The invention relates to the field of electric energy meters, in particular to a data local transmission method for an electric energy meter, and the electric energy meter. The electric energy meter comprises a micro-processing chip; and the micro-processing chip is electrically connected with an internal memory, an interface connected with an external memory, and a key. The method comprises the steps that a configuration file is established in the external memory, wherein the configuration file is configured with a data requirement; the external memory is connected with the micro-processing chip through the interface connected with the external memory; a user triggers the key; the micro-processing chip reads the data requirement of the configuration file; and the micro-processing chip uploads data stored in the internal memory to the external memory according to the data requirement, or downloads data stored in the external memory to the internal memory.
