那我就一句一句翻吧.
This original concept of complementarities was first introduced by Edgeworth (1881)
这个叫”互补性“的初期思想是由埃奇沃斯(1881)提出的,
in which Edgeworth defined activities as complements if doing (more of) any one of
them increases the returns to doing (more of) the others.
其中,埃奇沃斯补充说明了他的思想:如果任何一个人做了(或更多)贡献,那么(更多)
的人会因此得到更多的收益.
