To strengthen the country and the army, science and technology should be the first. Science and technology are the most active and revolutionary factor in military development. In recent days, strengthening national defense scientific and technological innovation has become a hot topic of discussion among the military representatives. On the journey of building a strong military, President Xi Jinping made a major assertion that science and technology is the core combat power, and issued the era order of building an innovative people's army. President Xi stood at the strategic height of the overall situation, comprehensively implemented the strategy of building a strong military through science and technology, created a grand blueprint for scientific and technological innovation for the people's army, and ignited a powerful engine for the great cause of building a strong military. Representatives of the military have said that they should aim at the forefront of military science and technology in the world, promote major technological innovation and independent innovation, truly grasp the core technology in their own hands, accelerate the transformation of science and technology to combat effectiveness, and provide strategic support for achieving the centennial goal of building the military as scheduled. The core battle force is science and technology. In today's world, science and technology are showing a fission-type development trend, and the speed, breadth and depth of its application in the military field are unprecedented. Science and technology have never had such a profound impact on national security and the overall military strategy as today, and have never had such a profound impact on the construction and development of our military. The representative members of the military believed that we should adhere to the need for combat effectiveness and victory in scientific and technological innovation, and promote the transformation of our military construction to quality, efficiency and technology-intensive. In recent years, the construction of domestic aircraft carriers, new nuclear submarines, large destroyers and other "weapons of great power" has been reported frequently. The Yun-20, J-20 and other advanced fighter planes have been installed in succession. The Dongfeng series of new strategic missiles have made a stunning debut... "This fully reflects the overall leap in China's defense science and technology. What is needed in the battlefield, what is needed in the war, where is the baton of scientific and technological innovation." Gu Qingyue said, "Science and technology can only play a strong leading role in the growth of combat effectiveness, and can only become a real combat effectiveness if it is correctly applied to military practice. Military science and technology workers should bear in mind the mission and responsibility of fighting for the army, promote the accurate docking of the supply side of science and technology and the demand side of fighting, and accelerate the contribution rate of improving the combat effectiveness of science and technology services." The new round of scientific and technological revolution and military revolution are changing with each passing day. Can we seize the opportunity and seize the momentum, Winning the initiative and occupying the commanding heights in the field of national defense science and technology innovation is related to the success or failure of the game between the big countries and the rise and fall of the military forces of the big countries. "We should not only take the 'free ride' of national scientific and technological innovation, but also better stimulate the 'power source' of military scientific and technological innovation." Liang Xiaojing said that only with a sense of urgency that can't wait, step up the formation of unique advantages in the areas of strategic competition, and constantly improve the content of scientific and technological innovation, can we transform scientific and technological advantages into ability advantages and victory advantages. Those who observe the situation are wise, and those who control the situation win. The military representative members said that the smooth implementation of the "Fourteenth Five-Year Plan", the high-quality promotion of the cause of building a strong military in the new era, and the realization of the centennial goal of building a military need more scientific and technological solutions than ever before, and the need to comprehensively implement the strategy of building a strong military through science and technology. Only by accelerating the transformation of science and technology to combat effectiveness can we keep up with the pace of the times and win the initiative and provide strong scientific and technological support for the realization of the Chinese dream of building a strong military. At present, the competition of military power is increasingly manifested in the competition of innovation ability. We can't do without innovation, nor can we slow down innovation. "If we don't take the initiative to recognize change
