A method for producing a modified conjugated diene polymer, comprises polymerizing (i) a monomer comprising a conjugated diene compound, or (ii) a monomer comprising a conjugated diene compound and an aromatic vinyl compound, in the presence of: at least one compound selected from the group consisting of formulae (1) and (2), and an alkali metal compound or an alkaline earth metal compound. A 1 is a functional group which has a hydrocarbylsilyl group in which three hydrogen atoms in a —SiH 3 structure are each substituted by a hydrocarbyl group; has at least one atom selected from the group consisting of N, P and S; and has no active hydrogen and is bound to R 1 by any one atom of the N, P and S. R 1 and R 2 are hydrocarbylene groups. |
