The G6 was formed in reaction to certain economic conditions that began back in 1973. The world economic frameworkat that time was experiencing high unemployment, high inflation, the rapid devaluation of the U.S. dollar and energy shortages brought about by a global oil crisis. Under the suggestion of then French President Valéry Giscard d'Estaing, the leaders of the largest six industrialized nations decided toget together for talks to find solutions for these purely economic problems. The first meeting of G6 leaders was an informal affair and not considered a summit.

而G6当年成立的原因是因为在1973年的时候，世界经济体系受困於高失业率、通货膨胀、美元的快速贬值以及肇因於石油危机的能源短缺问题，因此在法国总统季斯卡的提议之下，当年六大工业国的元首决定共同商议，找寻解决这些单纯经济问题的方法。G6因此成为当年各元首非正式会面，讨论问题的一个非正式论坛。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
