恩格尔系数≒ngé'ěr xìshù统计学中指家庭用于食品的支出与家庭消费总支出的比值。其数值越小说明生活越富裕,数值越大说明生活水平越低。因德国经济学家和统计学家恩格尔(Ernst Engel)最先提出而得名。{Engel coef-ficient; (in statistics) ratio of expenses on food against the total a family spends on consumption. The smaller the figure, the wealthier the family, and vice versa; named after German economist and statistician Ernst Engel, who first devised it.} |
