A high-flow polycarbonate resin of the present invention contains 1-30 mole% of a phosphorus-free chain cutting agent and 5-30 mole% of hydroxyl radical. The high-flow polycarbonate resin is manufactured by melt-polymerization and has economic efficiency using reproduced polycarbonate with excellent productivity. The high-flow polycarbonate resin also has excellent flowability by applying the phosphorus-free chain cutting agent. In addition, the resin has strong heat-resistance thereby preventing molding defects such as silver marks and has excellent transparency.
