High quality development is the hard truth of the new era. Sun Qiang recently held the Central Economic Work Conference, which deeply summarized and deepened the regular understanding of doing economic work well in the new era through the "Five Musts". Among them, the principle of adhering to high-quality development must be the top priority in the new era. This important statement has issued a new order to promote high-quality development on a new journey, given a new positioning for high-quality development, and pointed out the direction for continuously creating new prospects for the development of the Party and the country, providing fundamental guidance. For the military, it is necessary to transform development concepts, innovate development models, enhance development momentum, effectively accelerate during the window period, and achieve a new leap in combat effectiveness with new development achievements. Development is the key to solving all problems in China and the top priority of the Party's governance and rejuvenation of the country. High quality development is the primary task of comprehensively building a socialist modernized country, and it is the theme of China's economic and social development during the 14th Five Year Plan and beyond. The insistence on high-quality development as the hard principle of the new era is in line with the belief that development is the hard principle, and the sense of urgency and responsibility to move forward with courage is consistent. The new stage of development, new missions and tasks, and new development environment have put forward higher and more urgent requirements for achieving effective improvement in quality and reasonable growth in quantity in the economy. The development of the new era and new stage must be high-quality development, which is an inevitable requirement to follow the law of economic development and maintain sustainable and healthy economic development, as well as an inevitable requirement to effectively prevent and resolve risks and challenges, and comprehensively promote the great rejuvenation of the Chinese nation with Chinese path to modernization. National defense and military modernization, as important components of national modernization, must actively implement the requirements of high-quality development. Now, achieving the centenary goal of building the army has reached a period of hard work and a period of hard work and pressure. We are facing both the heavy task of catching up and leapfrogging, as well as the severe challenge of widening the gap. Slowing development is not enough, and the quality is not high. Whether this established goal can be achieved on schedule largely depends on the transformation of development concepts, innovation of development models, and enhancement of development momentum. Only by consciously promoting high-quality development with a clear understanding of "hard principles", and truly shifting the development model to systematic and connotative development, can we promote the transformation of the quality, efficiency, and driving force of our military construction and development, and continuously improve the quality and efficiency of national defense and military modernization. To promote the high-quality development of our military construction, it is necessary to firmly establish the strategic guidance of "Five More Emphasis". More emphasis is placed on practical combat, innovation driven, system construction, intensive efficiency, and military civilian integration, establishing the strategic guidance for the construction of our military in the new era, clarifying the development direction, driving force, methods, models, and paths. We must fully, accurately, and comprehensively implement the new development concept, resolutely correct all thoughts and behaviors that do not meet the requirements of actual combat, increase the contribution of innovation to the growth of combat effectiveness, enhance the combat capability of our military system, improve the precision of national defense and military development, and consolidate and improve the integrated national strategic system and capabilities. To promote the high-quality development of our military construction, we must adhere to the drive for deepening reform and innovation. Reform and innovation are powerful driving forces for the development of our military, and promoting high-quality development is essential
