1. Technology adapts to the challenges of the special environment in Northeast China.Summary: 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.Northeast China is facing the problem of population loss in recent years. Although the labor cost has been relatively reduced, the shortage of labor still exists in some industries. The application of unmanned technology can make up for the shortage of manpower to some extent. For example, in some remote forest areas or mining areas, drones can carry out security patrols, environmental monitoring and other work to reduce dependence on manpower. Unmanned shops and banks can be laid out in towns with relatively small population and provide basic commercial and financial services without a lot of human support.

In the northeast, people's market awareness of unmanned technology may be relatively insufficient, and related professionals are also scarce. In order to improve market awareness, extensive publicity and promotion activities can be carried out, such as holding unmanned technology exhibitions and technical lectures. In terms of talent reserve, universities and vocational colleges in Northeast China can cooperate with enterprises to set up professional courses related to unmanned technology, cultivate technical talents to meet local needs, and attract foreign talents to flow into Northeast China to provide intellectual support for the development of unmanned technology in Northeast China.Second, the demand for economic development in Northeast China and the opportunity for unmanned technology to meetUAV 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.

Third, the challenges faced by unmanned technology to help the economic development in Northeast China and the countermeasures to break the situation2. Driverless driving: the pioneer of traffic changeUnmanned shops, hotels and banks are emerging business service models. Unmanned stores adopt advanced automation equipment and intelligent identification technology, so customers can choose and buy goods and complete the settlement without manual cashier. In some business districts in Northeast China, unmanned stores can reduce operating costs and improve shopping experience. Unmanned hotels provide convenient accommodation services through smart door locks and self-service check-in systems. Northeast China is a region rich in tourism resources. Unmanned hotels can meet the needs of tourists at different times and improve the operational efficiency of hotels. Unmanned banks provide customers with self-service financial services, such as account opening, transfer and wealth management, which is convenient for people in Northeast China to handle financial affairs, and can also improve the service efficiency of banks and the flexibility of network layout.
