Using data, we analyze the "sideline effect" and inherent contradiction of transformational cities, research the policy needs for social security and its trend in the citizenization process of the peri-urban farmers. On this basis, we construct the social security policy system that can adapt to the accelerated process of urbanization. Finally, we put forth the following recommendations for the social security policy in the citizenization process of the peri-urban farmers: distinguishing different groups' policy needs for social security; attaching importance to people's dynamic policy needs for social security in urbanization; focusing on the adaptability of social security policy transformation in urbanization; attaching importance to the social psychosocial environment of social security policy transformation in urbanization; achieving the trinity of non-farm conversion, urbanization and citizenization in the process of urbanization; strengthening the government's dominant position in the building of social security policy system.展开更多

Result shows that the system layer includes the unreasonable land compensation, the lack of social security for land-losing farmers, and the employment exclusion of land-losing farmers. Small scale and low heterogeneity are the causations for social support network. Low willingness to become citizens, low cultural quality and difficulty in role change are the causations of land-losing farmers themselves. The low expected return and high living cost are the causations for economic layer. Based on the above analysis, countermeasures to improve the urban-living ability of land-losing farmers are put forward, such as improving the land expropriation system, establishing a multi-level social security system, enhancing the training and employment mechanism of land-losing farmers, and improving the quality of land-losing farmers.展开更多
