The invention relates to the technical field of electric driving, in particular to a dual-motor driving system and an electric power-assisted carrier. The dual-motor driving system comprises a middle shaft, a first transmission wheel, a planetary gear set, a first motor, a second motor, a second transmission wheel and a third transmission wheel; the planetary gear set comprises a sun gear, a planetary gear mechanism and a gear ring, and the planetary gear mechanism is meshed with inner teeth of the sun gear and the gear ring; the planet wheel mechanism is arranged on the planet shaft in a sleeving mode, and the planet shaft is fixedly arranged on the second transmission wheel so that the second transmission wheel can form a planet carrier. The first transmission wheel is fixedly arranged on the middle shaft and is in transmission connection with the gear ring; a first motor shaft of the first motor is in transmission connection with the gear ring; a second motor shaft of the second motor is connected with the sun gear to drive the sun gear to rotate; the second transmission wheel is in transmission connection with the third transmission wheel so as to output power to wheels. In this way, stepless speed change adjustment can be achieved more simply and efficiently.
