Based on the data from the survey of “Economic Value of Informal Care”，organized by the China Population and Development Ｒesearch Center and the Ｒesearch Center of Healthy Aging and Social Security of Nankai University，in four provinces and cities in China in 2019, we use Contingent Valuation Method ( CVM) to evaluate the economic value of informal care and to test the impact of income level and health status on the economic value. The study found that for informal care，the average amount of respondents’willingness to pay (WTP) is 31.73 yuan per hour, and the average amount of willingness to accept ( WTA) is 41. 98 yuan per hour．Income levels and health status only have a significant impact on the amount of WTP，and don’t affect the WTA．In addition，comparing with the control group，respondents who are older, suffer from chronic diseases，have no spouse，have a junior high school education, and do not live in their own houses are more likely to be unwilling to pay for or accept subsidies for the informal care．The conclusions of this paper will provide a decision-making reference for the government to issue the support policy of informal care．
