Abstract: The supporting system of rural left-behind elderly includes self-support based on farming or livestock raising，descendant-support based on younger generations，and social-support based on welfare system. “Home care”is still the most popular old-age care model that fits in the needs of left- behind elderly in rural China. At present，the base of“home care”relying on self and descendant support is declining gradually，while social support is still quite limited. Through redefining the social role of left-behind elderly，we found that they are not“wasted lives”，but important foundations for the countryside. The supporting system of rural left-behind elderly should include a welfare system based on the concept of“sharing”which helps them obtain the deserved part from social wealth; a medical system based on the concept of“big health”which provides more effective health cares; and the cultural system based on a“bottom-up”concept which makes them better enjoy their life.

摘要： 农村留守老人的供养制度主要包括以种植或养殖为基础的自我供养、以晚辈支撑为 基础的后代供养和以福利支持为基础的社会供养。对中国留守老人而言，“居家养老”仍会是未来一 段时间符合乡村现实的养老方式。目前，“居家养老”所依靠的自我供养和后代供养逐渐呈现衰微的 趋势，社会供养也十分有限。文章通过对留守老人社会角色的重新认知，可以发现他们并非“废弃的 生命”，而是乡村重要的根基。立基于留守老人生命价值的供养制度应当包含: 基于“分享”理念的福 利制度，使留守老人从社会财富中分得应有份额; 基于“大健康”理念的医疗制度，对留守老人的健康 进行防微杜渐式关照; 以“自下而上”理念为基础的文化制度，使留守老人真正获得精神喜乐。
