Abstract

This paper examines trends of the income inequality index and the income quintile share ratios, using the Household Survey released by Statistics Korea. We discuss their respective effects on total income inequality and the income disparity, as a contribution concept defined in this paper for 1990-2014 periods. Main findings are as follows. First, the contribution of 2-person families to total inequality with the current income or the disposable income becomes bigger, and growth rates have been above 10% since 2003. Second, the contribution of 1-person families to income inequality is greater than that of 2-person families. Policy implication is such that the government had better investigate the 1 or 2 person families in-depth to set up the policy measures for weakening the income inequality.

본 논문은 1990-2014년 "가계동향조사" 자료로써 소득불평등도 추이를 살피고, 1인 및 2인 가구들이 전체 소득불평등도와 소득격차에 미치는 효과를 기여도 개념으로 실증분석 하였다. 주요 분석결과를 기여도 중심으로 요약하면 다음과 같다. 첫째, 경상소득 및 가처분소득 기준으로 2인 가구의 소득불평등도에 대한 기여도는 시간이 지나면서 증가추세를 보이고 있으며, 2003년 이후부터 그 수준이 10%를 초과하는 것으로 나타났다. 1인 가구의 소득 불평등도에 대한 기여도는 2인 가구에 비해 더 컸다. 둘째, 1-2인 가구의 소득5분위 배율에 대한 기여도는 2006년 이후 증가하며, 2인 가구에 비해 1인 가구의 기여도가 더 컸다. 이상에서 소득불평등도 완화와 소득격차 확대 해소를 위해서 1-2인 가구에 대한 심층적인 조사와 분석을 수행하고, 그 결과에 기초한 정책방안들을 제시할 필요가 있다는 시사점을 도출할 수 있었다.
