所谓“二八定律”,又称之为帕列托定律,是19世纪末20世纪初意大利经济学家帕列托(Vilfredo pareto)发明的。该定律认为,在任何一组东西中,最重要的只占其中一小部分约20%,其余80%尽管是多数却是次要的。经过百年历史岁月的考证,该定律被越来越多的人们所接受、认同,其涵义也不? The so-called “twenty-eight law,” also known as the Pareto law, was invented by the Italian economist Vilfredo pareto in the late 19th and early 20th centuries. The law holds that in any group of things, the most important is only about 20% of a small part of it, while the remaining 80% is minor, though mostly. After a hundred years of history research, the law is accepted by more and more people, identity, its meaning is not?
