Initial stage (20 10 years ago): At this stage, the concept of smart pension was introduced, but it is still in the conceptual stage, lacking systematic and large-scale practice. The society's understanding of smart old-age care is limited, and there is a lack of unified standards and policy support.

Pilot promotion stage (20 10 to 20 15): China began to carry out smart pension pilot projects in some places to explore the mode and path of smart pension. The government began to increase the policy inclination of smart pension and promote the development of smart pension.

Vigorous development stage (20 15 to 2020): At this stage, smart pension has received more attention and investment, and the government, enterprises and all sectors of society have actively participated. Smart community for the aged, health monitoring, telemedicine and other projects are constantly emerging, and the coverage is gradually expanding.

Comprehensive popularization stage (2020-present): At this stage, smart pension is no longer limited to pilot or local projects, but has become an important issue of general concern to the whole society. The government has formulated more policies to support smart old-age care, and cooperated in many ways to promote the popularization and application of smart old-age care.

Future prospect stage: The future development will pay more attention to technological innovation, including the wide application of artificial intelligence, Internet of Things, big data, 5G and other technologies, and provide richer, smarter and customized solutions for smart old-age care to meet the diversified needs of the elderly.

The division of these stages reflects the development of smart pension in China. With the changes of society and the progress of science and technology, the smart retirement society will continue to iterate and improve to meet the needs of the elderly.
