In 1984 industry, including the exploration, production, transport, and marketing of petroleum products (crude petroleum, natural gas, and condensates derived therefrom), contributed about 60 percent of GDP (at factor cost) and virtually 100 percent of exports. Industrial activities also occupied from 30 to 38 percent of the total labor force in 1984.
Libyan industrial development has been heavily dependent on the oil sector, both for investment revenue and for raw inputs. Throughout the 1970s, the government implemented numerous measures to increase its share of the profits from oil exploitation and marketing. By the mid-1980s, the revenue accruing to foreign oil companies engaged in lifting Libyan oil was taxed at a rate of about 95 percent.
