The invention relates to a catalyst for preparing vinyl acetate by an ethylene method, and mainly solves the problems of low activity and selectivity of a catalyst in the prior art. The catalyst for preparing the vinyl acetate by the ethylene method comprises a carrier, an active component and a co-catalyst, wherein the carrier is prepared from SiO2, Al2O3 or mixture of the SiO2 and the Al2O3, the co-catalyst is alkali metal acetate, and the active component comprises metal Pd, metal Au and at least one of platinum group metal and IVA. The problems are effectively solved, and the catalyst can be used for industrial production of the vinyl acetate.
