Before this, the textile machinery industry also entered the State Council document. For example, Document 90 of 1985. Standardize the import of mechanical and electrical products, classify the import of mechanical and electrical products as the suspension of import products, unified attribution to joint foreign products, and only the policy of importing software products and restricting imported products. In recent years, the State Council has also issued products that guide the development of enterprises, which are classified as encouraged, permitted, restricted, and eliminated products. They also specify the categories, types, and specifications of products.
The documents of the State Council were discussed and approved by senior officials of the State Council and promulgated. All provinces, municipalities, autonomous regions, and governments at all levels must earnestly implement them, and their importance is very important.
Textile machinery industry belongs to the equipment manufacturing industry, is the special equipment manufacturing industry in the equipment manufacturing industry, and belongs to the manufacturing industry in the national economy. Equipment manufacturing industry is a basic industry that provides technical equipment for the development of national economy and national defense construction. Developing and rejuvenating the equipment manufacturing industry is an important task put forward by our party. It is a strategic move to study the scientific development concept, take a new road to industrialization, and achieve sustainable development of the national economy.
In accelerating the revitalization of the equipment manufacturing industry, the state has chosen to have an important influence on the national economic security and national defense construction. To achieve remarkable results in promoting the sustainable development of the national economy, it can actively promote structural adjustment and industrial upgrading. The major technological equipment that expands self-produced products and expands market share will be the focus, and policy support and guidance will be intensified to achieve major breakthroughs in key areas.
The textile machinery industry has been listed as a key development area for accelerating and revitalizing. The proposed products include localization of paraxylene (PX), terephthalic acid (PTA) and polyester complete sets of equipment in large-scale ethylene projects.
The textile machinery industry is included in the special projects for accelerating and invigorating key development areas. The new textile machinery products proposed for development include the polyester fiber staple fiber post-processing complete sets of equipment with a daily output of 200 tons or more, viscose filament continuous spinning equipment, and high efficiency. Modernized complete sets of cotton spinning equipment, mechanical and electrical integrated rapier looms and air-jet looms and other new sets of key equipment.
The key products proposed here are just one project and one topic. Each project is not just a simple single product but a complete set of equipment consisting of a variety of mainframes and control systems. These complete sets of equipment are not yet completed and implemented by a single company. For these key complete sets of equipment for technological research and industrialization, the ultimate goal is to serve the development of the textile industry, to promote the technical upgrading of the textile industry services.
The development of the textile machinery industry was included in the document of the State Council and pointed out that such specific requirements were indeed the first time in history. It was known that the responsibility was significant. Of course, the development of these key products to achieve the development goals is not an easy task. Relying on the efforts of the project companies depends on the coordination and support of the internal organizations of the industry, and it also depends on the support of the government. Since it has been listed as a key point, the state has also put forward some policy measures to support, develop, and revitalize.
The state has given some preferential policies in adjusting import taxation policies. Including import tariffs on some key components and raw materials that need to be imported by domestic manufacturers for the development and manufacture of these key equipment, and policies concerning the implementation of first-come-first-off policies for import value-added tax. Included in the list of products that can support these policies are: automatic winder, electromechanical integrated rapier and air jet looms, and viscose filament continuous spinning machines. The enterprises that produce these products will benefit from it, establish more confidence in the enterprise, and take active measures to promote the industrialization of these key products.
At the same time, the implementation of the VAT policy of the first-in-advance import link is also being continuously improved and improved. First, it is used as a national capital investment and used by enterprises, and later it is adjusted to exempt from import tariffs and preferential policies for value-added tax for import links. Relevant state departments have formulated detailed implementation rules. The policy is good for the enterprise, the enterprise gets benefits, promotes the production development of the enterprise, and improves the product technology. Actually, it is also “fishing fishâ€. Five companies that produce automatic winders and shuttleless looms have already benefited.
In order to encourage the ordering and use of China's first (sets) of major technical equipment in one step, the state has also given preferential policies to encourage “enlightened users†and encourage the “first crab†project.
The state has also increased funding support for major technical equipment, which is also relatively realistic. The State has established a major technological equipment innovation capacity building and R&D funds, and has given support to companies undertaking R&D and production of key products. The state supports enterprises that undertake key projects through discounted funds, subsidies, and capital injections through budgetary funds. Implement preferential policies such as pre-tax deductions for corporate R&D investment and encourage companies to increase R&D investment.
Thanks to the country’s attention and support for preferential policies, it also adhered to the combination of market competition and policy guidance, adhered to the combination of opening up and independent innovation, insisted on the combination of industrial restructuring and deepened enterprise reform, and adhered to the key The combination of development and comprehensive promotion of the policy, so that the textile machinery industry has not only benefited, but also achieved rapid development.
Policies and tactics are the life of the party. Leading comrades at all levels must pay full attention and must not be careless. Folk slang: One side of the policy, hit a large one, the policy is on the right, and a new level. Textile machinery industry, guided by correct policies, will certainly accelerate its development and advance to a higher level.
