This research aims to identify regional inequitable development through the analysis of facilities distribution pattern. This study describes the concepts underlying the application of the Gini's coefficient and decomposition method to measure the regional inequitable development in Sun-chang County, Jeonbuk Province, Korea. We used the facility data surveyed for three years, from 2010 to 2012 for facility distribution pattern that RDA surveyed. These data have been serviced on the web. The Lorenz Curve presents a graphical view of the inequitable facility distribution and the Gini's Coefficients quantifies the distribution pattern. And furthermore, Gini Decomposition represents intra regional inequalities. These applied techniques can describe how the local development affects other district and change regional inequalities.

This study employed the Gini coefficient decomposition analysis to classify and examine fishery household income inequality according to income sources. The raw data from the Fisheries Economic Survey by the National Statistical Office were used for the analysis after equalization according to the recommended method of the OECD. In particular, the Gini coefficient was decomposed by classifying with and without public subsidies, and the contribution, correlation, and marginal effect by income source were presented.As a result of the analysis, the inequality of fishing income and non-fishing income of fishermen was worsening, and the inequality of transfer income was continuously easing. Among them, fisheries subsidies have been analyzed to have the greatest contribution to the Gini coefficient of gross income and the highest relative marginal effect, although distribution inequality has been alleviated. On the other hand, other subsidies, including public pensions, were found to have the opposite contribution, correlation, and marginal effect to fisheries subsidies. The results of this analysis showed that even within public subsidies, the contribution to income redistribution might differ depending on the nature of the subsidy. In addition, in the case of other public subsidies, it can be seen that the transition from selective welfare to universal welfare occurs.

This study analyzed the distribution of forest income and other variable sources of rural household income and considered their importance for the reduction of income inequality and poverty. We employed Gini decomposition to measure the contribution of forest income and other sources of income to income equality and assess whether they were inequality-increasing or inequality-decreasing in the 14 villages. The forest income Gini correlation with total income was very high, $R_k=0.6960$, and the forest income share of total rural household income was 35% ($S_k=0.3570$). If the income earned from forest activities was removed, the Gini index would increase by 10.3%. Thus, if people could not access forest resources because of vast deforestation, perhaps from the limitations of government-managed forestry, unplanned clearing of forest land for agriculture or the granting of ELCs, there would be an increase in income inequality and poverty among rural households. The findings suggest that policy makers should look beyond agriculture for rural development, as forest resources provide meaningful subsistence income and perhaps contribute to both preventing and reducing poverty and inequality in rural communities. The study found that non-farm activities were inequality-increasing sources of income. The share of non-farm income to the total rural household income was $S_k=0.1290$ and the Gini index of non-farm income was very high, $G_k=0.8780$, compared with forest and farm income. This disagrees with other studies which have reported that non-farm income was inequality-decreasing for the rural poor.

This study examines trends in the overall income inequality of fishery household from 2003 to 2012 with the panel data of the Fishery Household Economy Survey. To investigate the potential determinants of income inequality, we decomposes the Gini coefficients into five income sources, fishery income, non-fishery income(non-fishery business income, non-business income), transfer income, irregular income and calculate the impact of each income sources on total income inequality. An evident trend toward increasing inequality of household income was found. Also, we find rising fishery income and non-fishery income play important role in the rapid increase of income inequality. Only transfer income appear to reduce total income inequality.

Most of countries are trying to increase the supply of renewable energy as the substitute of the fossil energy for reducing greenhouse gas emissions. However, renewable energy sources account for only about 3.86% of the total Korea primary energy supply. To increase the rate of renewable energy in Korea's energy consumption, various policies for expanding the use of renewable energy should be applied. Also these policies should be consider renewable energy resources distribution and regional inequality. In this study, the potentials of photovoltaic, wind power and bioenergy from rice straw, livestock waste and food waste are calculated and the distribution characteristic and regional inequalities are analyzed using Gini's coefficient and Gini decomposition method. As the results, technical potentials of photovoltaic and wind power of city region(Gu) has more potential rate than theoretical potentials. Livestock waste has the most unequal distribution (Gini's coefficient: 0.617) among renewable resources.

불평등 지수의 분해란 사회 전체의 불평등을, 이에 영향을 미치는 개별원천들로 분해하여, 그 원인을 밝히고자 하는 것이다. 기존에는 개별요인들이 전체 불평등에서 정량적으로 차지하는 절대적 기여도에만 관심을 가져왔다. 그러나 불평등 완화를 위한 정책을 효과적으로 수행하기 위해서는, 개별원천들이 가지고 있는 한계적인 불평등 효과를 아는 것이 더 중요할 것으로 생각된다. 본 연구에서는 이를 위하여 대표적인 불평등 지수라 할 수 있는 지니계수를 소득원천별 혹은 사회복지 프로그램별로 분해하고, 각각의 Gini Income Elasticity(GIE)를 계산하였다. 분석결과에 따르면, '상용근로자 소득'과 '고용주 및 자영자 소득'의 GIE가 각각 1.205와 1.867로, 이들의 증가는 사회 전체의 불평등을 악화시킬 수 있는 소득원천들로 분류되었다. 이러한 GIE를 이용한 분석방법은 소득원천 혹은 사회복지 프로그램들의 불평등 효과를 분석하는데 있어서 하나의 유용한 방법의 될 수 있을 것이다.

이 글에서는 2000년대 중반 이후 한국의 임금불평등을 지니계수의 변화와 이를 초래한 요인들의 기여도를 분석하였다. 자료와 임금 지표에 따라 추세가 달라지지만, 주당 35시간 미만 일하는 파트타임의 증가로 전체근로자 임금총액의 지니계수는 증가하는 추세를 보여주는 반면, 시간당임금 지니계수와 풀타임근로자의 임금총액 지니계수는 하락하는 추세를 나타냈다. 파트타임 증가가 임금총액 기준의 불평등은 높였지만, 파트타임의 시간당임금 증가는 시간당임금 기준의 불평등을 낮추었다. 풀타임 노동자만을 대상으로, 지니계수 감소 요인을 분해한 결과, 불평등 감소에 절대적으로 기여가 큰 요인은 근속, 경력, 직종 등의 변수였고, 고용형태 변수는 불평등 감소에 미미하게 기여하는 것으로, 사업체 규모 변수는 불평등을 오히려 높이는 것으로 나타났다. 업종이나 연령, 교육 등의 변수는 불평등 변화에 유의미한 크기의 기여를 하지 못한 것으로 분석되었다. 여기에는 장기근속과 관리전문직종에 대한 임금프리미엄의 감소와 대규모사업체의 임금프리미엄 증가 등이 작용한 것으로 분석되었다.

This study investigates inequality of the private educational expenditure using the Family Expenditure Survey of 1990, 1996, 1998, and 2000. The major results are: first, inequality of the private educational expenditure has been relived between 1990 and 2000; second, despite decrease in household income right after the Korean economic crisis, the private educational expenditure has been increased in the households having middle and high school students; third, the gaps in the private educational expenditure between income groups are mainly due to the differences in the spending levels of the private education rather than differences in the percentages of households who spend any in the private education; fourth, in 2000, the gini coefficient of the private educational expenditure among households having elementary school student is 0.4832, and 0.6468 among households having middle and high school students; fifth, 30% of the households having middle and high school students who show the highest level of the private educational expenditure occupy 80% of the total private educational expenditure made by the whole households.

This paper studied balanced regional development focused on employment in Korea, by analyzing regional disparity between regional and industrial employment. A Gini-coefficient decomposition method and Panel Granger causality test were conducted, using raw data of the Census on Establishments reported by the Statistics Korea. The regional and industrial disparity of employment, based on the Gini-coefficient decomposition method, have increased by year. However, the growth rates of disparity are on the decrease. Most of employment disparity occurred from regional disparity between SMA (Seoul Metropolitan Area) and Non-SMA. Industrial disparity are occurred mainly by the service industry. The amount of contribution to the whole disparity of inter/intra regional employment was differed by each industrial sector. Also the causal relationship between employment growth of manufacture and that of service industry was analyzed by Panel Granger causality test. In national level, the employment growth in manufacture industry has conduced that in service industry. On the other hand, in the Non-SMA, only the employment growth in manufacture industry has augmented that in service industry. In conclusion, to reduce employment disparity, the strategy for balanced regional development should be emphasized. Different strategies are needed across regions and industries. Basically creating new job in the Non-SMA is inevitable. In view of stable employment, manufacture industry is more desirable rather than service industry.

이 연구는 소득과 불평등 간의 관계에 대한 다양한 논의가 진행되고 있는 가운데 임가의 소득과 소득불평등 간의 관계를 알아보기 위해 동태적 접근법을 통해 그 관계를 알아보고자 하는데 있다. 이를 위해 단위근 검정과 공적분 검정을 실시한 후 불안정한 시계열 자료를 안정적인 시계열 자료로 변환시킨 후 VAR 모형을 추정하였고 이를 바탕으로 충격반응, 분산분해 분석을 실시하였다. 분석결과, 임가 소득의 영향이 지니계수에 의한 영향에 비해 상대적으로 큰 것으로 나타났으며 임가 소득의 충격이 자체 소득을 증가시키는 방향으로 작용할 뿐만 아니라 지니계수를 감소시키는 영향을 주는 것으로 나타났다. 또한 지니계수의 충격은 임가 소득을 감소시키는 방향으로 영향을 미치며 소득불평등을 더욱 심화시키는 것을 보여주고 있다. 따라서 임가 소득불평등을 완화시키기 위해서는 소득분배 정책보다는 소득성장 정책이 보다 효과적일 수 있을 것이라는 결론을 얻을 수 있었다.
