Up 2 places year-on-year. Economic Development Zone Dingyuan Industrial Park was established with the approval of the provincial government in February 2006, with a planned area of ??2 square kilometers. As of 2013, it has been built into an emerging economic zone with reasonable layout, complete functions, complete facilities, and full of vitality. More than 100 enterprises from inside and outside the province have settled there, with a total investment of more than 12 billion yuan. It has initially formed a zone focusing on equipment manufacturing, light textiles, clothing, The four major industries of deep processing of agricultural and forestry by-products, new energy and new materials have taken shape.
On August 4, 2013, with the approval of the Anhui Provincial Government, Dingyuan Industrial Park was renamed "Anhui Dingyuan Economic Development Zone", and the planned expansion area of ??Dingyuan Economic Development Zone was initially determined to be 17.3 square meters. kilometer. Salt Chemical Industrial Park In April 2005, the Dingyuan Coal Chemical and Salt Chemical Integrated Project was officially approved. The project covers an area of ??390 hectares and has a total construction investment of 16 billion yuan. It was included in the "861" No. 1 Project of Anhui Province. In March 2011, Dingyuan Salt Chemical Industrial Park was approved as a provincial-level salt chemical industrial park. Its function is positioned as a demonstration base for industrial transfer in the Wanjiang urban belt and a key development salt chemical industrial park in Anhui Province. It takes the production of "two alkali" (caustic soda and soda ash) as the leader and strives to build a "100-billion-dollar ecological salt chemical industry base". ". During the Republic of China, handicraft production became active. Five craftsmen (carpenters, blacksmiths, stonemasons, craftsmen, and masons) and six craftsmen (husking mills, grain mills, oil mills, powder mills, dyeing mills, and tofu mills) were spread throughout the villages and towns, and printing, cigarettes, etc. appeared one after another.
In the 14th year of the Republic of China (1925), Zhou Youting founded his first factory in Dingcheng, a printing factory. Zhou bought a lithographic plate from Nanjing, engraving and printing, and undertook simple businesses such as printing letterheads, envelopes, and invitations. , business is booming and the scale is gradually expanding.
In the 27th year of the Republic of China (1938), the Japanese imperialists invaded Dingcheng and burned, killed, looted and captured everywhere. The Zhou family fled to Hankou, but returned two years later and reopened their business. In the 29th year of the Republic of China (1940), the Wandong Anti-Japanese Base Area under the leadership of the Communist Party of China established quilt factories, leather factories, and oil pressing factories in the Dongyangzhuang and Deshengji areas near Outang. Liu Huazhang set up a small cigarette factory in Dingcheng. In addition, the successive emergence of "five craftsmen" and "six craftsmen" formed the bud of fixed industry. According to statistics, in 1949, there were 3,394 households with 5,732 people engaged in handicraft production in the county, with an annual output value of 4.38 million yuan, accounting for approximately 12% of the total industrial and agricultural output value.
After the founding of New China, after a three-year recovery period, production has developed to a certain extent. In 1953, socialist transformation of agriculture, handicrafts, and capitalist industry and commerce began, and farmers engaged in handicraft production were organized into the Iron Wood Industry Society. Chen Yusheng, Chen Ruhai and others took the lead in establishing Dingyuan County Agricultural Tools Factory. That year, there were 2,088 households with 2,820 individual craftsmen. In 1956, the socialist transformation of capitalist industry and commerce was basically completed. Most individual craftsmen joined cooperatives, and only 150 people persisted in individual production.
In 1958, a large-scale development of steel was launched. The county has built or expanded 54 state-owned factories. The number of employees in the company increased from 20 in 1951 to 13,197. In 1960, many companies suffered serious losses due to insufficient funds, backward technology, and poor product quality. In 1962, it was forced to make adjustments. Except for the printing factory and the winery, most of the other factories were closed, suspended, merged, or transferred. This year's total industrial output value was only 3.96 million yuan, down 29% from 5.56 million yuan in 1956, marking the first major industrial decline after the founding of the People's Republic of China.
In the ten years of the "Cultural Revolution", the rules and regulations of industrial and mining enterprises were destroyed. Factories were in a state of chaos for a long time, with output values ??declining and serious losses. According to statistics, the county's total industrial output value was only 3.96 million yuan in 1968, returning to the level of 1962 and the early days of the founding of the People's Republic of China, marking the second major industrial decline after the founding of the People's Republic of China.
In the 1970s, Dingyuan County's industry has experienced great development, and key enterprises such as cement plants, wheel kiln plants, chemical fertilizer plants, phosphate fertilizer plants, and dyeing and weaving plants have been established. At the same time, county collective enterprises and township enterprises also began to develop. According to statistics, the county's total industrial output value rose to 33.37 million yuan in 1979. It increased more than 8 times compared with 1968 during the Cultural Revolution, of which township and village enterprises accounted for about 30%.
In the 1980s, county-run industries developed rapidly under the guidance of the policies of reform, opening up, and invigoration. In 1985, the county's total industrial output value exceeded 100 million yuan (102.82 million yuan), more than double that of 1980 (38.71 million yuan); fixed assets increased from 17.76 million yuan in 1980 to 39.08 million yuan; profits and taxes It increased from 4.12 million yuan in 1980 to 9.46 million yuan. The development of industry has put forward higher requirements for science, technology and management. County-run industries have actively increased investment, promoted technological progress, carried out the "double increase and double festival" campaign, strengthened enterprise management, and successively expanded and renovated a number of old enterprises. Quality and technical level have been improved. In 1988, the county's total industrial output value reached 240 million yuan, more than doubling on the basis of 1985. Achieved profits and taxes of 27.35 million yuan, the highest level in history.
In the second half of 1988, the central government put forward a call for governance and rectification and reduction of investment in capital construction, which affected some development projects of county-owned industries to a certain extent. After a short period of clean-up and rectification, in 1989 the county party committee and the county government once again required the county to enhance its awareness of industrial development, continue to develop large-scale industries, and accelerate the pace of industrial development. The key projects constructed in that year include: the first phase of the salt mine with an annual output of 100,000 tons of refined salt, the expansion project of the fertilizer plant with an annual output of 25,000 tons of synthetic ammonia, the expansion project of the cement plant with an annual output of 44,000-88,000 tons of cement, and the 20,000-ton sulfuric acid production line of the phosphate fertilizer plant. , the yarn-dyed fabric production line of the dyeing and weaving factory, the 1/4-set sack production line of the linen spinning factory, the expansion project of Dingcheng Rice Factory with a daily output of 150 tons of rice, the production workshop building of the printing factory, the vertical cylinder warehouse of the flour mill and the electronic weighing workshop of the overhaul factory. In 1990, the 40,000-ton urea project of the fertilizer plant was approved to start construction (it was put into operation at the end of 1991); non-industrial enterprises - school-run industries developed healthily. The former Experimental Primary School Aluminum Foil Factory was established in 1986 and achieved an output value of over 10 million yuan in 1989. Profits and taxes exceed one million yuan.
The three pillar industries of grain, oil and food processing, building materials, and chemicals have a relatively solid foundation; textile and clothing, printing, packaging, and machinery industries have also developed simultaneously; township and village enterprises have suddenly emerged and occupy an important position in one-third of the world; Dingcheng Two key industrial zones, Luqiao and Dingcheng grain, oil and food processing base, Quanwushan building materials base, Dongxing salt chemical industry base and Luqiao agricultural chemical base have all been built. In that year, the county's industry began to take shape, with fixed assets of 112 million yuan and a total industrial output value of 399.1 million yuan. The annual growth rate ranked third in the region. In 2012, the completed scale industrial added value was 1.7 billion yuan, an increase of 18.5%, ranking second in the city; the industrial fixed asset investment was 5.5 billion yuan, an increase of 10%; the total foreign trade import and export volume was 15 million US dollars, ranking first in the city ; Used foreign capital to achieve a major breakthrough, reaching 10 million US dollars. There are 81 large-scale industrial enterprises, 22 new ones. More than 42 million yuan of small and medium-sized enterprise incentive funds were cashed in, and 434 new non-public enterprises and 1,588 individual industrial and commercial households were established. Accelerate the transformation of development mode, investing 2.1 billion yuan in industrial technological transformation, an increase of 45%. Two new high-tech enterprises were established and 360 patents were applied for. It supported the transformation of 14 corporate patents and achieved a cumulative output value of more than 200 million yuan in high-tech products.
Salt Industry
In April 2005, the Dingyuan coalification-salinization integrated project was officially approved. The project covers an area of ??390 hectares and has a total construction investment of 16 billion yuan. It was included in Anhui Provincial "861" No. 1 Project. In March 2011, Dingyuan Salt Chemical Industrial Park was approved as a provincial-level salt chemical industrial park. Its function is positioned as a demonstration base for industrial transfer in the Wanjiang urban belt and a key development salt chemical industrial park in Anhui Province. It takes the production of "two alkali" (caustic soda and soda ash) as the leader and strives to build a "100-billion ecological salt chemical industry base". ". Dingyuan is the most important agricultural and sideline products base in eastern Anhui, an important national modern agricultural industry base, and one of the top 100 counties in China for grain, oil, and meat, ranking among the top in Anhui Province. Agricultural and sideline products are rich in various agricultural and sideline products such as rice, wheat, oilseeds, cotton, livestock and poultry, corn, potatoes, beans and aquatic products. In 2002, the total grain output ranked 26th in China, and the total oil output ranked 27th in China. Dingyuan lean pigs are one of the 31 fine breed pigs in China. From 1996 to 2002, they have been among the "Top Ten Animal Husbandry Counties in Anhui Province" for six consecutive years. Six major agricultural and sideline product bases have been built, including grain and oil, pigs, cotton, peanuts, aquatic products, and vegetables. In 2011 and 2012, it won the title of "National Advanced County in Grain Production" for two consecutive years. Livestock breeding industry is developed. There are 1.8 million pigs on hand all year round, and 1.1 million pigs are sold for slaughter. In 1987, it was listed as a national lean pig base. From 1996 to 2009, it ranked among the top ten counties in animal husbandry production in Anhui Province for 14 consecutive years, and its annual pig population ranked first in the province. Second, for the first time, the total meat output ranked 88th among the top 100 counties in China and 6th in Anhui Province. Since ancient times, agriculture has played an important role in Dingyuan County. According to the "Original Edition of the Complete Collection of Taxes and Services": During the Chongzhen period of the Ming Dynasty, there were 1,414 hectares of cultivated land in Dingyuan, with 24,620 taels of silver required, and 4,383 taels of silver required for regular people. In the sixth year of the reign of Emperor Yongzheng of the Qing Dynasty (1728), the practice of "dividing the land into one mu" was implemented, and the people paid 29,036 taels of silver. In the 37th year of the Republic of China (1948), the county's total annual fiscal revenue was 5.3 billion (old currency), of which land tax was 2.3 billion, accounting for 43%.
In the early days of the founding of the People's Republic of China, due to weak agricultural infrastructure, production levels were low and output was not high. In 1949, the county's total grain output was 246 million jins, and the per capita output was 513 jins. Grain production stagnated for more than 20 years after that, but developed from 1972 to 1977. In 1977, the total grain output was 570 million kilograms, with an average of more than 800 kilograms per capita.
After 1979, the household contract responsibility system was implemented in rural areas, which mobilized farmers' enthusiasm for production. In addition, they built water conservancy projects, improved soil, increased agricultural inputs, and promoted agriculture through science and technology, which promoted the great development of grain production. . In 1980, 600 million jins of grain were produced. In 1985, the output was 970 million jins. In 1986, the output exceeded 1 billion jins, reaching 1.1 billion jins. After 1987, it gradually transformed from output-based agriculture to profit-based agriculture, and from traditional agriculture to modern agriculture. In 1988, it became one of the 12 major grain-selling counties in China. In 1989, its grain and oil production entered the ranks of China's "Top 100" counties. Grain production ranked 48th in China and 6th in the province; oilseed production ranked first in the province. 13th in China.
In 1990, grain output reached a new level, with an output of 1.46 billion kilograms, and an average of more than 1,800 kilograms per capita, which was 2.6 times that before the implementation of the responsibility system. The total output of oil crops has risen to the 10th place in China, and the total grain output ranks 33rd in China. In 2012, the total grain output was 2.2 billion jin, an increase of 5.3%, achieving "nine consecutive increases". One new national-level livestock and poultry standardized breeding demonstration farm and three municipal-level demonstration farms were added, with 1.436 million pigs produced for slaughter. It continues to maintain its status as a major pig transfer county in China. We took the lead in establishing the Pig Industry Technology Innovation Strategic Alliance and the Dingyuan Rice Circular Economy Technology Innovation Strategic Alliance in Anhui Province. Through the implementation of the agricultural machinery prosperity project, the total power of agricultural machinery in the county reached 1.382 million kilowatts, and the number of tractors ranked first in the city. With the implementation of the agricultural industrialization project, the number of provincial and municipal leading enterprises in the county has increased to 21, the number of farmer cooperatives has increased to 521, and 4 new famous trademarks and 9 green foods have been added. The forestry "Double Hundred and Double Ten" project was implemented, and 39,000 acres of afforestation and greening were completed, with the forest coverage rate reaching 8.5%.
