Pixel driving circuit and driving method thereof, display panel and display device

The invention discloses a pixel driving circuit and a driving method thereof, a display panel and a display device. The pixel driving circuit comprises a driving circuit (1), a compensating circuit (2), a first light-emitting control circuit (3), a first reset circuit (4) and a second reset circuit (5). The driving circuit (1) is connected with a first node (N1), a second node (N2) and a third node (N3) and is used for inputting a driving current to the third node (N3) by utilizing the second node (N2) according to a signal of the first node (N1); the compensation circuit (2) is connected with a first node (N1), a third node (N3) and a first gate driving signal end (G1) and is used for responding to a signal of the first gate driving signal end (G1) so as to conduct the first node (N1) and the third node (N3); the first light-emitting control circuit (3) is connected with a third node (N3), a fourth node (N4) and a first enable signal end (EMl) and is used for responding to a signal of the first enable signal
