The invention relates to a method and a system for testing the anti-counterfeit card attack function of a fee control electric energy meter. The method comprises the following steps: obtaining the response execution information of the double-mode feed control electric energy meter when different error parameter user cards are inserted respectively, and judging whether the obtained response execution information is matched with corresponding first preset information; obtaining the response execution information of the double-mode feed control electric energy meter when a correct parameter user card is inserted, and judging whether the obtained response execution information is matched with second preset information; if the judgment result in any step is detected to be not matched, judging that the anti-counterfeit card attack function of the double-mode fee control electric energy meter is unqualified; if the judgment results in all steps are detected to be matched respectively, judging that the anti-counterfeit card attack function of the double-mode fee control electric energy meter is qualified. Through the method and the system, the anti-counterfeit card attack function of the double-mode fee control electric energy meter can be detected comprehensively and accurately.
