Based on the survey data of 2,801 older adults living alone in Chengdu, Shanghai, Guangzhou, Hohhot, and Dalian, the quantitative index of their “ac-tiveness in SPS” was constructed. The OLS model, the Ologit model, the instrumental variable method and the mediating effect were used to explore the influence mechanism of perceived family relation-ships of urban older adults living alone (UOALA) on their SPS. The results demonstrate that: (1) UOALA's activeness in SPS in China is generally at a low level; (2) perceived family relationships have an impact on UOALA's activeness in SPS, i.e. positive family relationships will increase their activeness in SPS, and there are evident gender differences in this tendency; (3) there are regional differences in the activeness in SPS among the older adults living alone in urban areas, and perceived family rela-tionships in first-tier and second-tier cities have a more significant impact on their activeness in SPS; (4) the mediating effect analysis shows that perceived family relationships can indirectly promote urban old people’s activeness in SPS through the reconstruction of their self-respect, and this is more pro-nounced in women. Therefore, the important role of families cannot be ignored in promoting SPS of the older adults.
