At macro level, this paper reviews the Old-Age-Allowance policies adopted by the 31 provincial regions in mainland China, and describes the current implementation status. At micro level, using the data of China Health and Retirement Longitudinal Study (CHARLS), and the data of China Civil Affairs Statistical Yearbook (2014) and China Statistical Yearbook for Regional Economy (2014), this paper analyzes the factors that influence the allowance obtaining both on personal level and city level. The results show that the coverage ratio is still low, which indicates that the target of the policy needs clarification. At personal level, age is the most important factor. At the city level, the influence of the economic status relies on the welfare policies to influence the Old-Age-Allowance.
