What is machinery industry, chemical plant and machine tool plant?

Machinery industry (English: Machine Industry) In a broad sense, machinery industry refers to any industrial sector that uses metal cutting machines to engage in industrial production activities. Machinery industry in a narrow sense: refers to machinery manufacturing. The latter is usually used. The machinery industry is called "the heart of industry". It is the means of production of other economic sectors, and it can also be said that it is the basis for the development of all economic sectors. Its development level is an important symbol to measure the degree of industrialization of a country. In order to promote the modernization of ethnic areas, we must speed up the development of machinery industry. [Edit this paragraph] (1) The development and layout of machinery industry In old China, most of the machinery industry was small-scale, poorly equipped and low-productivity machine assembly, repair and parts manufacturing, which accounted for a small proportion in the whole national economy, and most of them were concentrated in coastal cities and a few cities in the mainland, such as Taiyuan, Chongqing and Wuhan. In ethnic areas, there are only a few crude repair industries. After the founding of People's Republic of China (PRC), with the rapid development of national machinery industry. The machinery industry in ethnic areas has also developed rapidly. Now, from the manufacture of general mechanical and electrical products to the manufacture of large-scale complex precision equipment and even electronic products, all provinces and regions have formed a relatively complete category. Modern machinery industrial system with reasonable layout, certain scale and technical level. A number of machinery industrial bases have emerged, such as transportation equipment manufacturing, electrical machinery and equipment manufacturing, instrumentation and measuring instruments manufacturing, mainly concentrated in Hohhot, Yinchuan, Urumqi, Kunming, Guiyang, Nanning, Liuzhou, Wuzhou and other cities. However, the machinery industry in ethnic areas can not meet the needs of its economic development. The main problems are: poor foundation, low production level, outdated equipment, high consumption, poor economic benefits, inconvenient transportation, ineffective information, poor adaptability, backward management, single products, lack of competitiveness and so on. Therefore, in recent years, under the guidance of the policy of "adjustment, reform, rectification and improvement", all provinces and regions attach great importance to the high-speed and reform, technological transformation and product renewal of the machinery industry centered on economic benefits, so as to make the machinery industry develop more harmoniously and healthily. [Edit this paragraph] (2) The main machinery industry departments and their distribution machinery industry can be divided into industrial equipment, agricultural machinery, transportation and other machinery manufacturing industries according to the service objects. 1. Industrial equipment manufacturing. Industrial equipment manufacturing refers to enterprises that produce various mechanical equipment of the equipment industry itself. It mainly includes heavy machinery, general machinery, machine tools, instruments and meters, electrical appliances manufacturing and textile industrial equipment. At present, there are few industrial equipment manufacturing enterprises in ethnic areas in China, but a number of small and medium-sized enterprises have been established in various provinces and regions, and new varieties have been continuously added, which has played a positive role in local economic development. For example, before the liberation of Guangxi, the machinery industry was very backward. At that time, the largest Liuzhou China Agricultural Machinery Company (the predecessor of Liuzhou Machinery Factory) had only 28 worn-out machine tools and 220 employees, and could only produce simple products such as manual oil presses and animal-drawn sugarcane presses. After liberation, Guangxi machinery industry developed rapidly. At present, the whole region has gradually formed a number of relatively complete manufacturing industries, such as agricultural machinery industry, electrical appliance industry, machine tool industry, petrochemical general machinery industry, instrument industry, heavy mining machinery industry, automobile industry, packaging machinery industry, general basic parts industry, bearing industry, etc. There are more than 2000 kinds of main products, of which more than 80 kinds have won the title of high-quality product award by the state, the Ministry of Machinery Industry and the autonomous region. More than 30 kinds of products such as machine tools, forging equipment, household appliances, walking tractors and mini-cars are exported to more than 20 countries and regions such as Hong Kong, Southeast Asia, France, the United States and Japan. In addition, the industrial equipment manufacturing industry in Inner Mongolia, Yunnan, Ningxia and other provinces has also developed rapidly. At present, it has industrial equipment manufacturing bases in Liuzhou, Nanning, Guilin, Wuzhou, Hohhot, Baotou, Jining, Ulanhot, Hailar, Kunming, Yinchuan and Wuzhong. 2. Agricultural machinery manufacturing. Agricultural machinery industry is an indispensable part of building modern agriculture, including all kinds of machinery production needed for agriculture, forestry, animal husbandry, sideline production and fishery production. Ethnic minority areas have a vast territory, and agricultural production has long occupied an important position, which has a broad market and demand for all kinds of agricultural machinery. Among many agricultural machinery, tractor is the most basic agricultural machinery. Liuzhou is one of the eight tractor production bases in China. There are various types of agricultural machinery enterprises in Urumqi, Kashgar, Xining, Yinchuan, Kunming and Guiyang. Hailar, Inner Mongolia is the main producing area of animal husbandry machinery, and other farm tools and accessories are produced all over the provinces. 3. Transportation machinery manufacturing industry. The transportation industry is an important part of the national economy, and the development of transportation machinery manufacturing industry is of great significance to promote the modernization of transportation in ethnic areas. Transportation machinery manufacturing industry includes railway rolling stock, automobile, ship and aircraft manufacturing industry. Due to the weak industrial base in ethnic areas, the development of transportation machinery manufacturing industry is slow. It mainly produces cars and motorcycles. For example, the automobile industry in Guangxi is a new and promising industry. After producing 2.5-ton and 5-ton trucks, Liuzhou Automobile Factory actively produces energy-saving minivans to meet the needs of the domestic market. The regional distribution is not balanced, mainly distributed in Guangxi, Inner Mongolia, Yunnan, Guizhou, Qinghai and Xinjiang.
