As nouns the difference between collectivism and corporatism

is that collectivism is an economic system in which the means of production and distribution are owned and controlled by the people collectively while corporatism is political/economic system in which power is exercised through large organizations (businesses, trade unions, their associated lobbying efforts, etc) working in concert or conflict with each other; usually with the goal of influencing or subsuming the direction of the state and generally only to benefit their own socioeconomic agendas at the expense of the will of the people, and to the detriment of the common good.
