본 연구의 목적은 쌀소득보전직불제가 농가소득 변동성에 미친 영향을 분석하는 것이다. 분석에는 2013~2017년 '농가경제조사'와 '농축산물 생산비 조사'에서 추출한 375개 농가 패널 자료가 사용되었다. 분석방법은 변동계수 비교, 분산분해분석, 그리고 로버스터 회귀모형을 이용하였다. 직불금 여부에 따른 농가소득 변동성 차이를 분석한 결과, 직불금은 농가소득의 변동성을 유의하게 감소시킨 것으로 확인되었다. 분산분해분석을 통해 농업소득의 분산은 총수입(변동직불금 제외)의 분산으로 75%, 농업비용의 분산으로 19.8%, 변동직불금의 분산으로 6.0% 설명될 수 있음을 확인하였다. 회귀분석 결과 쌀재배면적이 클수록 소득안정화 효과는 커지는 것으로 나타났다.
The objective of the this study is to find a way to increase fm household income through investigating their computer applications. We utilized the 2000 Korea Agricultural Survey data and applied a Heckman Selection Model to correct a selection bias. The present study found the following results. First, determinant of income among fm households by the level of computer applications has significant statistical differences based on their choices of computer applications. Accordingly, the application of general linear regression about fm income without adjusting these choices may cause statistical fallacy. Second, it has been reported that increasing the member of household is not directly related to increasing the fm income. In case of computer-own farm household, the effect of decrease in income according to increasing in age was predicted. However, in the fm household not possessing computer, it shows negative relationship. It shows that an agricultural career of farm owner and educational attainment of all farm household members have positive relationship regardless of computer possession. The income of the farm household those main field is not agriculture is also found to be lower than that of farm household whose major earnings come from agriculture.
