A process for manufacturing a dual-layer composite floor and a product thereof. The dual-layer composite floor comprises a wooden or bamboo-made surface plate and a fiberboard substrate, and further comprises a balancing layer glued on the back side of the substrate. The balancing layer is a polyethylene film and has a thickness of 0.5-5 mm. The surface plate has a thickness of 0.6-6 mm. The process for manufacturing a dual-layer composite floor comprises a hot-pressing step of hot-pressing the fiberboard substrate on the surface plate, and a step of cold-pressing the balancing layer on the back side of the pressed substrate. In the hot-pressing step, the treatment temperature is 60-130°C, the pressure is 1-3 MPa, and the pressure-holding time is 5-7 min; in the cold-pressing step, the treatment pressure is 1-3 MPa and the pressure-holding time is 20-40 min.
