This paper presents the discussion of the State intervention in the economy, regis-tering the present conceptions of economic thoughts. The view of the role of State in the different economic doctrines: the classic doctrine, the marxist doctrine, the keynesian doctrine, the structuralism of CEPAL (Economic Mission to Latin American) doctrine and the liberal monetarist doctrine is discussed. Then, he concludes that the contemporary crisis claims the appearing of a new paradigm that will have to develop itself through the neo-structuralism, post-Keynesianism and economic policy synthesis, in order to constitute a true scientific revolution.
