The present invention provides a terminal-modified copolymer of conjugated diene and vinyl aromatic hydrocarbon and a synthesis method and application thereof. The synthesis method of the terminal-modified copolymer of conjugated diene and vinyl aromatic hydrocarbon includes making a conjugated diene monomer reacts with a vinyl aromatic hydrocarbon monomer in a weight ratio of 2: 1~5: 1 under the presence of an organic alkali metal compound, to generate a copolymer of conjugated diene and vinyl aromatic hydrocarbon having an active terminal; and making the copolymer of conjugated diene and vinyl aromatic hydrocarbon having an active terminal reacts with a compound represented by formula (1), to generate the copolymer of conjugated diene and vinyl aromatic hydrocarbon with terminals modified by the compound represented by formula (1).
