A method for producing a modified conjugated diene-based polymer, comprising: a polymerization step of polymerizing a conjugated diene compound or copolymerizing a conjugated diene compound with an aromatic vinyl compound using an alkali metal compound or an alkaline earth metal compound as a polymerisation initiator to obtain a conjugated diene-based polymer having a reactive end, and a modifying step of reacting a compound having a specific structure with the reactive end of the conjugated diene-based polymer.",
