The invention provides monovinyl arene-conjugated diene copolymer composition as well as a preparation method and an application thereof. The monovinyl arene-conjugated diene copolymer composition comprises [(SB)1-(SB)2]mM1, [(SB)1-(SB)2]nM2 and (SB)1-(SB)2, wherein S represents a monovinyl arene structure unit, B represents a conjugated diene structure unit, SB represents a copolymerization chain segment of monovinyl arene and conjugated diene, the content of the monovinyl arene structure unit in the (SB)1 chain segment is different from that of the monovinyl arene structure unit in the (SB)2 chain segment, M1 and M2 are different coupling agent residues, m represents 3 or 4, n represents 2 or 3, and m and n are different. Rubber containing the monovinyl arene-conjugated diene copolymer composition not only has low rolling resistance and high wet-skid resistance properties, has excellent mechanical property and simultaneously has a satisfactory processing property.
