The 1990s famine paralyzed many of the Stalinist economic institutions. The government pursued Kim Jong-il's "Songun" policy, under which the military is deployed to direct production and infrastructure projects. As a consequence of the government's policy of establishing economic self-sufficiency, the North Korean economy has become increasingly isolated from that of the rest of the world, and its industrial development and structure do not reflect its international competitiveness. Domestic firms are shielded from international as well as domestic competition; the result is chronic inefficiency, poor quality, limited product diversity, and underutilization of plants. This protectionism also limits the size of the market for North Korean producers, which prevents taking advantage of economies of scale.
