一、恩格尔系数恩格尔系数是指食品支出总额占家庭或个人消费支出总额的百分比。1857年,世界著名的德国统计学家恩思特·恩格尔阐明了一个定律:随着家庭和个人收入增加,收入中用于食品方面的支出比例将逐渐减小,这一定律被称为恩格尔定律,反映这一定律的系数被称为恩格尔系数。用公式表示为:恩格尔系数(%)=食品支出总额÷家庭或个人消费支出总额×100%。恩格尔系数过大,必然影响其他消费支出,特别是影响发展资料、享受资料的增加,限制消费层次和 Engel's Coefficient The Engel's Coefficient refers to the percentage of total food expenditure as a share of total household or individual consumption expenditure. In 1857, world renowned German statistician Ernst Engel elucidated the law that as the income of households and individuals increases, the proportion of income spent on food will gradually decrease, a law known as Engel's Law The coefficient that reflects this law is called the Engel's Coefficient. Expressed as: Engel's Coefficient (%) = Total Food Expenditure ÷ Total Household or Personal Consumption Expenditure x 100%. Engel's coefficient is too large, inevitably affect other consumer spending, in particular, affect the development of information, enjoy the increase of data, limit the level of consumption and
