  The present invention provides an improved method for continuously producing a high-molecular-weight polycarbonate resin by carrying out a linking and highly-polymerizing reaction of an aromatic polycarbonate prepolymer with an aliphatic diol compound wherein the retention time of the reaction mixture in the linking and highly-polymerizing reactor is shortened to achieve excellent performance. The process comprises a process (A) for producing an aromatic polycarbonate prepolymer by polycondensation reaction of an aromatic dihydroxy compound with diester carbonate and a process(B) for conducting linking and highly-polymerizing reaction of the aromatic polycarbonate prepolymer with an aliphatic diol compound in the linking and highly-polymerizing reactor, wherein the aromatic polycarbonate prepolymer produced by the process (A) is fed continuously to the linking and highly-polymerizing reactor, while the aliphatic diol compound is fed continuously thereto under reduced pressure of 10 torr or less to carry out the reaction.
