The "12th Five-Year Plan for Machinery Industry Development" published by the China Federation of Machinery Industry on the 29th proposed that during the "Twelfth Five-Year Plan" period, China's machinery industry must "strive from big to strong" and strive to achieve the end of the "Twelfth Five-Year Plan". Six goals. The first is to maintain a steady and healthy development. The average annual growth rate of industrial output value, industrial added value, and main business income is maintained at about 12%, and the average annual export growth rate is about 15%. The economic benefits have gradually increased, and profit growth is slightly higher than the growth rate of production and sales. The total asset contribution rate has reached about 15%, the main business income profit rate has reached about 7.5%, and the industrial added value rate has reached about 28%. Second, the industry has made breakthroughs in upgrading to the high end. The industrial structure has been upgraded to the high end, and the proportion of modern manufacturing service industry has increased significantly. The proportion of the revenue of the modern manufacturing service industry of the top 100 machinery companies in the main business income has reached about 25%. The growth of high-end equipment is more than double the average growth rate of the entire industry, and the share of high-end equipment in the domestic market must be significantly improved. At the same time, the organizational structure is further optimized. The production concentration of the top 100 mechanical companies has reached about 20%, and the production concentration of the top five automotive companies has reached about 80%. Third, the capacity for independent innovation has increased significantly. The proportion of R&D expenditures of major and medium-sized enterprises in the main business income reached around 2.5%. Mastering the core technologies of a number of major products, the design and technical level of major technical equipment has been significantly improved, and major scientific and technological projects have achieved major results. The rate of production of new products increased to around 25%, and the number and quality of patents increased significantly. The international competitiveness of products has improved significantly. The fourth is the initial consolidation of the industrial base. The situation that the foundation lags behind the development of the mainframe has initially changed. The situation of over-importation of high-end CNC machine tools and basic manufacturing equipment has changed. The satisfaction rate of domestic high-end test instruments and automation and intelligent control systems in the domestic market has been significantly improved. The bottleneck of key components that restrict the development of high-end equipment has been eased. CNC machines and functional components in the machine tools, hydraulic systems for hydraulic excavators, and key bearings for wind power equipment have made major breakthroughs in localization. The level of basic technology has been significantly improved, breakthroughs have been made in core technologies and key processes, and mass production has been achieved. The high-end large-scale castings and forgings required for nuclear power equipment have been initially domesticated. The fifth is the significant increase in the level of integration between the two economies. Optimize R&D design process, advance design simulation and optimization, establish collaborative innovation and integrated innovation platform, and build a digital R&D design system. Deepen the infiltration and integration of information technology in mechanical products, promote the automation, intelligence and digitization of products, and increase the content and added value of product information technology. Cultivate a group of enterprises to realize the integration of informationization in the whole business process. Sixth, promote green manufacturing. The comprehensive energy consumption of the industrial value-added industry in the machinery industry has dropped from 0.425 tons of standard coal in 2009 to about 0.31 tons of standard coal in 2015, with an average annual reduction of 5.9%. The development of energy-saving electromechanical equipment has been vigorously promoted, and the design efficiency of general-purpose electromechanical products with a large number of products has increased dramatically. The fuel consumption of internal combustion engines should be reduced by 10%, and emissions must reach the international advanced level. The 2020 development goal is that China's machinery industry has entered the ranks of the world's most powerful countries, and it is in an advantageous position in the international competition. The international market share of the main products is among the top three in the world. It has basically mastered the core technologies of the leading products and has a number of The key products and well-known brands of independent intellectual property rights and the leading companies in key industries have entered the top three in the world.
