INTRODUCTION

English translation pending.

CORE DEFINITION

Proposed by the historian Mark Elvin to explain the absence of an indigenous industrial revolution in late imperial China. Agriculture and handicraft production were already highly efficient, population was dense, and labor was cheap, so substituting capital-intensive machinery for human effort offered neither profit nor necessity. The core claim is that an optimized traditional system can block the emergence of a new technological regime. The qualification is that this is a historical explanatory framework to be weighed alongside institutions, knowledge supply, and other conditions.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use Efficiency Trap Check: Ask whether your current method is so cheap and refined that alternatives cannot justify their cost. - Use Trap Contrast: Compare your situation with a low-level equilibrium trap to identify which stagnation mechanism is operating. - Use Shock Search: Look for an external change that raises the cost of the incumbent method enough to unlock substitution.

Anchor fast decisions

Innovation in a mature technology must compete against an incumbent refined over centuries, so a new method starts clumsy and expensive relative to a highly optimized alternative. When labor is abundant and cheap, the savings from mechanization are small, and no one can profitably fund the long development path. The system settles at a high but static level, and only an external shock that raises labor costs or opens new demand breaks the equilibrium.
