Since then, agriculture has gradually entered a stage of stagnation. In the mid-1960s, the economic structure of Taiwan Province Province began to transform, and gradually changed from an agriculture-based economy to an industry-based economy. Agriculture began to decline, and rural labor began to flow into cities and industry and commerce. Not only did the proportion of agricultural employed population continue to decline (it fell below 40% for the first time in 1969), but the absolute number of rural labor force also began to decline in 1970. The phenomenon of abandoned farmland has become increasingly obvious, land use has become extensive, crop multiple cropping index has declined, and traditional export agricultural products have gradually lost their overseas markets due to rising wage costs. 1969, agricultural production showed its first negative growth since the mid-1950s, and agricultural development entered a stagnant stage. The number of specialized farmers in rural areas decreased, and the proportion of specialized farmers in the total number of farmers decreased from 30.2% in 1970 to 8.9% in 1980; Farmers' agricultural income decreased, and the proportion of farmers' income in agricultural net income decreased from 48.7% to 26.4%. The average annual growth rate of agricultural production is 4. 1%, with negative growth for three consecutive years. Since the stagnation of agriculture in the late 1960s, the authorities of Taiwan Province Province have made major adjustments to their agricultural policies, from focusing on agricultural production and improving the self-sufficiency rate of grain to the all-round development of agriculture, rural areas and farmers' lives, and adopted a series of new policies and measures, but they have not changed the predicament faced by agricultural and rural development. Since 1980s, the authorities of Taiwan Province Province have comprehensively adjusted the agricultural policy, and the agricultural development has entered a new transition period. Its important policy measures include: 1980 amending and promulgating the Regulations on Agricultural Development; 1982 announced the second-stage agricultural reform plan and the third-stage plan to increase farmers' income and strengthen rural construction, and held the first "agricultural conference"; 1983, put forward the slogan of "training 80,000 peasant troops"; 1984 formulated the plan of "accelerating grass-roots construction and improving farmers' welfare", put forward the idea of developing "exquisite agriculture" and implemented the plan of "changing paddy fields into six years"; 1985 put forward "important measures to speed up agricultural upgrading, improve agricultural structure and increase farmers' income"; 1988 hold the second "peasant association"; 1990 put forward the slogan of "zero agricultural growth" and "comprehensive agricultural adjustment plan". All these plans and measures are aimed at changing the transformation of agricultural development from "quantity" to "quality".
However, since 1980s, although the growth rate of agricultural production has declined rapidly, the degree of agricultural specialization has improved. From 1980 to 1998, the average annual growth rate of agricultural production in Taiwan Province Province is only 1. 1%, of which 7 years are negative. In 2000, agricultural output decreased by 16%. However, the degree of agricultural specialization has improved and the proportion of professional farmers has increased. Among the farmers, the proportion of specialized households increased from 9% in 1980 to 12% in 1990, and reached 15.6% in 1999. Among non-cultivated farmers, the proportion of professional farmers rose from 7.4% to 65438+27.5% in 0990; Among farmers' income, the proportion of agricultural net income also began to rise, from 29.6% in 1980 to 35.2% in 1990.
