Based on the theories of the elderly’s life quality and index system，this report put forward a comprehensive index system of the elderly life quality in China（version 1.0）and evaluate the elderly’s life quality in the national wide for the first time. This study uses the Analytic Hierarchy Process（AHP）to determine the weight of the above indicators，and then makes a provincial evaluation on the life quality of the elderly in China using the data of The Fourth Survey on The Living Conditions of the Elderly in China conducted in 2015. The conclusion of this report is that contemporary China has entered a new era with the highest quality of life for the elderly in the history of China. the objective standard of living is still the most important factor affecting the life quality of the elderly，the elderly’s life quality in the eastern region is better than other areas，and all provinces have their own weaknesses. To solve these problems is not only an important direction of scientific research on ageing in the new era，but also an important focus of actively dealing with the population ageing issued by the central government.
