In China, the medical industry is not only an important branch in the field of big health, but also the top priority of social and people's livelihood development, and it is also a beacon of the capital market. In the long run, due to the huge population size and the accelerated aging process, the demand for medical services is far from saturated. At the same time, the medical industry is developing unevenly. At present, medical and health services are still the mainstay. Rehabilitation services, health management and other services have not yet formed an industrial agglomeration effect, and related industries lack linkage and enjoyment. Mass medical and health resources are abundant, but it has not yet formed an industrial scale in the fields of recuperation and maintenance, health management and technical support services. China has a huge consumer group, and the proportion of aging population is increasing. The health awareness of China people is constantly improving, and the demand for health care products is on the rise. In 20 10, the market size of China health care industry has reached 60.9 billion yuan. At this point, China health food industry began to enter a period of prosperity and development. By 20 16, the market size of health care industry has grown to 295.4 billion yuan, 3.3 times higher than that in 20 10. The aging population has given birth to the continuous development of the pension industry. At the same time, the government has effectively promoted the development of healthy pension industry by promoting policy innovation, optimizing resource allocation and cultivating market players. Nurseries, rehabilitation centers for the elderly, nursing homes and other old-age care institutions have been continuously established and their services have been continuously upgraded. They gradually expanded from general catering, room cleaning and medical treatment to rehabilitation, psychological comfort and entertainment.
