The invention relates to the technical field of electric engineering and more specifically relates to a user electricity consumption structure analyzing method. Based on a data mining technology, steady state electricity information of home appliances of a user is acquired through a smart electricity meter. Load elastic time of the user is identified according to different time scales and different external environments, and more accurate user electricity consumption analyzing result is acquired. The analyzing method provided by the invention combines factors including user family conditions,environment factors and the like. The accuracy of the acquired user electricity consumption structure analyzing result is improved and a more scientific data support is provided for planning and execution of schemes such as power grid performance reconstruction and the like.
