At present, China is building a modern socialist country in an all-round way, making the goal of the 200th year into a new journey, and has more confidence and ability to achieve the goal of the great rejuvenation of the Chinese nation than at any time in history. To achieve this goal, we must adhere to the principle that technology is the first productive force, talent is the first resource, and innovation is the first power. Take scientific and technological self-reliance as the foundation and strategic support of China's modernization drive, open up new ways to develop new fields, and constantly shape new advantages of new impetus for development.
（1） Achieving high-level scientific and technological self-reliance is the strategic basis for national prosperity and national rejuvenation. Throughout the history of human development, innovation has always been an important factor in the development of a country and a nation and the promotion of productivity. Scientific and technological innovation is one of the most important variables in a hundred years. Major countries have taken scientific and technological innovation as the main battlefield of the international strategic game. The competition around the peak of science and technology is unprecedented fierce. Who holds the "ox nose" of scientific and technological innovation, who takes the first hand of scientific and technological innovation, who starts first, who starts first, can you win the advantage. On the contrary, it will bring about the attenuation of development impetus and the ceiling of capability. In the new journey of the new era, we must insist on putting the development of the country and the nation on the basis of our own strength, and fully understand the decisive significance of achieving high-level scientific and technological independence for enhancing the competitiveness and sustainability of China's development. Scientific and technological self-reliance is not only a development issue, but also a survival issue. The "strong bones" of high-level scientific and technological self-reliance support the great cause of national rejuvenation. This is an inevitable choice for the future and the only choice.
（2） Achieving a high level of scientific and technological self-reliance is an inevitable choice to cope with risks and challenges and safeguard national interests. At present, the international environment is complex, the world economy is in a downturn, the supply chain of the world industrial chain is facing restructuring, and the instability and uncertainty are significantly increasing. The world has entered a new round of turbulent transformation. The impact of COVID-19 and Ukraine crisis on the world shows that high level scientific and technological self-reliance has important strategic and overall significance. To effectively respond to the major challenges ahead, guard against major risks, and safeguard national security and strategic interests, we should firmly grasp the foundation and security path of national prosperity of scientific and technological independence, constantly improve the independence, independence, and security of China's development, improve the ability to resist pressure, change, hedge, and strengthen the ability to counter the system. China's scientific and technological development is at a critical stage of being strong or weak, or failing to advance or retreat. Only by accelerating high-level scientific and technological self-reliance and firmly holding the initiative of development in our own hands can China's modernization process not fall behind or be interrupted.
（3） Achieving high-level scientific and technological self-reliance is the essential requirement for implementing the new development concept, building a new development pattern and promoting high-quality development. The new journey of the new era, the implementation of the new development concept, the construction of the new development pattern, and the promotion of high-quality development need more scientific and technological solutions than ever before, and need to strengthen the first impetus of innovation. Achieving a high level of scientific and technological independence is the need to build a new development pattern. It is necessary to promote the domestic circulation with scientific and technological independence, improve the quality and level of the supply system, create new demand with new supply, and ensure the safety and stability of the industrial chain supply chain by unblocking the domestic and international double circulation with scientific and technological independence. Achieving high-level scientific and technological self-reliance is the need to promote high-quality development. Supported by strong science and technology, we will promote the construction of a modern economic system with qualitative, efficient and dynamic changes. Achieving a high level of scientific and technological self-reliance is the need to achieve a high quality of life for the people. More scientific and technological innovation achievements related to people's livelihood should be launched, and efforts should be made to solve the problem of unbalanced and inadequate development, so as to meet the people's desire for a better life. Only by achieving a high level of scientific and technological self-reliance can we build a new development pattern, provide new growth space, important focus and main support system for promoting high-quality development, and make high-quality development that implements the new development concept more dependent on innovation-driven connotative growth.
