Kaizhong System

CORE DEFINITION
The Kaizhong system was introduced in the early Ming to supply frontier garrisons. Merchants who transported or delivered grain to border armies received salt certificates, which entitled them to buy salt from the state monopoly and sell it in designated regions. The core proposition is that granting access to a highly profitable monopoly motivates private actors to solve a public logistics problem far more cheaply than direct state provision. The key qualification is that the scheme depended on the salt monopoly retaining its value; when the state later accepted silver payments instead of grain, the incentive to move food to the frontier disappeared and border reserves declined.
SCAFFOLDING EFFECT
Reduce cognitive load
- Open A Monopoly: grant privileged access to a scarce resource as payment for hard work. - Outsource The Logistics: let partners profit from solving a problem you cannot serve cheaply. - Guard The Incentive: check that the privileged resource keeps enough value to sustain the behaviour.
Anchor fast decisions
Moving grain to a distant frontier costs more than the grain itself, so direct state transport is expensive and corruptible. Salt carried a monopoly margin large enough to cover that transport cost and still leave a profit. Merchants therefore built supply routes, and in some cases farms, at their own expense, because the licence converted their effort directly into a valuable tradable right.
