The speech reviews and summarizes the fruitful achievements made by the Party Central Committee in promoting high-quality development since the new era, objectively analyzes the factors that constrain high-quality development, and comprehensively elucidates the practical significance, method paths, and important measures of accelerating the development of new productive forces to promote high-quality development. The new journey of national rejuvenation provides scientific guidance for promoting high-quality development. Theory originates from practice and guides practice. Productivity is the most active and revolutionary element that drives social progress. High quality development requires new productivity theories to guide, and new quality productivity has already formed and demonstrated strong driving and supporting forces for high-quality development in practice. We need to summarize and generalize from a theoretical perspective to guide new development practices. In summary, new productive forces play a leading role in innovation, breaking away from traditional economic growth methods and development paths of productive forces. They possess high-tech, high-efficiency, and high-quality characteristics, and are in line with the advanced productive forces of the new development concept. It is born out of revolutionary technological breakthroughs, innovative allocation of production factors, and deep industrial transformation and upgrading. Its basic connotation is the leap of workers, labor materials, labor objects, and their optimized combinations, with a significant increase in total factor productivity as the core symbol. Its characteristic is innovation, the key is quality, and its essence is advanced productivity. We must deeply recognize that accelerating the development of new quality productive forces is an objective requirement for shaping new driving forces and advantages of development, and is an inevitable choice for building new advantages of development and winning the initiative of development. Only by deeply grasping the era's connotation, core essence, and essential requirements of new quality productive forces can we implement the requirements for accelerating the development of new quality productive forces with a more forward-looking strategic vision, more effective practical measures, and more proactive actions. To accelerate the development of new quality productive forces, we must firmly grasp the bull's nose of technological innovation. Technology is the primary productive force, and innovation is the primary driving force for development. Technological innovation can give birth to new industries, new models, and new driving forces, which are the core elements for developing new quality productive forces. Throughout recent years, the new engines of global economic growth have all been brought about by new technologies, leading to the formation of new productive forces. To accelerate the development of new quality productive forces, we must firmly adhere to innovation and not relax, and constantly make up for shortcomings, strengthen the foundation, and forge the long board. On the one hand, it is necessary to strengthen technological innovation, especially original and disruptive technological innovation, accelerate the realization of high-level technological self-reliance and self-improvement, win the battle for key core technologies, and enable original and disruptive technological innovation achievements to emerge in a competitive manner, cultivating new driving forces for the development of new quality productive forces. On the other hand
