The present invention belongs to the technical field of OLEDs, and particularly relates to a silver-based alloy, a preparation method therefor, a silver alloy composite thin film and the use thereof. The silver-based alloy provided in the present invention comprises silver and doping elements, wherein the doping elements account for 0.01-0.8% by mass of the silver-based alloy, and the doping elements comprise zinc. The silver-based alloy in the present invention not only has excellent electrical conductivity and thermal conductivity of silver, but also has a resistance to zinc corrosion, so that the silver-based alloy has a higher corrosion resistance under a high-temperature condition, which ensures the formation of island-shaped structures of the silver-based alloy are reduced under the high-temperature condition, and the silver-based alloy still has a very high reflectivity. The silver alloy composite thin film provided in the present invention comprises a silver-based alloy thin film layer, and indium tin
