The new development concept originates from development practice, and to continuously deepen its theoretical research and development in practice is a constantly changing process. The development environment and conditions will not remain unchanged, and the development concept will naturally not remain unchanged. Since the 18th National Congress of the Communist Party of China, our party has made scientific judgments on the economic situation, proposed many major theories and concepts for economic and social development, and made timely adjustments to development concepts and ideas. Among them, the new development concept is the most important and important, with distinct practicality and timeliness. The Fifth Plenary Session of the 18th Central Committee of the Communist Party of China proposed: "To solve development problems and cultivate development advantages, we must firmly establish and effectively implement the development concept of innovation, coordination, green, openness, and sharing. This is a profound change that affects the overall development of our country." The Fifth Plenary Session of the 19th Central Committee of the Communist Party of China clearly defined "adhering to the new development concept" as a principle that must be followed in economic and social development during the 14th Five Year Plan period. The report of the 20th National Congress of the Communist Party of China proposes that "implementing the new development concept is the only way for China's development and growth in the new era". Our party's judgments and expressions on the new development concept are constantly enriching and developing, reflecting our deepening understanding and understanding of the new development concept in the interaction between theory and practice. From a theoretical perspective, the new development concept is not derived from nothing, but is formed on the basis of a profound summary of domestic and foreign development experiences and lessons, and also on the basis of a profound analysis of the overall development trend at home and abroad. It answers a series of theoretical and practical questions about the purpose, motivation, methods, paths, and other aspects of development, and is a systematic theoretical system. As our party continues to promote the sinicization and modernization of Marxist political economy, elevating practical experience into a systematic scientific theory, our understanding and understanding of new development concepts will also continue to deepen. From a practical perspective, the new development concept is formed in response to the phased changes in China's economic and social development
