家园 exactly.

structural est. is built on some theoretical equilibrium established beforehand. The equilibrium may be too complicated to solve.

Reduced form est. doesn't need theoretical structure, just like all Xs are exogenous in reduced-form equation. If reduced-from est. hits endogenous variable, you don't go back to model the stucture of target variable and endogenous variable, but to use techniques to correct the bias.
