Based on the comparative analysis in varied resettlement programs, the paper believes that it is the most practical alternative to establish a Social Security System for the Out-of-land Peasants(hereinafter called SSSOP). The SSSOP should provide them with the following components at least: social endowment insurance, medical social insurance, unemployment social insurance, minimum standard of living and job training and law aids. The key point of the SSSOP building is to enhance its implementation feasibility, leaving other aspects to be improved in the future. According to the present situation in China, the "land for social security" alternative is the only way to ensure smooth implementation of the SSSOP. After applying relevant theories of the property right economics and system economics to the analyze of the defects of the existing land property relations and land acquisition system, the article points out the existing land system defect (mainly the property relations system and the land acquisition system ) has already become the original factor that restraints the SSSOP implementation. In favor of implementation of the social security system for the out-of-land peasants, the article argues that innovation of the land property relations should take the "Gradual Reform" road, which includes a combination of the social security and cash compensation available for the out-of-land peasants, a special account and social security fund established for the out-of-land peasants, as well as a out-of-land peasants' participation system in the land acquisition. |
