摘要： A shift register and a driving method therefor, a gate drive circuit and a display apparatus. The shift register comprises: a first input module (11) for pulling up the potential of a first node under the effect of a signal received by an input end, an output module (13) for pulling up the electric potential of an output end under the effect of the electric potential of the first node, a reset module (15) for pulling down the electric potential of the first node under the effect of a signal received by a reset end, and an output pull-down module (14) for pulling down the electric potential of the output end under the effect of a first clock signal, wherein the first input module (11), the output module (13), the output pull-down module (14) and the reset module (15) are all connected to the first node; and the shift register also comprises a second input module (12) for connecting the input end to the first node under the effect of the first clock signal within working hours of the first input module (11) and the output pull-down module (14). A pull-down node is removed from the shift register, so that the number of transistors can be reduced, which is beneficial for reducing the frame width occupied by a gate drive circuit.
