The prosperity of technology leads to the prosperity of the nation, and the strength of technology leads to the strength of the country. Since the new era, China has achieved numerous innovative breakthroughs in the field of science and technology, from 0 to 1 and from nothing to something. It has achieved a leap in scientific and technological strength from quantitative accumulation to quality, and from breakthroughs in points to upgrading system capabilities. This has provided strong support and growth space for constructing a new development pattern, promoting high-quality development, and accelerating the formation of new quality productivity. The convening of the 26th Annual Meeting of the China Association for Science and Technology is in line with the timing. The theme of this year's annual meeting is "Cultivating new productive forces to support high-level technological self-reliance and self-improvement.". New quality productivity refers to the power of technological innovation in modern economic development, continuously improving production efficiency, optimizing products and services, and promoting industrial upgrading and economic growth through new technological means such as digitization and intelligence. The core of new quality productivity is technological innovation. The continuous emergence of new technologies, products, processes, and models is changing traditional production methods at an unprecedented speed, improving production efficiency and quality. Utilize technologies such as digitization, big data, and artificial intelligence to achieve intelligent management, optimization, and collaboration, improve resource efficiency, and reduce costs. At the same time, it emphasizes service innovation, such as sharing economy, Internet of Things, cloud computing, etc., and emphasizes environmental friendliness, social responsibility, and sustainability. In the field of mechanical engineering, innovation leads and new productive forces promote development. We have also witnessed countless technological breakthroughs and innovations, which are driving the continuous development of new productive forces and injecting new vitality into industrial upgrading and economic growth. Intelligent manufacturing and industrial Internet, as the leaders among them, are leading a manufacturing revolution. Through the integration and application of cutting-edge technologies such as the Internet of Things, big data, and artificial intelligence, intelligent manufacturing has achieved digitalization, automation, and intelligence in the production process, which helps to improve production efficiency, quality, and flexibility. Additive manufacturing (3D printing) is also a technology direction closely related to new quality productivity. It directly manufactures parts based on design models, eliminating complex steps such as mold and tool manufacturing in traditional processing. This not only shortens the product development cycle, but also reduces production costs. The research and application of advanced materials also play an important role in the development of new productive forces. New materials, such as composite materials, high-strength alloys, nanomaterials, etc., are gradually changing the appearance of products with their unique performance advantages. They can improve product performance, extend service life, and reduce weight, providing strong support for the lightweight and high-performance of mechanical products. In addition, green manufacturing and sustainable manufacturing are also important directions of concern in the field of mechanical engineering. Pay attention to environmentally friendly manufacturing methods, such as energy conservation, emission reduction, recycling, and waste management, and make positive contributions to achieving sustainable development and new quality productivity. In the future, with the continuous progress and innovation of technology, the field of mechanical engineering will continue to play an important role, making greater contributions to the improvement of new quality productivity and the sustained development of the economy. Learning to build a platform to support innovation, technological self-reliance and common development. In today's rapidly developing technology, cultivating new productive forces and accelerating the achievement of high-level technological self-reliance and self-improvement are the common goals of the whole society. As a technology community with a long history and significant influence, the Chinese Society of Mechanical Engineering is actively promoting the emergence of new productive forces with its unique advantages, and contributing to the self-reliance and self-improvement of high-level technology. In terms of industry university research cooperation, we are committed to building an efficient cooperation platform, closely linking enterprises, universities, and research institutions, promoting technological innovation, achievement transformation, and industrial upgrading, and providing strong support for the cultivation of new quality productivity. In terms of talent cultivation and exchange, we learn to improve the professional quality of our members and cultivate more innovative and practical talents through organizing technical training, academic seminars, international exchanges and other activities. At the same time, we encourage the interaction of outstanding talents both domestically and internationally, promote knowledge flow, and cultivate high-quality talents for the field of mechanical engineering in China. In terms of technical standards and quality evaluation, we will actively develop professional technical standards, promote technical standardization, and improve the quality and international competitiveness of our products. Actively participate in the formulation of international standards and enhance China's influence and voice on the international stage. In addition, the Chinese Society of Mechanical Engineering also closely monitors the development trends of cutting-edge technologies. Encourage members to actively participate in scientific research projects and promote technological innovation in fields such as artificial intelligence, intelligent manufacturing, and green energy. Faced with the new situation of global technological advancement and manufacturing industry transformation and upgrading, the Chinese Society of Mechanical Engineering has clarified a series of key work directions and goals in its development plan for the next few years, in order to promote intelligent manufacturing, green manufacturing, and sustainable development, and contribute to the upgrading of China's manufacturing industry and technological self-reliance and self-improvement. One is to encourage research and innovation. Learn to support research and innovation in intelligent manufacturing technology, organize cross industry technological forces, and jointly tackle key technological challenges through cross industry technological forces, promoting breakthroughs and development in intelligent manufacturing technology. The second is to promote industrial cooperation. Learn to actively promote industry university research cooperation, build cooperation platforms, and enable enterprises, universities, and research institutions to jointly tackle key issues, form a joint force, and promote the development of intelligent manufacturing technology. The third is to strengthen talent cultivation. Learn to focus on cultivating talents in the fields of intelligent manufacturing and robotics, and improve the quality and ability level of technical personnel through organizing training, seminars, and other activities.
