ABSTRACT
Technical transformations occurring in the economy and society often result from the setting up of new production facilities which in turn call for new qualifications, even though the facilities are themselves the product of man's work. This chapter analyses the rhythm and structure of the investments realized in the economy before globally evaluating the forms of investment realization from a technological point of view. Most of the instrumental capital accumulation comes from foreign companies operating in the hydrocarbon sector, which received nearly 60 per cent of enterprise investments for the period. In 1967–1978 periods, an extremely rapid acceleration of the annual investment volume can be observed: at current prices, the annual volume went from DA 3.2 billion in 1967–1969 to 9.2 billion in 1970–73, 30.2 billion between 1974 and 1977 and finally 52 billion in 1978. 1979–1986 was characterized by the restructuring of investment and the decrease in the overall investment rhythm.
