Mortality Force Analysis Based on Old and New Life Tables of China

WANG Zhong-jun,ZHANG Lei,TIAN Wu-feng(School of Science,Wuhan University of Technology,Wuhan 430063,China)  
This paper firstly compares the life table(CL1990-1993) and(CL2000-2003),quantitatively analyzes the change of mortality force,and finds that mortality is decreasing.Then this paper simulates the mortality force by parameter graduation,estimates the value of three parameters in Makeham function based on least square method and iterative computation.The hypothesis test shows that the simulation effect is significantly improved.Finally this paper proposes function for the randomization of mortality force with time lapse based on these two tables and optimizes the simulation results.
