Abstract: In the theoretical research and practical operation,the problem of supply and demand adaptation of old-age care has received much attention.However,current research is more concerned with “whether it is adapted” and “how to adapt”,but there is little discussion about the definition of adaptation.After the theoretical interpretation of the supply and demand of social services,the theoretical analysis framework for the adaptation of the supply and demand of home-care is initially constructed.Its adaptation framework generally presents a three-dimensional structure,including three consistency states for internal demand,internal supply,and between supply and demand.The adaptation target can have two expectations of “supply constraining demand” and “demand determining supply”.The former is the balance of supply and demand under a certain supply level,and the latter is the balance of supply and demand under the guidance of demand.Its operational indicators also show a two-dimensional differentiation between the controllable and the uncontrollable.In supply and demand practice,more attention should be paid to uncontrollable quantitative indicators.Based on the applicability test of the Shanghai case,the multidimensional theoretical framework can provide a more complete reference system for interpreting and measuring supply and demand adaptation of home-care.
