The most far-reaching statement on agricultural policy is embodied in Kim Il-sung's 1964 "Theses on the Socialist Agrarian Question in Our Country", which underscores the government's concern for agricultural development. Kim emphasized technological and educational progress in the countryside as well as collective forms of ownership and management. As industrialization progressed, the share of agriculture, forestry, and fisheries in the total national output declined from 63.5% and 31.4%, respectively, in 1945 and 1946, to a low of 26.8% in 1990. Their share in the labor force also declined from 57.6% in 1960 to 34.4% in 1989.
