Over the past year，the coverage of basic old-age insurance in China was further expanded，the scale and amount of the insurance fund also increased. Reform of basic old-age insurance has seen progressive results：pension system unification made substantial progress，regulation of old-age fund investment management was launched，Interim Measures for Occupational Annuity Fund Management was soliciting public opinions，basic pension of retired people increased again，premium rate of old-age insurance went down. Currently，problems concerning basic old-age insurance system in China include：policy on individual pension account needs to be improved，channels for fund investment management need to be expanded，and old-age insurance processing management needs to be specified. For reform at the next stage，research should focus on top-down design of old-age insurance and improvement of individual accounts，so as to achieve the fairness and sustainable development of old-age insurance system in China.
