Abstract: Under the background of healthy Chinese construction，the deep integration of medical care and old-age care and the gradual establishment of long-term care insurance system will become an important part of healthy aging action.We believe that the social long-term care insurance system represented by Germany， Japan and Korea may be more feasible for us， considering China′s social，economic and cultural forms.The paper comparatively analyzed the funding mechanism and security level in these three countries. Then discussed the effect of economic development on the choice of long-term care insurance model.Combined with the practice and exploration experience in some regions of China， the construction of a long-term care insurance system is expected in the future.
