1. Coping with the problem of population loss and labor costSummary: Unmanned technologies such as unmanned aircraft, unmanned driving, unmanned shops, unmanned hotels and unmanned banks have great potential and have many points of convergence with the needs of economic development in Northeast China. Despite the challenges of technology adaptation to the environment, market awareness and talent reserve in the process of helping the economic development in Northeast China, unmanned technology can become a powerful driving force to promote the economic development in Northeast China and provide new development opportunities for the revitalization of the old industrial bases in Northeast China as long as active coping strategies are adopted, such as optimizing technology, strengthening publicity and talent training.1.

UAV has become an indispensable scientific and technological force in modern society. In agriculture, as an important agricultural producing area in China, the application prospect of UAV is broad. It can carry out accurate pesticide spraying and crop growth monitoring. For example, in a large paddy field in Northeast China, drones can spray pesticides evenly according to the set route. Compared with traditional manual spraying, it is not only more efficient, but also can reduce pesticide waste and improve the quality of agricultural products. According to the statistics of agricultural departments, using drones for plant protection operations can improve the efficiency by 5-10 times compared with traditional methods. In the field of geographic mapping, UAV can quickly obtain detailed data of complex terrain in Northeast China, and provide accurate maps and data support for urban planning, resource exploration and other work.1. Technology adapts to the challenges of the special environment in Northeast China.
