In 1951, there were 433 temporary mutual aid groups in the county, with 8,311 farmers, accounting for 9.44% of the total farmers. The enrolled population is 35,111, accounting for 9.71% of the total agricultural population; The cultivated land is 75,111 mu, accounting for 7.35% of the total cultivated land. In 1951, a perennial mutual aid group was established, with 25 households and 121 people and 361 mu of cultivated land. By 1954, the number of temporary mutual aid groups in the county had grown to 3154, with 2474 farmers, accounting for 27.56% of the total farmers; The enrolled population is 113611, accounting for 28.51% of the total agricultural population; There are 298,771 mu of cultivated land, accounting for 23.11% of the total cultivated land. There are 2376 perennial mutual aid groups and 23187 farmers, accounting for 25.71% of the total farmers; The enrolled population is 119813, accounting for 27.56% of the total agricultural population; The land is 313,111 mu, accounting for 23.32% of the total cultivated land. The temporary mutual aid group will return the proceeds and change jobs for jobs. In the perennial mutual aid group, attendance is recorded, and more work is paid, and more work is paid. It has played a promoting role in exerting human, animal and soil resources, overcoming famine and developing production.

in p>1952, two primary agricultural production cooperatives, Longhai and Lianmin, were set up on a trial basis. By 1956, there were 279 primary agricultural production cooperatives with 21,215 farmers, accounting for 22.33% of the total farmers. 89,113 people joined the society, accounting for 21.73% of the total agricultural population; There are 276,219 mu of cultivated land, accounting for 21.24% of the total cultivated land. Established 121 advanced agricultural production cooperatives, with 69,193 farmers, accounting for 72.71% of the total farmers; 315,361 people joined the society, accounting for 74.48% of the total agricultural population; 974,251 mu of cultivated land, accounting for 74.92% of the total cultivated land. In 1957, due to the decline in income of some advanced agricultural production cooperatives, there was a phenomenon that a few members quit the cooperative.

in September, 1958, 172 advanced agricultural production cooperatives were merged to form six people's communes, and the county realized commune. People's communes implement the management system of "integration of politics and society". The commune has several production brigades, and the production brigade has several production teams. The commune and the production brigade set up management committees respectively, and the production teams set up team committees. The means of production are collectively owned and the commune is the economic accounting unit. At the beginning, it was free to run a large canteen to eat, and the production brigade was changed to battalion, company, platoon and class establishment, so as to collectivize production, militarize organization, combat action, and uniformly allocate labor to carry out "large corps operations." Commanding recklessly, exaggerating wind and * * * wind are rampant, which has dampened the enthusiasm of the masses, and production has declined year after year. The total grain output was 91 million Jin in 1958, 85 million Jin in 1959, 45 million Jin in 1961 and 111 million Jin in 1962.

at the end of September, 1961, six people's communes were divided into 15 communes. In 1962, the "Regulations on the Work of Rural People's Communes (Draft)" of the Central Committee of the Communist Party of China was implemented, and the system based on three levels (commune, brigade and production team) with the production team as the basic accounting unit was determined. It promoted the recovery and development of agricultural production, and the total grain output rose to 56 million Jin in 1964 and 71 million Jin in 1966.

in p>1978, after the third plenary session of the 11th CPC Central Committee, the rural economic system was reformed and the contract responsibility system was implemented. At first, because the "Left" thought has not been eliminated, only a few production teams implemented the quota management of contracting work in small sections, and contracted some crops (cotton, corn, sweet potato, etc.) to households. In September, 1981, the county party committee carried out the Notice of the Central Committee on Printing and Distributing Several Issues on Further Strengthening and Perfecting the Responsibility System for Agricultural Production, which improved the understanding of the responsibility system for agricultural production and expanded the scope of "fixing production quotas to households". It was not until 1982 that the resistance was really broken and the contract responsibility system was fully implemented.

the contract responsibility system for joint production still adheres to the system of public ownership of land, giving overall consideration to the interests of the state, the collective and the individual. Except for a small amount of land reserved by the production team (for supplying the increased population), the rest of the land is fixed at the household level. Contractors only have the right to use and are not allowed to buy or sell. In addition to the payment of agricultural tax and collective retention, the rest are owned by individual contractors. The enthusiasm of farmers was mobilized, and production developed rapidly. In 1983, the total agricultural output value was 232.58 million yuan, and the total grain output was 427 million Jin, a record high. In 1985, the total agricultural output value was 241.26 million yuan, and the total grain output was 441 million Jin. With the continuous improvement of the contract responsibility system, a large number of specialized households and new economic consortia emerged. By 1985, there were 2158 specialized households in the county, including 897 planting households. There are 22 households in forestry, 123 in animal husbandry, 16 in fishery, 228 in industry, 411 in transportation, 33 in building materials, 331 in commercial catering service and 97 in other households, with 3,973 professional laborers, with an annual total income of RMB 1118,111, including 7.614 million from professional production. There are 442 new economic complexes, including 1 for planting, 2 for forestry, 5 for animal husbandry, 32 for fishery, 217 for industry, 33 for transportation, 78 for construction, 33 for commercial catering service and 41 for others. It has 4.186 million yuan of fixed assets and 5,751 employees, with an annual total income of 11.297 million yuan and an allocation of 3.572 million yuan in that year. In the late Qing Dynasty and the early Republic of China, the handicraft industry in Dangshan County, a privately-owned individual, mainly consisted of earthenware weaving, earthenware spinning, silk reeling, bricks and tiles, etc. The handicraft workshops in market towns were mainly iron, wood, bamboo, silverware, bronze, tin, printing and dyeing, ceramics, yellow smoke, sewing, brewing and other industries, and the scale of the workshops was mostly 2-5 people, only a few manufacturers had a large number. In 31 years of the Republic of China (1941), the four workshops jointly run by Wang Ziliang, Wang Wangshi, Wu Jianwei and Lu Changshi had 13 employees by 35 years of the Republic of China, which was also the largest workshop in Dangshan County at that time. At the end of 37, six cigarette shops organized themselves and set up three small hand-made cigarette factories. In the spring of 38th year of the Republic of China, nine people, led by Shan Chengxian and Feng Junjie, organized a woodworking transportation cooperative, which was later renamed the iron and wood production cooperative. In 1951, three small cigarette factories, Qunli, Huada and Shinjuku, merged into a public-private joint venture Shinjuku cigarette factory. On April 1, 1952, the privately-owned Xinsheng Pot Factory and two privately-owned furnaces, Dongshan Liu and Yang Jinzhong, jointly established the People's Iron Factory in Dangshan County. That year, Zhang Zongxian organized 18 individual craftsmen in the city of knitting, spinning, cotton, weaving and silk, and established a knitting club. In 1953, Dangcheng set up two sewing groups in succession, and in 1956, it organized cooperatives and groups in an all-round way. By the end of the year, the socialist transformation of private handicrafts was basically completed, and the county * * * established 16 handicraft production societies with collective management and self-financing with 525 employees.

since p>1978, the self-employed economy has been actively supported, and the self-employed handicraft industry has been restored and developed. There are many craftsmen in county towns and towns to set up stalls or walk the streets to serve consumers directly. With the implementation of the economic system reform and opening-up policy, industrial "specialized households" and "new economic complexes" have appeared in rural areas, and industrial "self-employed households" and small factories run by private companies have appeared in towns. According to statistics, In 1985, there were 228 specialized households engaged in industry in rural areas of the county, with 423 workers engaged in industry, with an industrial income of 1.22 million yuan, and 217 new economic complexes engaged in industry, with 3,264 employees, the original value of fixed assets was 2.717 million yuan, the total income was 7.519 million yuan, the net income was 2.534 million yuan and the tax was 268,111 yuan.

collective industry county runs collective industry. At the end of 1956, more than 95% of individual craftsmen in industries such as iron, wood, sewing, textile, bamboo ware, printing and dyeing, yellow smoke, construction, scale making, lettering, watch repair and so on embarked on the road of collectivization, forming 11 societies and groups, with 419 employees. In 1958, 12 collectively-owned enterprises were changed to enterprises owned by the whole people, and rural collective enterprises were assigned to commune management. In 1962, these 12 factories and cooperatives were reorganized into collective-owned enterprises. In 1955, there were 8 factories and cooperatives belonging to the Second Light Industry, including clothing factory, printing and dyeing factory, pot factory, wood factory, vehicle company, watch company, bamboo company and shoe company, with 392 employees, with a total output value of 919,111 yuan and the original value of fixed assets of 194,111 yuan. By the end of 1976, there were 8 units belonging to the General Machinery Factory, Textile Factory, Woodware Factory, Clothing Factory, Bamboo Club, Watch Club, Construction Club and Management Department of the Second Light Industry, and there were 1131 employees. The total industrial output value is 3.255 million yuan, the original value of fixed assets is 1.25 million yuan, and the total profit is 1.46 million yuan. In 1984, it was adjusted again. In 1985, there were 851 employees in 9 factories, agencies and departments, such as Woodwork Factory, Clothing Factory No.1, Clothing Factory No.2, Machine Factory, Standard Parts Factory, Textile Factory, Line Carpet Factory, Watch Club and Management Department of Second Light Industry. The total industrial output value is 4.474 million yuan, the original value of fixed assets is 2.177 million yuan, and the total profit is 1.56 million yuan.

State-owned industrial counties run state-owned industries. In February of 1952, Wu Zhonglie's private printing company was confiscated, and the state-owned Dangshan People's Printing Factory was established. This was the first county-run state-owned industry in Dangshan County. At that time, there were 6 employees, and the factory address was at the sales department of the current vegetable company (No.175 Renmin Road). There are only 1 lithographs and 1 lead printers. The annual output value is 8,111 yuan, and there are fixed assets of 1,111 yuan. Later, a county-owned state-owned lime kiln factory was set up in the south of the city of Dangcheng. At that time, there were 7 employees and only 1 lime kilns, with an annual output value of 5,111 yuan and fixed assets of 1,111 yuan. In April, 1955, the local state-owned Dangshan County Winery was opened, and its site was in the south pass of Dangcheng. At that time, there were 19 employees, 12 wine pits and 1 cauldrons, with an annual output value of 14,111 yuan and fixed assets of 1,111 yuan. A local state-owned brick and tile kiln factory was set up, located in the south of Lizhuang Railway Station. At that time, there were 65 employees, with an annual output value of 1.39 thousand yuan, fixed assets of 1.3 thousand yuan, and the main equipment was 2 brick and tile kilns and 2 lime kilns.

In p>1958, the county-owned state-owned industries were: iron ore quarry, general machinery factory, Wujinjiaodian, explosive factory, chemical factory, granular fertilizer factory, ceramic factory, yellow tobacco factory, glorious paper factory, fiber processing factory, livestock processing factory, power plant, vehicle factory, agricultural machinery repair factory, wood factory, knitting factory, sack factory, sandpaper factory, etc. In the second half of 1959, the adjustment began. By 1963, there were 7 state-owned industries in Dangshan County, including power plant, comprehensive farm tools machinery factory, tractor repair factory, brick kiln factory, brewery, yellow tobacco factory and printing factory.

since the "cultural revolution" in p>1966, most factories were paralyzed and semi-paralyzed. In 1971, the production of agricultural machinery became prosperous. The comprehensive farm tool machinery factory was changed to the agricultural machinery repair and manufacturing factory (referred to as the first agricultural machinery factory), the tractor station was changed to the second agricultural machinery repair and manufacturing factory (referred to as the second agricultural machinery factory), and the S195 diesel engine began mass production. That year, only No.1 Agricultural Machinery Factory produced 212 sets. State-owned industrial production in several other counties has also begun to pick up. From 1971 to 1976, cement plant, rubber plant, fertilizer plant, chemical plant and phosphate fertilizer plant were set up successively. By 1976, the county owned 12 state-owned industries, including No.1 Agricultural Machinery Factory, No.2 Agricultural Machinery Factory, Rubber Factory, Fertilizer Factory, Phosphate Fertilizer Factory, Chemical Factory, Cement Factory, Brick Kiln Factory, Cigarette Factory, Brewery, Paper Mill and Printing Factory. There are 1,511 employees and the total industrial output value is 1,679,891 yuan.

since p>1978, the policy of "adjustment, reform, rectification and improvement" has been carried out, and the county-owned state-owned industries have been adjusted, and enterprises with emphasis on improving product quality and paying attention to economic benefits have been reorganized, and the autonomy of enterprises has been gradually expanded, and various forms of contract responsibility system have been implemented, so that the county-owned state-owned industries have achieved new development. According to the statistics in 1985, there are 16 county-owned state-owned industries (from 12, paper mills were changed into carton factories). There are 4 new juice factories, two brick factories, weaving factories and power supply industries), 11 industries (brewing, fruit processing, cigarettes, textiles, paper-making, printing, electricity, chemistry, building materials and machinery), with 3,961 employees, with a total industrial output value of 43.287 million yuan, a net output value of 13.863 million yuan and an original value of 27.142 million yuan of fixed assets.
