Abstract: Against the backdrop of the continuous deepening of global population aging, the silver economy has entered a period of rapid development. After more than a decade of development, China's silver economy has initially formed a multi-level and all-round development pattern. While continuously enriching and improving relevant policies, improving the elderly care service system, creating exemplary elderly friendly communities, deepening the integration of medical care and elderly care, launching the smart and healthy elderly care industry action, and promoting aging friendly transformation from multiple perspectives have become important drivers for the development of the silver economy. In the future development of the silver economy, it is necessary to pay attention to three changes in demand and handle the three pairs of relationships in the development process. [Keywords] Silver economy; population aging In recent years, population aging has become a common problem faced by major economies around the world, and seeking new drivers of economic and social development in the context of aging has become a common exploration for many countries. Over the past decade, significant progress has been made in the development of China's silver economy. On January 15, 2024, the "Opinions of the General Office of the State Council on Developing the Silver Hair Economy and Enhancing the Welfare of the Elderly" (referred to as the "26 Articles on the Silver Hair Economy") was released, becoming the first special document in China named after the "Silver Hair Economy". After the promulgation of the "26 Measures for Silver Hair Economy", local governments and the industry have conducted more intensive explorations on how to promote the development of silver hair economy. These practical explorations have accumulated new momentum for promoting the development of the silver economy. The Third Plenum of the 20th Central Committee of the Communist Party of China emphasized the need to actively address population aging and improve policies and mechanisms for the development of elderly care and the elderly care industry. Developing the silver economy and creating diverse and personalized employment opportunities suitable for the elderly. With the deepening of population aging and the progress of aging, the silver economy will experience even faster development in the future. 1、 The background of the development of the silver economy is that in the long history of human economic development, the silver economy is a new thing. In the 20th century, as more and more countries entered an aging society, the silver economy gradually emerged. Entering the 21st century, population aging continues to deepen globally, and the silver economy has entered a period of rapid development. （1） The development of the silver economy is a historical inevitability of economic and social development. It is manifested by the deepening of population aging and essentially a historical inevitability of economic and social development. The pursuit of health and longevity is an eternal theme of human society, which has become more realistic in the past three hundred years with the improvement of productivity and the advancement of medical technology. The continuously improving living standards and medical technology have enhanced humanity's ability to resist various risks, and the average life expectancy has also achieved significant breakthroughs. In 1990, the world's average life expectancy reached 64 years, with males reaching 61.5 years and females reaching 66.5 years. By 2021, the world's average life expectancy had reached 71 years, with males at 68.4 years and females at 73.8 years. It is expected that by 2050, this number will increase to 77.2 years, with males at 74.8 years and females at 79.8 years. [1] Along with the continuous increase in life expectancy per capita, the advancement of industrialization and urbanization has brought tremendous changes to human production and lifestyle. In 1960, the global population living in cities was 1.018 billion, accounting for 33.60% of the total population. In 2007, the proportion of urban population in the world reached 50.08%, which means that more than half of the population has moved to urban areas. By 2023, the global urban population will reach 4.6 billion, accounting for 57.34% of the total global population. [2] The development of industrialization and urbanization has greatly changed the way humans produce and live. In the new environment, the rise of socialized services has led to the weakening of family functions. At the same time, the acquisition of women's right to education, the improvement of educational level, the transformation of social values, and the fast-paced work style have led to a shift in the overall population development trajectory from "high birth, high death, and low growth" to "low birth, low death, and low growth". The crude birth rate of the world population has been declining from 31.91 ‰ in 1960 to 16.65 ‰ in 2022. [3] The increase in life expectancy and the continuous decline in birth rates have brought about changes in the age structure of the population. According to the commonly used definition of aging in the international community, France entered an aging society in 1864, becoming the first country in human history to do so. In 2002, the proportion of people aged 65 and above in the global population reached 7.07%, indicating that the world has entered an aging society. In 2023, the proportion of elderly people aged 65 and above in the global population reached 10.03%. [4] Based on the current development trend, the decline in birth rate and the increase in life expectancy per capita are still two major trends that are likely to continue in the future, and global population aging will also further develop. In January 2023, the United Nations Department of Economic and Social Affairs released the World Social Report 2023: Leave No One Behind in an Aging World. The report clearly states that population aging has become a prominent global trend in today's era. By 2050, the global population aged 65 and above will reach 1.6 billion, accounting for over 16% of the total population. [5] Population is a fundamental element of economic and social development. The factor of labor has been given an important position since the initial research of economics. But the impact of population on economic and social development far exceeds analysis solely from the perspective of labor force. The ultimate goal of social development is to better serve the people in society and make human life better. Human needs largely determine the direction of various economic activities in society. As a collection of individuals, the changes in population development undoubtedly directly affect economic development. As the average life expectancy continues to increase, more attention needs to be given to the elderly stage of the life cycle. How to better meet the various needs of the elderly, elderly families, and the elderly stage will inevitably become an important aspect to consider in economic activities. On the contrary, the development of products and services targeting the needs of the elderly and the elderly stage, as well as the various preparations made, will inevitably become a new engine of economic growth in a society where the scale of the elderly continues to grow. With the deepening of aging population, the importance of this engine will become more prominent. Overall, it can be concluded that the silver haired economy is fundamentally a result of economic and social development. Actively developing the silver economy has also become a rational choice for all countries after entering an aging society. In practice, the development of silver economy in various countries is not achieved overnight, but gradually developed through the continuous improvement of aging systems and the continuous improvement of elderly care service systems. In the early stages of development, countries also continuously promote relevant explorations from the perspective of actively promoting the development of the aging industry. Internationally, countries and regions such as the United States, Europe, and Japan have formed different experiences in their development. In 1935, the United States enacted the Social Security Act, marking the beginning of the establishment of the American elderly care system. Subsequently, socialized elderly care services were provided through market means, and services such as community care, home care, and nursing homes were developed successively. In Europe, since the 1950s, with the establishment and improvement of modern welfare state systems, major countries have gradually shifted from government led elderly care service supply to socialized elderly care services provided by multiple entities such as government, enterprises, and society. Some countries have promoted the rapid development of the elderly care service industry through industrialization, and have produced influential elderly care service brands in Europe and even the world. Japan entered an aging society in 1970. In June 1986, the Japan Ministry of Health, Labour and Welfare's Aging Response to New Civil Vitality Revitalization Research Association released the "Silver Hair Industry Revitalization Research Report". [6] The report analyzed the necessity of developing the silver economy, predicted the silver market, analyzed the characteristics and needs of the elderly, and analyzed the current situation and problems faced by the silver industry. Regarding the necessity of developing the silver hair industry, the report clearly states that from an economic perspective, the elderly are the bearers of expanding domestic demand, and incorporating them into the economic cycle is indispensable for Japan's economic development. Activating the silver hair market is an important issue for the Japanese economy and a crucial factor in driving economic growth through expanding domestic demand. In the following decades of development, the development of Japan's silver economy was fully launched. While actively cultivating products and services for the elderly, the long-term care insurance implemented in 2000 leveraged more market forces to enter the silver economy field, becoming a powerful means of promoting the development of the silver economy. （2） The development process and conceptual definition of China's silver economy can be traced back to the 1980s, which is the origin of the practical development of China's silver economy. With the implementation of reform and opening up, China has put forward the idea of "socialization of social welfare" in the field of elderly care services, which means changing the previous government's practice of providing a single source of welfare and attempting to promote the development of social welfare, including elderly care services, in a socialized manner. However, given the large number of children in the family at that time and the fact that elderly care was mainly undertaken by the children, the idea of raising children to support the elderly was deeply rooted, and the whole society did not pay high attention to socialized elderly care. In addition, the overall economy is still in a period of "shortage economy", and the supply of products and services for the elderly in society is not yet abundant. The development of the silver haired economy is in its infancy. In 2000, China entered an aging society, and the whole society's attention to elderly care issues further increased. At the same time, the shrinking of family size has also led to the weakening of the elderly care function of families, and the attention of the whole society to the development of elderly care services in a socialized manner has further increased. In February 2000, the General Office of the State Council forwarded the "Opinions on Accelerating the Socialization of Social Welfare" jointly formulated by the Ministry of Civil Affairs and 11 other departments, accelerating the development of social welfare, including elderly care services. On September 13, 2013, the State Council issued several opinions on accelerating the development of the elderly care service industry, proposing six main tasks and six policy measures to promote the development of elderly care services from an industrial perspective. Taking this as an opportunity, with the continuous increase in social attention to elderly care and the further increase in family dependence on socialized elderly care services, China's elderly care service industry has entered the fast lane of development. While actively promoting industrial practice, the academic community has gradually increased its research and exploration on the development of the silver economy. In 2012, Beijing held the first International Aging Industry Expo, marking the beginning of presenting the progress of the elderly care industry in China through exhibitions. As a background report for this expo, the "2012 Beijing Aging Industry Research Report" has been released. As the first specialized study named after a research report on the aging industry in China, the research team has sorted out the definitions of the four types of aging industries that have existed so far based on literature review. On this basis, the aging industry is defined as "not an independent physical industry sector in the traditional sense, but a comprehensive industrial system that includes different physical industries. It is an industry divided by age and age determined consumption characteristics, including all goods production and services related to the material and spiritual needs of the elderly and other special needs". In defining the extension of the aging industry, the report divides the aging industry into seven categories based on the current development status: physical examination industry, health products industry, nursing products industry, tourism industry, education and training industry, financial management industry, and nursing service industry. Based on questionnaire surveys and industry case studies targeting the elderly, the report analyzes the supply and demand status of the aging industry development. In international communication
