Abstract: The paper studies on the mortality improvement in China since 1949. Comparison is made by age, gender, urban and rural, insured and general population, gap between China and developed countries etc. in order to discuss the difference among them and provide evidence for longevity risk management. The result shows that the mortality of Chinese population has been improved consistently since 1949 and the mortality improvement decreases with age. Large mortality improvements were exhibited across all ages in the last decade, particularly for infants and individuals above 55. For the rates of mortality improvement, females are greater than males, the city is higher than the town and countryside and the insured are stronger than the general at most ages. Moreover, China has experienced larger improvements than other countries for most age groups. This is mainly due to the enhancement of life quality and medical technology for Chinese. It also indicates that there is a large space for Chinese mortality improvements.
