摘要： The prevent invention relates to a biodegradable polymer resin composition which can realize excellent mechanical properties together with biodegradability and has improved molding processability, and a molded article thereof. The biodegradable polymer resin composition may include a polycarbonate-polyester copolymer including a branched repeating unit containing a mediating functional group including a central element and five to ten alkylene or heteroalkylene functional groups bonded to the mediating functional group, an aliphatic polycarbonate repeating unit having a chain structure, and an aromatic polyester repeating unit, and a biodegradable polyester resin having a melt index (measured at 190 °C, 2.16 kg) of 3 g/10 min to 20 g/10 min.
