Abstract: Using the 2018 China Longitudinal Ageing Social Survey (CLASS2018), this study constructs a composite index representing “productive ageing” based on nine activities, including helping children do housework, caring for grandchildren, and working. By employing simultaneous equations model, the health performance of “productive ageing” in China is identified. The results show that participation in “productive ageing” activities significantly improves the physical and mental health of older adults. These impacts differ significantly across gender, age, and education levels. When the participation level of “productive ageing” activities is low to moderate, its improvement effect on the physical health of older adults is better. However, when the frequency of helping children do housework and working is moderate, it negatively affects the mental health of older people. The effect of the number of “productive ageing” activities on older adults' physical and mental health exhibits an inverted Ushaped distribution. Notably, two or three “productive ageing” activities yield the best physical and mental health performance for older people.
