Today's China needs high-quality development. Internally speaking, as China's reform and opening up enters a deep stage, the main contradiction in our society is the contradiction between the growing needs of the people for a better life and the unbalanced and insufficient development. High quality development is a development that enhances people's livelihood and happiness, and is an inevitable choice to solve the main social contradictions in the new stage of development. Externally speaking, China is currently undergoing a period of accelerated evolution in a century of changes. The international situation is complex and ever-changing. Only through high-quality development, accelerating the construction of a modern economic system, enhancing the security and stability of development, and continuously enhancing the country's comprehensive competitiveness, can China effectively face external shocks and challenges, better unify domestic development with opening up, and connect China's development with world development, Integrate the interests of the Chinese people with the common interests of people from all over the world. Implementing the new development concept is an inherent requirement for high-quality development. We should take innovation as the primary driving force for high-quality development, promote industrial upgrading through innovation, and drive economic development. Taking coordination as the endogenous characteristic of high-quality development, we adhere to deepening supply side structural reform and focusing on expanding effective demand for coordinated development. Taking green as the universal form of high-quality development, implementing the development concept of "green mountains and clear waters are invaluable assets", promoting the coordination between economic growth and environmental protection, and making development more sustainable. Taking openness as the necessary path for high-quality development, continuing to deepen reforms, and promoting high-quality development through high-level openness. Taking sharing as the fundamental goal of high-quality development, practicing the purpose of development for the people, and making the achievements of development more and better benefit all the people. Building a new development pattern is the path to achieving high-quality development. Accelerate the construction of a new development pattern with domestic circulation as the main body and domestic and international dual circulation promoting each other. On the one hand, building a standardized and efficient national unified market, breaking down various forms of local protection and market segmentation, promoting the reasonable flow of labor, capital, land, intellectual property and other factors across the country, unblocking development bottlenecks, ensuring smooth operation of the upstream and downstream markets, leveraging the advantages of large markets and production capacity, continuously releasing endogenous driving forces, and unblocking the domestic circulation. On the other hand, we will continue to expand high-level opening-up to the outside world, cultivate new drivers of foreign trade, relax market access for industries such as telecommunications and healthcare, create a first-class business environment that is market-oriented, legal, and internationalized, promote the integration of domestic and international rules, and actively participate in international circulation. Through the joint drive of domestic circulation and international circulation, we aim to promote the organic combination of effective improvement in quality and reasonable growth in quantity in economic development. Developing new productive forces is the driving force behind high-quality development. To lead the formation of new productive forces through technological innovation, accelerate the layout of new technologies, industries, formats, and tracks, and achieve high-quality, efficient, and efficient development of productive forces. In strategic areas such as information technology, biotechnology, new energy, aerospace, and green environmental protection
