The ever-deepening population aging has brought considerable challenges and pressures to elderly care service system in China. European countries such as Sweden，the Netherlands，Switzerland，Denmark，and Iceland have generally established a relatively mature elderly care service system consisting of effective policy packages to clarify the main body of responsibility in elderly care services for all levels of government，the sophisticated financing mechanism that mainly depends on government finance or government-led social insurance or both，and the provided system for elderly service with strict access mechanism，diversified content and age-appropriate form which is meanwhile equipped with a service quality supervision and evaluation mechanism. In addition，a research trend in technological innovations of nursing services and social interaction has been seen in the field of elderly care. All above enlighten that in the process of building a more complete and in-depth elderly care service system，China should focus on optimizing the top-level design of it，keeping up with the times，integrating the supply of elderly care services，and attaching importance to the new technologies for elderly care in nursing and social services.
