading the combined direction when superimposing:
- All three cycles moving upward in unison → economy is strong
- All three cycles declining together → economy is weak
- Mixed state (two declining plus one rising, etc.) → impure state; the dominant driver must be identified; one cannot simply read strength or weakness
Position-Sense Framework is the landing point of this superposition framework — the essential purpose of superposition is to “locate the sense of position,” just as determining whether the dark of night is midnight or 4:30 a.m.; both fall within night, but the implications are entirely different.
Three Historical Cases (Historical review as of the December 2018 course, not current conditions)
① 2003–2004: Three-cycle resonance upward The Kuznets (real estate cycle), Juglar, and inventory cycles all rose → three-cycle resonance upward; corresponding asset performance: strong equity markets, rising interest rates, bond bear market.
② 2014–2016: Three cycles declining together Kuznets peaked and declined, Juglar declined, inventory declined → weak economy; corresponding asset performance: poor performance of risk assets, falling interest rates.
③ 2016 Q3 – 2017 Q2: Mixed state (impure) Kuznets and inventory cycles declining, but Juglar rising → moderate economic improvement, not a pure state with all three cycles moving in the same direction.
Timing caveat: the three cases represent a historical review as of the time of the course (December 2018), used as framework illustrations, not current conditions; judging “the current three-cycle orientation” requires taking the current data for each cycle.
Reasoning Chain
Kondratiev wave (45–60 year long cycle) → falsifiability challenge → reference only, not primary framework
┊ (reference backdrop, not primary axis)
Primary framework: Kuznets (real estate / long) + Juglar (manufacturing capex-exports / medium) + inventory (prices / short) — three cycles superimposed
↓ read combined direction
All three moving upward → strong economy (2003–04: strong equities / rising rates / bond bear)
All three declining → weak economy (2014–16: weak risk assets / falling rates)
Mixed state (two declining plus one rising, etc.) → impure state, must identify driver (2016 Q3–17 Q2: moderate improvement)
↓ synthesis
Establishing the economy's fundamental orientation = locating the sense of position (midnight vs. 4:30 a.m.)

Bridge Layer
The most frequent misuse of this framework: incorporating the Kondratiev wave into the primary inference chain and using “currently in a Kondratiev downswing” to directly derive “China’s economy must remain depressed for an extended period,” skipping the on-the-ground data check for the Kuznets/Juglar/inventory cycles. The problem with the Kondratiev wave is not that “it is too long and impractical,” but that it fundamentally poses a falsifiability challenge — seven or eight mainstream delineations arrive at opposite directional conclusions for the same historical moment. This means that conclusions using the Kondratiev wave as the first inferential premise cannot be refuted, and thus lose methodological meaning.
Proprietary incremental assertion: the framework displays its most essential judgmental value in the 2016 Q3–2017 Q2 mixed-state case — when the three cycles point in different directions, the adjudication of “moderate economic improvement” requires identifying which cycle is the dominant driver (Juglar: manufacturing capex and exports rising), rather than making a simple binary strong/weak judgment. Historically, pure states where all three cycles align (whether upward or downward) are easy to read; mixed states are the real testing ground for an analyst’s “sense of position” capability. The 2014–16 three-cycle declining period — associated with falling rates and compressed risk assets — and the 2016 Q3–2017 Q2 mixed-state moderate improvement are separated by barely half a year; without the superposition framework, the two cannot be distinguished.
The soul_anchor’s meaning here: locating the sense of position is itself a method that requires long-termism to sustain — the cost of misreading a single quarter’s data is manageable; the real compounding return lies in continuously calibrating one’s macro orientation judgment with the three-cycle framework, seeing the signs before cycle turning points, rather than only being able to articulate the logic in hindsight.
