General Secretary Xi Jinping attaches great importance to the development of the real economy, which is reflected in multiple works in the first volume of "Selected Works of Xi Jinping's Economy". General Secretary Xi Jinping pointed out in "Focusing on Revitalizing the Real Economy" that "no matter when the economy develops, the real economy is the foundation for China's economic development and for us to win the initiative in international economic competition; In the report of the 19th National Congress of the Communist Party of China, it was proposed that the focus of economic development must be placed on the real economy; In the report of the 20th National Congress of the Communist Party of China, it was emphasized to "adhere to the focus of economic development on the real economy, promote new industrialization, accelerate the construction of a manufacturing power, quality power, aerospace power, transportation power, network power, and digital China". These important statements have pointed out the direction for building a strong material and technological foundation for Chinese path to modernization, and have great theoretical and practical significance. We should learn and understand them in depth. In the new era, China's economy has shifted from a stage of high-speed growth to a stage of high-quality development. To promote high-quality economic development, we must adhere to deepening the supply side structural reform and focus on expanding effective demand synergy, coordinate the relationship between total supply and total demand, and achieve a new dynamic equilibrium of supply and demand at a higher level. General Secretary Xi Jinping deeply analyzed the prominent contradictions and problems faced by China's economic operation at the 2016 Central Economic Work Conference, pointing out the "three major imbalances" of structural supply-demand imbalance in the real economy, financial and real economy imbalance, and real estate and real economy imbalance. He emphasized that "revitalizing the real economy is the main task of supply side structural reform, and supply side structural reform should focus on revitalizing the real economy". On the one hand, we must focus on comprehensively improving the quality of products and services, which is the central task of enhancing the supply system. We should make good use of innovation, which is the winning weapon for the development of physical industries, and make good use of both international and domestic markets and resources. We should attach importance to optimizing industrial organization. On the other hand, it is necessary to handle the relationship between finance and the real economy well, and comprehensively improve the efficiency and level of finance serving the real economy. General Secretary Xi Jinping emphasized in "Serving the Real Economy and Preventing Financial Risks" that "the real economy is the foundation of finance, and finance is the lifeblood of the real economy. Serving the real economy is the duty and purpose of finance. To optimize the financing structure system and create a financial chain that adapts to the development of the real economy, we must not deviate from reality to virtuality. Put the high-quality development of the manufacturing industry in a more prominent position. Manufacturing is the foundation of a country and a strong nation, an important component of the real economy, and a core industry carrier for modern technological innovation. The high-quality development of manufacturing industry is of paramount importance to the high-quality development of China's economy. In the new era and new journey, the key task is to comprehensively promote the construction of a powerful country and the rejuvenation of the nation with Chinese path to modernization, and to realize new industrialization. This requires promoting high-quality development of the manufacturing industry and achieving the transformation of China from a manufacturing powerhouse to a manufacturing powerhouse. General Secretary Xi Jinping proposed in "Promoting High Quality Development of Manufacturing Industry" that "the Central Committee of the Communist Party of China has made arrangements to improve the quality of manufacturing industry and the innovation capability of key core technologies. We must firmly grasp the green mountains and not relax, and effectively implement them. Efforts should be made to enhance the innovation capability of the manufacturing industry, with intelligent manufacturing and green manufacturing as the main focus, accelerating the development of advanced manufacturing, continuously promoting the optimization and upgrading of the manufacturing industry towards high-end, intelligent, green, and integrated directions, improving the basic capabilities of the industry and the modernization level of the industrial chain, and comprehensively building an independent, controllable, safe, and reliable industrial chain supply chain. Build a modern industrial system supported by the real economy. The 20th National Congress of the Communist Party of China has outlined a grand blueprint for comprehensively building a socialist modernized strong country, aiming to establish a modern economic system by 2035. The focus of economic development must be placed on the real economy, with improving the quality of the supply system as the main direction, accelerating the construction of a modern industrial system supported by the real economy, and providing a carrier for cultivating and developing new quality productive forces. It is necessary to realize the coordinated development of the real economy, scientific and technological innovation, modern finance and human resources, promote the deep integration of scientific and technological innovation and industrial innovation, promote the deep integration of the digital economy and the real economy, promote the deep integration of modern service industry with advanced manufacturing industry and modern agriculture, transform and upgrade traditional industries, cultivate and expand emerging industries, layout and build future industries, build a modern infrastructure system, and improve the integrity, progressiveness and security level of the industrial system.
