With the development of our national economy and the advancing of urbanization, a lot of rural land is expropriated, so the number of landless peasants is increasing. They face all kinds of life challenges, in which the old-age security problem is particular, needing the government to assume corresponding responsibility for them in their old age. While in the policy aspect, our government is missing in making old-age security system or the current system is unreasonable. In the super-vision, pension resettlement way is too simplex, local government abuses the compensation of land expropriation, and performance evaluation mechanism is unreasonable. In the financial security, government invests little money and has regulatory problems. So the government should persist the principle of... adapting to the level of economic development and sharing responsibility, speed up the building of the landless peasants old-age security system, perfect the management and supervision, and ensure the security work of capital investment, operation and management. According to the actual situation, government should introduce commercial insurance to assist. Only in this way, the pension rights and interests of landless peasant can really be carried out.
