Abstract: Establish a multipillar social security system is an important content of the 19th Party Congress Report. Promoting the different pension pillars coordinated development is the most significant task in deepening social security reform. This paper finds that there is a large space for the development of supplementary pension insurance through the calculation of the actual rate and replacement rate of basic oldage insurance. This paper tries to establish a transition channel between different pension insurance systems under a multi pillar structure by decomposing the present value and its rights of individual account funds. The research shows that it is essential that setting a vertical way to transfer for individual account funds and it might weaken the crowding out effect among the multi pillars system. As a result, it is beneficial not only to expand the coverage of supplemental pillars, but also to keep the coverage of the basic pension system steady.
