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.

This study is an empirical analysis on the equity in the delivery of heatlh care under the Korean Medical Insurance Corporation System. The purposes of this study are to find out effects of income on the health care utiliztion and measure the income-related inequity in the distribution of health care. This study was carried out based on the fact that the health insurance program has been organized to achieve the equity objective, "equal treatment for equal needs". Of 41, 828 insured persons who had been diagnosed in the 1993 Health Screening Test and utilifzation data from 1, January 1993 through 31, December 1993 were derived from the Benefit Managment File. Inequity was measured by means of I) share approach, ii) standardization concentration curve approach, iii) inequity index, iv) test for inequity. The major findings were as follows : 1. The expenditure shares of the top two quintile groups exceeded their morbidity shares, whereas the opposite was true of the bottom three quintile groups, Which showed a positive HI$_{LG}$ inequity index, suggesting the presence of some inequity favoring the rich group. 2. Compared with other residential areas, the rural area showed the highest positive HI$_{LG}$ irrespective of need indicatior applied. 3. Standardized expenditure concentration indices adjusted by age, gender and need structure were also found to be positive, and therefore still indicated that there has been inequity favoring the rich after the standardization. 4. The Loglikelihood Ratio (LR) test for the statistical significance of income-related inequity of medical care utilization was carried out using the logistic regression model. The resulting loglikelihood ratio test statistic value was 176, which did exceed the 0.5 percent critical value of the chi-square distribution with 28 degrees of freedom, which is 50.993. Therefore, the null hypothesis of no income-related inequity of medical care utilization was rejected at the 99.5 percent confidence level. 5. The Regression based F-test has been carried out for analyzing the income-related inequity of medical expenditure in terms of age, gender, morbidity indicators as explanary variables. The hypothesis of the absence of income-relate inequity was rejected for all need indicators at the 95% confidence level.nce level.
