China is rapidly moving into an aging society. The fast aging population and lack of necessary elderly care resources and organizational capacity make it necessary for policymakers to amass information about current elderly care resources, either in the public or private sector, and elderly care service demands, and make informed and intelligent policies to enable collaborative efforts from different social entities to deal with this new challenge. This paper studies elderly care data resources management practices in Northeast China and analyzes how the studied capital cities build platforms, select, gather, manage, and utilize elderly care data for elderly care policy making and service provision. These data come from different sources, have other formats, are normalized differently, and are owned by various social entities. To enable their standardization, compatibility, and efficient use, skills, collaborative methods, principles, and institutions are needed to constitute the conceptual framework for collaborative governance. The study shall extract lessons and experiences from the studied cases in the context of this theoretical guidance and develop policy recommendations for future digital-enabled elderly care practice.
