Abstract: The role of artificial intelligence technology in the field of elderly care services is becoming more and more significant. At the present stage, the development strategies and policies of AI elderly care service in developed countries outside the region can be discussed from four aspects: development goals, mode classification, key contents and implementation mechanism. In terms of its content, it includes constructing a safe AI elderly care system, practicing the concept of comprehensive care services, focusing on solving ethical and legal dilemmas, and constantly improving the artificial intelligence literacy of citizens. In terms of its implementation mechanism, it includes the government's strong support for the development of intelligent elderly care, and the active participation of enterprises and industry associations. China should learn from the useful experience of foreign AI elderly care strategies, such as the establishment of the elderly as the center of AI elderly care service concept, the formation of diversified fund raising mechanism in the implementation of AI strategy. Specific improvement measures include: adopting smart elderly care strategic mode in line with China's reality, establishing a demand-oriented smart elderly care service supply system, improving the elder's ability to pay for smart elderly care service, and forming a government-led and multi-party participation in smart elderly care governance.
