The combination of loans, incentives, subsidies and information, and the government emphasis on strengthening the role of the private sector especially during the course of the Fifth and Sixth Development Plans (1990-94 and 1995-99), and now under the Seventh Plan (2000-04), have clearly had the desired result. While the overall GDP for 1999 amounted to 139 billion U.S. dollars, the GDP for the private sector was U.S. $ 58.67 billion, almost 42 percent of the total. Industrial goods produced by this sector constitute more than one quarter of this amount, and about 20 percent of these are exported. During the last decade of the 20th century, the private sector contributed more to the country's GDP than did the oil sector. Moreover, the country has seen a decrease in imports, directly proportional to the increase in domestic production.
