A gear selection and shifting actuating mechanism and a gear selection and shifting actuating method, the actuating mechanism comprising a gear shifting motor (1), a first transmission gear (2), second transmission gears (3, 4), gear shifting screws (5, 6), a push block (7), a shift fork, a shift block and a linear driving device. An output shaft of the gear shifting motor (1) is provided thereon with the first transmission gear (2); the first transmission gear (2) is engaged with the second transmission gears (3, 4); the second transmissions gears (3, 4) are fixedly connected to the gear shifting screws (5, 6); the gear shifting screws (5, 6) are in screw thread connection with the push block (7); the push block (7) is provided thereon with a through hole; one end of the shift block is connected to the linear driving device, and the other end is aligned with a groove on the shift fork after inserting into the through hole. The linear driving device that corresponds to a shift position drives the shift block
