Abstract: One major cause of the low degree of our country's social old-age insurance for peasant workers lies in the lack of integrated institutional arrangement in terms of social old-age insurance for peasant workers on state level.The low degree of our country's social old-age insurance for peasant workers also results in the disunity and poor performance of our regional policies.So,the construction of our country's social old-age insurance for peasant workers should stick to the principle of flexibility,with efficiency and fairness being taken into consideration as well.Therefore,a transferable,accumulative,and fully flexible new type of social old-age insurance for peasant workers should be realized,so as to create an appropriate institutional platform of the integration of China's urban and rural social old-age insurance.

Key words: social old-age insurance for peasant workers, institutional arrangement, institutional innovation, flexible design
