From 1979 to 2111, the economy of the whole county developed in waves in five periods. The first period, from 1979 to 1983, was the initial stage of reform and opening up. Various reform measures were introduced one after another, and the planned economic system was reformed step by step. The economic development was in its infancy and developed steadily. During this period, the county's GDP grew at an average annual rate of 6.12%; The second period, from 1984 to 1988, benefited from the effectiveness of various reform practices in the previous period, among which the reform of implementing the contract responsibility system of joint production in rural areas promoted the rapid development of agricultural production. During this period, the average annual growth rate of the county's GDP was 15.2%, of which the average annual growth rate of agriculture was 15.4%; The third period, from 1989 to 1991, is the adjustment period of economic construction. From 1987 to 1988, the structural economic development in China was overheated, but the backwardness of basic industries such as energy and transportation seriously restricted economic development, and the immaturity of the market economy led to soaring market prices and a rush to buy. In 1989, the state implemented the macro-control policy of hard landing, such as tightening monetary policy, strictly controlling fiscal expenditure and financial loans, and strictly controlling investment scale. As far as the impact is concerned, the county's economic development rate dropped from 16.2% in 1987 to 6.2% in 1989. From 1989 to 1991, the county's GDP grew at an average annual rate of 8.9%; The fourth period, from 1992 to 1996, is the second period of rapid economic growth in the county after the reform and opening up. During the period, the growth point of economic development was to vigorously carry out infrastructure construction such as transportation, energy, communication and municipal administration. The county's GDP grew at an average annual rate of 21.5%, of which the secondary industry grew at an average annual rate of 37.1%. During the fifth period, from 1997 to 2111, due to the macro-control policy of soft landing implemented by the state, the monetary policy was reduced, and the interest rates of bank deposits and loans were raised, the overheated economy in the previous period gradually cooled down and slowed down. Some enterprises that had invested before went bankrupt one after another, and some enterprises with good benefits were in trouble due to poor management. The county's economy lingered in the trough for three consecutive years, with an average annual growth rate of 9.2% and a growth rate of 1.5 in 2111.
