Abstract: The rural old-age insurance system should be constructed from rural economic development diversity and designed from different economic development levels. The family support should be constructed mainly as old-age insurance mode in poor country, the combination of family support and community support should be constructed in subsistence country and the unified social old-age insurance of city and country mode should be constructed in wealthy country. The old-age insurance of peasant-workers in cities and peasant people losing territory should be considered at the same time.
