摘要： 针对特大城市特点及其养老趋势，提出一种灵活多样、良性开放的可持续养老模式：集体自助养老（CSE），对其定义、目标、类型、影响因素进行分析。结合六西格玛服务设计、产品服务系统设计、可持续养老理论，围绕养老目标，建立可持续养老CSE服务系统设计理论体系。可持续养老服务系统设计存在若干可行解，围绕提升养老满意度，提出CSE服务系统设计框架，充分利用信息化社会优势，对CSE产品与服务进行集成设计，建立CSE服务系统配置模型，分析了CSE服务系统选择、构建影响因素，根据不同的养老需求和有限的养老资源、成本设计不同的集体自助养老方案，满足特大城市多元化、个性化的养老需求，为可持续养老服务系统设计提供有益思路，为特大城市养老资源配置、养老基础设施建设提供参考。
