A scooter driving structure includes a step member pivotally coupled to a scooter platform and swingable up and down, a first driving module installed at a position corresponding to the step member and comprising a driving rod, a guide wheel, a first driving wheel, a first driving belt and a position restoring element, and at least one second driving module installed between a pivotal axle of the first driving wheel and an axle center of a rear wheel and comprising a second driving wheel, a second driven wheel and a second driving belt. The step member is pedaled to move the driving rod of the first driving module and drive the first driving belt to rotate the first driving wheel, and the coaxial second driving wheel of the second driving module drives the second driven wheel and the rear wheel to rotate through the second driving belt, so as to achieve a dual drive effect of driving a scooter to move.
