Abstract: The present disclosure provides a shift control method for a hybrid vehicle with a DCT that includes: a shifting state-determining step in which a controller determines whether an inertia phase of power-off down-shift is entered; a motor torque-adjusting step that request to reduce regenerative braking torque of a motor as much as a predetermined requested reduction amount, when the controller determines that the inertia phase has been entered in the shifting state-determining step; and a clutch torque-reducing step that ends the motor torque-adjusting step and reduces torque of an engagement clutch, when the requested reduction amount of the regenerative braking torque of the motor is less than zero while the controller performs the motor torque-adjusting step.
