Provided is a recovery and tracing method for missing data of daily electric quantity. The method comprises the following steps: acquiring user information and electric energy meter information and monthly electric quantity data thereof; obtaining daily electric quantity data of each user according to a daily electric quantity rule; examining daily electric quantity in each month and finding out the daily electric quantity which needs to be recovered in each month; adopting two multiple-imputation models based on different algorithms to recover the daily electric quantity which needs to be recovered in each month and obtaining a recovery data set; and comparing obtained daily monthly electric quantities of users with monthly electric quantities corresponding to the recovery data set and taking the recovery data set with the minimal deviation ratio as a best result set. The recovery and tracing method for missing data of daily electric quantity has the following advantages: by recovering missing value of daily
