Abstract: This study aims at investigating parenthood attitude toward adult children’s second birth under the“two-child”policy based on the Beijing Empty Nest Family Survey in 2015．The survey shows that the elderly present high awareness rate of the“two-child”policy; old parents who support，oppose to，or hold the idea of non-interference to their married children’s second birth account for one third re- spectively; almost 70% of the elderly would support their adult children’s second birth through economic assistance or child care; utilitarian purposes，such as old age care，are no longer primary reasons for second birth; economic cost，concern about mothers’or baby’s health and lack of child care resources become the top three factors preventing second birth．Having a good relationship with adult children， good health condition and being currently married have a significantly positive effect on parenthood support- ive attitudes toward adult children’s second birth; open-minded idea on endowment，education and duration of the empty nest period significantly reduce the probability of the elderly to support children’s second birth; and no significant effect is found with gender，age，economic condition and preferable place for old age life．
