Recently, China has achieved a new harvest of scientific and technological achievements in multiple fields. On May 28th, the C919 domestic large passenger aircraft successfully completed its commercial maiden flight; On May 30th, the Long March 2F Yao 16 carrier rocket successfully launched the Shenzhou 16 manned spacecraft, marking the first manned flight mission in the application and development phase of the space station; The 2023 Zhongguancun Forum released 10 major technological achievements, including the new generation 256 core blockchain dedicated acceleration chip and the new generation quantum computing cloud platform. Technological self-reliance and self-improvement are the foundation of national strength and the key to security. Looking back at the history of over 70 years since the establishment of the People's Republic of China, the main line of fully developing technology, supporting economic construction, and safeguarding national security has always been running through it. In the 1950s and 1960s, in a complex international situation, in order to defend national security and maintain world peace, we decisively made the strategic decision to independently develop the "two bombs and one satellite", and ultimately achieved success. The "Two Bombs and One Satellite" strategy has enhanced China's international status and influence, effectively safeguarding China's national security, enhancing national cohesion, greatly promoting economic development, and promoting the overall level of science and technology in the country. Nowadays, space exploration has become a new technological competition point for countries around the world, and China's space station has been officially completed and entered the stage of application and development. Once again, China has taken the lead in the global aerospace technology competition. Technological self-reliance and self-improvement cannot be separated from the development of technological innovation, which is a strategic support for improving social productivity and comprehensive national strength. Implementing the innovation driven development strategy is a fundamental measure to accelerate the transformation of economic development mode, solve deep-seated contradictions and problems in economic development, and enhance the endogenous driving force of economic development. Aerospace technology is highly advanced, but many technological achievements derived from it are closely related to the daily lives of the people. Technologies such as dehydrated vegetables and nuclear magnetic resonance imaging are classic achievements in the transformation of aerospace technology into civilian use. The newly launched domestic large passenger aircraft C919 is also the latest successful case of China's technological transformation. As the pearl on the crown of modern industry, if a country wants to develop a airliner with independent intellectual property rights, it not only needs to have a perfect industrial manufacturing capacity, but also needs to have a complete upstream and downstream industrial chain, all of which need strong social productivity and comprehensive national strength as support. The successful maiden flight of the C919 domestically produced large passenger aircraft is a vivid practice of innovation as the primary driving force for development. It will also effectively promote the long-term development of the country's economy and society through the trillion yuan civil aviation market in China, and will greatly inspire China's scientific and technological workers to continue to make contributions and create brilliance. If technology is strong, the nation will be strong, and if technology is strong, the country will be strong. High quality development is the primary task of comprehensively building a socialist modernized country. Accelerating the construction of a technological powerhouse and achieving high-level technological self-reliance and self-improvement will inevitably lead the giant ship China along the path of high-quality development, riding the wind and waves, and heading towards a better tomorrow.
