Abstract

This study conducted to examine about the income inequality and bi-polarization for forestry household. For this purpose, Gini coefficient and Atkinson index were used to analyze the income inequality for forestry household. Also, DER index were employed to show their income bi-polarization. Before using these methodologies, forestry household income was divided into three parts that was forestry income, non forestry business income and transfer income. And then, income inequality and bi-polarization were analyzed respectively. The result shows that forestry household income inequality was higher than whole household inequality. Apart from transfer income, forestry household income, forestry income and non forestry business income inequality was aggravated. At the same time, these tendency was able to observe the bi-polarization for forestry household income and other income sources.

이 연구는 임가의 소득불평등과 양극화의 추이를 살펴보기 위한 목적으로 수행되었다. 이를 위해 소득불평등도는 지니계수와 엣킨슨 지수를 활용하여 분석하였으며 양극화는 DER 지수를 이용하였다. 그리고 이들 지수들은 임가소득과 함께 이것을 구성하는 하부소득인 임업소득, 겸업소득 그리고 이전소득으로 세분화하여 살펴보았다. 분석결과, 임가의 소득불평등도는 우리나라 전체 가구의 소득불평등도보다 상대적으로 높은 수준으로 분석되었다. 그리고 이전소득을 제외한 임가소득, 임업소득, 겸업소득에 있어서 소득 불평등은 심화되는 것으로 나타났다. 이러한 추세는 양극화에서도 볼 수 있다.
