Provided is a polyester thermoplastic resin composition, which is superior in mechanical strength and impact resistance and is capable of stably forming large-size blow-molded products owing to high melt strength. The polyester thermoplastic resin composition comprises (A) 30-70 parts by weight of a polyester resin, (B) 30-60 parts by weight of a polycarbonate resin, (C) 10-40 parts by weight of a styrenic copolymer, and (D) 0.5-2 parts by weight, based on 100 parts by weight of the base resins (A)+(B)+(C), of an acrylic-modified polytetrafluoroethylene. The polycarbonate resin has a weight average molecular weight of 10,000-200,000.
