Пример употребления: Import substitution, economic policy adopted in most developing countries from the 1930s to the 1980s to promote industrialization by protecting domestic producers from the competition of imports. Protection—in the form of high tariffs or the restriction of imports through quotas—was applied indiscriminately, often to inherently high-cost industries that had no hope of ever becoming internationally competitive. (Encyclopædia Britannica).
The central pillar of the policy was import substitution, the belief that India needed to rely on internal markets for development, not international trade - a belief generated by a mixture of socialism and the experience of colonial exploitation. (BBC News).
