Population aging brings challenges and opportunities for economic and social development, and developing the silver economy is an important means to promote the well-being of the seniors, actively respond to population aging, and promote high-quality economic and social development. Currently, China's market regarding the aging population presents the trends of an increasing scale of demand subjects, transformation and upgrading of the demand structure, and highlighting of personalized and digital demand, and faces prominent challenges including insufficient supply of products and services dedicated for the seniors, lack of technological and financial support, and inadequate policies and standards systems. This study summarizes the international experience in developing the silver economy to cope with population aging, i.e., emphasizing the application of science and technologies and smart senior care, improving the supply of products and services for the seniors, promoting technological and financial support, and improving policy designs and relevant standards. On this basis, we propose the following countermeasures to promote the development of China's silver economy: (1) strengthening the research and application of engineering science and technologies to respond to market demand, (2) optimizing the supply of products and services for the seniors to balance supply and demand, (3) developing aging-adapted technologies and pension finance to stimulate market vitality, and (4) improving policy designs and relevant standards to ensure orderly development.
