Abstract: This paper investigates and compares the effects of improving the contribution rate and postponing the retirement age on capital stock per worker, personal and social pooling account pension level and other economic viarables within the framework of General equilibrium OLG model. Our results show that, firstly, improving the contribution rate of personal accounts has no effect on capital stock per worker and other variables except that it can improve personal account pension and reduce private savings. Secondly, capital stock per worker, wage, private savings, consumption of the first period and utility will be reduced by postponing retirement age and improving contribution rate of the social pooling account. Thirdly, return to capital, personal accounts pension and social pooling account pension can be improved by postponing retirement age and improving contribution rate of the social pooling account. Fourthly, consumption of the second period can be improved by postponing retirement age, but adverse when increasing contribution rate of the social pooling account. These results suggest that postponing retirement age is superior to improving contribution rate of the social pooling account.
