The invention provides an evaluation method for self-adaptive load type distribution transformer operating economy. The evaluation method comprises the following steps: calculating the yearly compressive loss of the self-adaptive load type distribution transformer; calculating the yearly compressive loss of a common distribution transformer; calculating the difference value between the yearly compressive loss of the common distribution transformer and the yearly compressive loss of the self-adaptive load type distribution transformer; calculating the investment difference value between the purchase price of the self-adaptive load type distribution transformer and the purchase price of the common distribution transformer; and evaluating the operating economy of the self-adaptive load type distribution transformer. The evaluation method, by performing statistics and analysis on the yearly load rate actual distribution condition of the distribution transformer, accurately evaluates the operating economy condition in adopting the self-adaptive load type distribution transformer based on a unit distribution area, so that the applicable range can be determined, blindness in selection is avoided, the functional value of the self-adaptive load type distribution transformer is actually utilized, and a scientific judgment criterion for selection of the distribution transformers is proposed for power supply enterprises.
