The elderly choosing the ways of old-age care according to their resources endowment is the rational choice. This paper classifies the resource endowments that affect the choice of the old age pension potentially into biographical characteristics endowment, economic endowment and self-care ability endowment, and analyses the influence of these endowments on the way of old-age care by using the data from ‘2012 China Longitudinal Aging Social Survey’ （CLASS 2012）. The research finds that old women, the old people with smaller age and the old people with high income tend to choose to age in nursing home, and that self-care ability endowment does not have a significant effect on patterns of old-age support. Thus, the demand of the elderly on nursing homes shows the rising trend, on the one hand, the government should satisfy at supply-side the demand of multiple old-age care methods, raise service quality of old-age-care at home, increase the number of old-age-care agencies, and set up new-type old-age-care mode with three dimensions, on the other hand, governments should pay attention to the resources endowment situation of the elderly, especially ensure the income level of the elderly.
