Welcome consultation
While doing well in energy saving and emission reduction, enterprises should actively carry out system integration and project contracting, strive to provide users with complete solutions, and develop modern manufacturing; five, enterprises should not only have market concept, but also enhance the sense of social responsibility. Pay attention to the good social image of the enterprise, care for the workers, let the reform achievements be shared by the workers and staff, care about energy conservation and emission reduction, and make efforts to build a harmonious society.
Speech by Cai Weici, vice president of China machinery industry federation.
China Machinery Industry Federation special consultant and former Vice Minister of the Ministry of machinery industry, Chinese Electrical Appliances Association honorary president Liu Yansun pointed out in his speech: Chinese power equipment manufacturing industry has experienced fifty years of struggle, has become a independent equipment power sector, complete national strategic industry, to meet the needs of the rapid development of the national power economy. In particular, more than twenty years of implementation of the reform and opening up policy, the introduction of advanced manufacturing technology to digest the western countries, combined with national conditions, independent innovation, has reached the same level in the world. The growth of the national economy and the growth of electricity consumption have different proportions in different stages of development. According to the new measurement of the Ministry of power, the power generation capacity of 2 years is 3 billion 800 million kwh, the installed capacity is 8 million 520 thousand KW, the power generation capacity of 22 years will reach 6 billion 500 million kwh, and the installed capacity is 330 thousand KW. The development of China's wind power equipment manufacturing industry is a process of increasing awareness, more than 2 years, until the end of 25, the total installed capacity is only 266 thousand KW, the new capacity of 53 thousand KW, the growth rate of 24 years, the new capacity of 98 thousand KW 254%. The 26 year is the year of implementing the renewable energy law in China, and the pace of wind power construction has been significantly accelerated. According to incomplete statistics, by the end of 26, the country has built about 8 wind farms, installed capacity of about 230 thousand kilowatts, more than 25 years installed capacity of more than 10000 kilowatts, an increase of more than 8%. In the next 3 years, the growth of the demand for electricity in developing countries and the recognition of the inevitable problems of greenhouse gas emissions will make nuclear power a clean energy that can be produced in large scale and sustainable. By the beginning of this century, there were 44 reactors in the world, 358 million kilowatts, generating capacity of 7%, installed capacity accounted for%, mainly in industrialized countries, France has reached 77%, Japan accounted for 34%. There are now 25 reactors under construction, and the World Nuclear Association expects more than 22 power reactors to be built by the end of 26. The State Council approved the nuclear power medium and long term development plan, completed 22 years, total capacity of 40 thousand kilowatts, construction of 80 thousand kilowatts, construction funds of about 400 million yuan, of which the capital needs 800 million yuan, the focus is to solve the source of capital. It is an arduous task to achieve the goal of energy saving and emission reduction, which is the inevitable result of the heavy industrial structure of our country. In order to save energy and reduce emission, promote cleaner production, equipment manufacturing industry should also provide energy saving and cleaner production products for other industries, especially enterprises producing electrical equipment and electrical products. Efforts should be made to develop new energy-saving products and eliminate backward energy consuming products. This is not only a challenge, but also an opportunity for innovation and development.

At the forum in the afternoon, Fu Yuwu, Secretary General of the China Automotive Engineering Society, said: after several years of rapid growth, China's automobile market has maintained a rapid development trend in the first half of 27 years, and the speed, efficiency and quality exceeded our expectations. 26 years of car production and sales have accounted for 53.5% of the total production, more than half of all production; truck from the original dominant position, dropped to 26 years in 24.8%; passenger car production has been steady growth in the proportion of total output, showing a slow downward trend, 26 years is 22.77%. Exports continue to maintain a good momentum of development, the import and export market to maintain rapid growth, the growth rate is far greater than the domestic car market, vehicle exports continue to maintain steady growth, car exports outstanding performance. -5 months, the national automobile import and export goods accumulated a total of 23 billion 870 million, total imports of 9 billion 473 million, an increase of 8.88%; imported cars.8 million, an increase of 25.3%; exports amounted to 4 billion 344 million, an increase of 36.94%; export 88 thousand and 700 vehicles, an increase of 66.6%. He pointed out that the current automotive industry should pay special attention to several issues, one is to develop energy-saving cars; two is to implement clean gasoline and diesel, and international fuel standards. Vigorously develop various kinds of synthetic fuels and mix with gasoline and diesel to form clean fuel. In 22 years, the total amount of alternative fuels reached about 2% of the vehicle fuel consumption; the development of direct injection internal combustion engine and its hybrid power were focused on. When it comes to the development of key components, he said: the lack of core technology, key technology, lagging behind the automobile manufacturing technology, will be the bottleneck restricting the independent innovation and independent development of China's auto industry. The problem of the sustainable development of the series of products with the lack of localization supporting system has appeared in the past 27 years, which has sounded the alarm for the hollowing out of China's auto parts development. 26 years, the national auto parts enterprises sales revenue of 43 billion 500 million yuan, of which foreign capital (holding or sole proprietorship) parts occupy most of the market share, domestic parts accounted for only 2%~25%. Independent innovation capability promotion problem: at present, although China's autonomy has a certain market share, this is mainly rely on China's automobile low-end market start, with a low price, cost-effective access to market share. There are two crises behind its prosperity: first, the technical gap with foreign countries can not be effectively reduced; two, the joint venture collective price reduction will make the independent loss of competitiveness. China's automobile independent road should overcome the mentality of eager for quick success and instant benefit, and it is necessary to establish a set of scientific evaluation standards and audit supervision mechanism.
Wang Liming, vice director general of the China Machine Tool Industry Association, said in the introduction of the machine tool industry: "good macro environment promotes the prosperity and development of the industry, and the optimization of the demand structure leads to the optimization of the product structure.". Since the beginning of this year, enterprises have obviously improved their independent innovation ability, and successfully developed a number of CNC machines which are urgently needed in domestic key industries. The structure of the whole industry has changed significantly, and the private holding enterprises have developed rapidly, which has stimulated the development of the whole industry. Distinctive machine tool products are the characteristics of industrial agglomeration. Import growth slowed down in the first half of the year, and exports grew rapidly, but there was still a deficit. When it comes to the second half of the forecast, Wang Liming said: "the annual machine tool industry growth will certainly be much higher than expected, will be the world's largest consumer and importer of machine tools for sixth consecutive years, this year, CNC metal cutting machine tool output will be more than ten million units.". Exports will maintain rapid growth in the next two years, and imports are expected to maintain a steady trend. The machine tool industry should actively adjust the industrial and product structure through further deepening and reform, adapting to the market demand.
Wang Liming, vice director general of China Machine Tool Industry Association, delivered a speech.
Chinese Machinery Industry Federation chief engineer, China general machinery industry association chairman Sui Yongbin in his speech in detail introduces the situation of China's nuclear power technology in recent years, when it comes to the future development, he said, should speed up the development of CNC machine tools industry, persistent efforts to the development of CNC machine tool market to improve the product quality and comprehensive level. To improve the ability of independent innovation and deal with the relationship between expanding production capacity and improving independent innovation ability. In the domestic market demand is strong, pay attention to the development of the international market. Adjust industrial structure as soon as possible and develop functional components rapidly.
