The invention discloses a catalyst for production of methyl acetate through carbonylation of dimethyl ether. The catalyst is characterized by containing an acidic EMT molecular sieve and a mesoporous oxide adhesive, wherein the weight percent of the acidic EMT molecular sieve in the catalyst is 30-95%. By using the EMT molecular sieve as an active component and the mesoporous oxide as the adhesive, the methyl acetate selectivity and the catalyst stability are greatly improved.
