  The present disclosure provides an olefin polymerization catalyst and a combined catalyst containing the same. The catalyst comprises a reaction product of a magnesium dialkoxide, a titanium compound, an electron donor compound A and an electron donor compound B, wherein the electron donor compound A is a sulfonyl compound represented by general formula I, X is a disubstituted or unsubstituted group 14 element atom, a monosubstituted or unsubstituted group 15 element atom or group 16 element atom, and the substituent is a monocyclic, polycyclic or heteroatom-containing cyclic group or an aliphatic chain; R 1 and R 2 are respectively hydrogen atom, halogen atom, substituted or unsubstituted alkyl, cycloalkyl, aryl, aralkyl, alkylaryl or heteroatom-containing cyclic group. The combined catalyst comprises the catalyst and an organoaluminium compound and can comprise an organosilicon compound. The catalyst has a high activity and a good stereospecificity, and polymers prepared therefrom have a good particle morphology and little fine powder.
