조선시대 실학자 반계 유형원이 국가 개혁과 재정비를 주장하며 제시한 정책서다. ‘반계가 수시로 적어 놓은 기록’이라는 의미로, 17세기 중후반의 정치, 경제, 사회 전반에 걸친 개혁안이 체계적으로 정리되어 있다. 유형원은 토지제도 개혁이 법도의 모순으로 어려워진 백성들의 생활을 근본적으로 해결하리라 생각했다. 『반계수록』은 1652년(효종 3) 저술이 시작되어 19년만인 1670년(현종 11)에 완성되었으며, 유형원 사후 100여 년이 지난 1770년(영조 46)에 간행되었다.

This is a policy book authored by Yu Hyeong-won (Pen name Bangye), a scholar of Practical Learning during the Joseon Dynasty, advocating for state reform and reorganization. The title, literally translated as “records written by Bangye from time to time,” systematically organizes reform plans spanning politics, economy, and society in the mid-to-late 17th century. Yu Hyeong-won believed that reforming the land system would fundamentally resolve the challenges face by the people, which had become difficult due to contradictions in the law and custom. It was written in 1652 (the third year of King Hyojong’s reign), completed 19 years later in 1670 (the 11th year of King Hyeonjong’s reign), and published in 1770 (the 46th year of King Yeongjo’s reign), almost 100 years after Yu Hyeong-won’s death.
