By conversion of the length of period,the urban and rural residents' pension insurance in Tianjin can transfer between the urban and rural basic pension insurance.It takes the lead to break the basic pension insurance segregation between urban and rural areas,and it is conducive to safeguarding the interests of rural-urban migrants.But the policy may lead to moral hazard and unfair.Combination of benefits between the urban and rural basic pension insurance should not only reduce or avoid non-portability loss,but also prevent possible speculative arbitrage,and balance the interests of all stakeholders.At present,the policy barriers result in non-portability loss of rural-urban migrants.The option for policy optimization is to reform the regulation of the length of period for which one has paid the premiums,integrate the premium payment years,calculate insurance benefits respectively and then accumulate benefits of the basic pension insurance in urban and rural areas.However,the ultimate reform goal of basic pension insurance is to establish city-country integrate system of pension insurance system in China.
