Recognize the significance of the era of building a war-oriented national defense mobilization. The world is undergoing major changes that have not been seen in a century. The linkage, suddenness and variability of strategic risks are enhanced. National defense mobilization must focus on "war", transform and innovate around the mission and task, strengthen the efficiency, sensitivity and continuous transformation capabilities, and provide excellent mobilization support for defeating and winning the enemy. The objective need to win the new hybrid war. In recent years, the hybrid war is moving from theoretical creation to practical breakthrough, and has become a powerful lever to change the geostrategic pattern and even pry the world's great changes. In the context of the more complex international situation, the rivalry between the enemy and ourselves in the future war will not only cover the traditional fields such as military, political, economic, scientific and technological fields, but also further penetrate and expand into the cognitive and social fields. Various confrontations are intertwined, mixed and conducted, and the overall national security needs more comprehensive operational planning and system layout. As a bridge between the military and the civilian, national defense mobilization has a unique advantage in excavating and mobilizing talents, technology and industrial resources in all fields of society to serve the war. To win the future war with the characteristics of multi-domain linkage and cross-domain coordination, it is urgent to build a full-spectrum and full-dimension war-type national defense mobilization. The effective support of preemptive game control. In the future war, the high-tech group represented by artificial intelligence is the prerequisite for the formation of perception advantage, decision-making advantage, accusation advantage and action advantage.

The war-oriented national defense mobilization with new demand as the traction, new technology as the focus and new capabilities as the core can rapidly transform high-tech into advanced combat effectiveness, thus releasing huge potential and supporting the battle for the commanding heights of the future battlefield game. An important way to exert the power of the people's war. The People's War is the product of the combination of Marxism and the practice of China's revolutionary war, and is the magic weapon of our army to overcome the enemy and win. In today's world, with the deepening of military reform and the accelerated evolution of war forms, the manifestations, application scope and coverage of people's war have also been developing.
