The invention discloses a power frequency electric field test comparison method and system, and the method comprises the steps: carrying out the measurement of a plurality of times at a preset position after a comparison site is determined, and judging the stability of a standard source according to an obtained measurement value; when it is determined that the stability of the standard source is stable, instruments to be measured in different laboratories are used for measurement, and final measurement values corresponding to all the laboratories are obtained; determining a standard value according to the final measurement value corresponding to each laboratory; and determining a relative difference and an evaluation result corresponding to each laboratory according to the standard value, and selecting a target laboratory according to the relative difference and/or the evaluation result. According to the invention, through comparison of test data between laboratories, the electromagnetic environment detection
