A poly(lactic acid-b-3-hydroxypropionic acid) block copolymer according to the present invention has excellent mechanical properties by simultaneously employing a lactide optical isomer-derived repeating unit and a poly(3-hydroxypropionic acid) repeating unit, and thus can be applied to broader fields. 본 발명에 따른 폴리(락트산-b-3-하이드록시프로피온산) 블록 공중합체는, 락타이드 광학 이성질체 유래 반복단위와 폴리(3-하이드록시프로피온산) 반복단위를 동시에 도입함으로써, 블록 공중합체의 기계적 물성이 우수하여 응용 분야를 확대할 수 있다는 특징이 있다.
