劳动生产力上最大的增进，以及运用劳动时所表现的更大的熟练、技巧和判断力，似乎都是分工的结果。（The greatest improvement in the productive powers of labour, and the greater part of the skill, dexterity, and judgment with which it is any where directed, or applied, seem to have been the effects of the division of labour.）——[英]亚当·斯密：《国民财富的性质和原因的研究》（上卷），郭大力、王亚南译，商务印书馆，1972年，第1页；Adam Smith, An Inquiry into the Nature and Causes of the Wealth of Nations, Book I, Chapter I, 1776.
