In October, in the warm atmosphere of welcoming the 20th National Congress of the Communist Party of China (CPC), the Chinese People's Revolutionary Military Museum and the exhibition hall of "Leading a Strong Army to Revival - Exhibition of Achievements in National Defense and Military Construction in the New Era" were full of visitors. In front of the weapons and equipment model in the exhibition area of "Sharpening sword and casting shield towards first-class", people took photos and punched cards one after another. The theme of this exhibition area is "Deeply promote science and technology to strengthen the military". Back five years ago, at the "Five Years of Striving" large-scale achievement exhibition in Beijing Exhibition Hall, the theme model booth named "A Strong Military Journey and Sailing" also attracted much attention. Since the 18th National Congress of the Communist Party of China, the hard core achievements of national defense scientific and technological innovation have been intensively displayed here. The two booths across time and space, like two shining coordinates, record the sonorous steps taken and the shining footprints left by the modernization of our military weapons and equipment. On the journey of building a strong military, President Xi made the important conclusion that science and technology are the core combat effectiveness, and issued the order of the times to build an innovative people's army. Standing at the strategic height of the overall situation, President Xi Jinping 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 lit a strong engine for building a strong military. On the first working day of 2022, President Xi Jinping issued a training mobilization order to the whole army. "Keep an eye on the changes in science and technology", "vigorously promote scientific training"... All officers and men in the army follow orders and move forward bravely in the direction of the commander. Building a strong military through science and technology is a grand strategy for the future and a clarion call for a new journey. In the great practice of building a strong military through science and technology, the people's army will continue to write a new chapter of the times and radiate a new style of the times. Driven by innovation, the Party has gathered surging forces to build a strong military through science and technology. In November 2021, the Sixth Plenary Session of the 19th CPC Central Committee deliberated and passed a special "centennial summary" - the Resolution of the CPC Central Committee on the Party's centennial achievements and historical experience. Among them, "Insisting on the implementation of innovation driven development strategy" stands out. Innovation driven is a "new word" if viewed from the perspective of 100 years of history; However, it is a "hot word" to observe the time category of these 10 years. Since the 18th National Congress of the Communist Party of China (CPC), President Xi has repeatedly stressed on many occasions that "the development of defense science and technology and weapons and equipment must shift to innovation driven development", "putting innovation in an important position in the overall construction and development of our military", "giving full play to the role of innovation driven development and cultivating new growth points of combat effectiveness"... Why is innovation driven so prominent? In the face of changes in the world, times and history, President Xi pointed out that today's world is undergoing unprecedented changes in a century, and scientific and technological innovation is one of the key variables. The new round of scientific and technological revolution and military revolution are changing with each passing day. Whether we can seize the opportunity and seize the momentum to win the initiative and occupy the commanding heights in the field of national defense scientific and technological innovation is related to the success or failure of the game of big countries and the rise and fall of big countries' armies. We must clearly see that our original innovation ability is not strong, the overall efficiency of the innovation system is not high, the integration of scientific and technological innovation resources is not enough, and the distribution of scientific and technological innovation forces needs to be optimized... In this regard, President Xi clearly pointed out that we must enhance our sense of urgency and promote scientific and technological innovation and progress with greater determination and strength.
