Gini coefficientsとは 意味・読み方・使い方

Gini coefficient is an index to measure the extent of income gaps. In China, Gini coefficient has kept soaring since the 1970s. But the absolute number of such coefficient in China is not significantly different from Gini coefficients in ASEAN4 countries.例文帳に追加

所得格差を表す指標であるジニ係数を見ると、中国におけるジニ係数は、1970年代以降急激に上昇を続けているが、絶対値で見ればASEAN4と大きな差は存在しない。 - 経済産業省

Improvements in the Gini coefficient as a result of income redistribution in Japan were analyzed by comparing the Gini coefficients of equivalent initial income (Note 2) and those of equivalent redistributed income (Note 3). It was found that the effects of income redistribution through tax declined, whereas those through the social security system increased.例文帳に追加

我が国の所得再分配による等価当初所得（注2）から等価再分配所得（注3）へのジニ係数の改善度を見てみると、税を通じた所得再分配効果は減少するとともに、社会保障制度を通じた効果は増加している。 - 厚生労働省

For example, in IMF (2007b)20 report, the factors behind the changes in the Gini coefficients in each region are classified as follows: 1) globalization21, 2) technological advancement22, and 3) other factors. Further, the ratios of their contributions are calculated to analyze the causes of the widening gap in each region.例文帳に追加

例えば、IMF（2007b）20では、各地域のジニ係数を①グローバル化要因21、②技術進歩要因22、③その他要因へと寄与度分解した上で、地域ごとに格差の拡大要因を分析している。 - 経済産業省

The Gini coefficients of the elderly are relatively high compared with other age brackets. Since the population of the elderly, an age group with wider income disparities than other age brackets, is expected to increase, the government should continue to promote measures to secure the economic base of older people, such as a sustainable pension system that provides peace of mind.例文帳に追加

高齢者のジ二係数は、他の年齢階級に比べて高い水準となっており、今後、所得格差が他の年齢階級に比べて高い水準となっている高齢者の増大に伴い、引き続き、持続可能で安心できる年金制度など、高齢期の経済的基盤を確保するための施策を推進していく必要がある。 - 厚生労働省
