Method for producing thermoplastic resin, and compound therefor

A method for producing at least one thermoplastic resin selected from a group consisting of a polycarbonate, polyester and polyester carbonate, comprising a process of melt polycondensation of a dihydroxy compound with a diaryl carbonate and/or a dicarboxylic acid ester in a presence of a transesterification catalyst selected from a compound represented by formula (1) below and/or a compound represented by formula (2) below.
