The invention discloses a novel phenoxy ester coordinated transition metal organic complex, an olefin polymerization catalytic system comprising the same and an application of the catalytic system. The catalytic system comprises (A) a transition metal organic complex with a general formula (I) and (B) main group metal organic compounds, organic aluminoxane and ionic compounds which can be ionized. The transition metal organic complex is shown in the general formula (I), wherein in the formula, M is one or more of transition metal elements in an IV, V or VIII subgroup in the periodic table of elements, m is an integer from 1 to 3, n is a number satisfying the M valence state, X is halogen, alkoxy and the like, R1 is C1-20 alkyl or C6-20 aryl or substituted aryl, and R2-R5 are the same or different and are selected from hydrogen atoms, halogen atoms, alkyl, silyl and the like. The catalytic system has the advantages of high catalytic activity, good thermal stability, strong copolymerization capability and the l
