Abstract
This paper deals with the co-operative sector, in Laidlaw report at Moscow in 1980, and the
history of the theme in Canadian school and French school.
Laidlaw said that he was not only taught by the co-operative sector advocated Georges Fauquet,
but also by ”four ownership types” inspired Moses Coady's view. In short, Laidlaw re-arranged the
idea of predecessors ingeniously a la mode, adding his plentiful overseas experiences.
