Population hollowingout has become the main constraint of the multiservice for the rural oldage care in China, which has impact on all aspects of rural residents’ life style, work conditions, community culture and economy. The gap between urban and rural areas has weakened the family function for intergenerational support, even when the family functions adapt to it through the “grandparenting” and “daughter endowment”. The government has strengthened the role of the bottom line, but his open role of institutional innovators may be prone to fall into the “leading illusion” and “innovation blind spots”. The primary governance organizations are influenced by the population loss, which leads to the gap between their management ability and what the villagers need for in the oldage care. The problem of “atypical dysfunction” in the voluntary sector has negative impact on its development. The government supplies its development, but the institutional environment and community network constrain its work. So to break through dilemma of multiservice provisioning, the government should switch its “leading” role to “platform” role and construct the social cooperation network through knowledge transfer mechanism, cooperative correction mechanism and nonmonetary reward and punishment mechanism.
