The invention provides a power driving system and a vehicle. The power driving system comprises a power source, a planet row speed reducing mechanism and a first planet gear transmission mechanism. A power input element of the planet row speed reducing mechanism is connected with an output shaft of the power source. A first inner gear ring of the first planetary gear transmission mechanism is connected with a power output element of the planet row speed reduction mechanism, and the rotating speed of the power output element is smaller than that of the power input element. The first sun gear is arranged in the center of the first inner gear ring and serves as a first output end. The outer planet gear is in meshed connection with the first inner gear ring, the inner planet gear is in meshed connection with the first sun gear, and the first planet carrier serves as a second output end. According to the power driving system, through cooperation of the planet row speed reduction mechanism and the first planet gear transmission mechanism, the speed change function and the differential function can be achieved at the same time, and the power driving system has the advantages of being simple in structure, small in size, light in weight and the like.
