制度经济学认为制度设计受价值影响,也应将其蚋入研究范畴。社会保障作为一种主要的公共制度,背后的价值理念也应该蚋入政策设计的范畴。失地农民是一个超越城乡二元分割的新生群体,兼具城乡居民的经济特征,其社会保障的实施过程反映了我国社会保障政策设计的价值转向,主要体现为由“效率为主、兼顾公平”要以追求社会公平为目标,由主要时生存权的重视到对发展权的关注,由物质帮助为主到兼顾人文关怀。 Institutional economics that the system design by the value of influence, should also be included in the research category. Social security as a major public system, the concept of value behind should also be incorporated into the scope of policy design. Land-expropriated peasants are a new-born group that transcends urban-rural duality and combines the economic characteristics of both urban and rural residents. The implementation of social security reflects the value orientation of social security policy design in our country, which is mainly reflected in that “efficiency is the mainstay and fairness is taken into account ”We should pursue social fairness as the goal, pay attention to the right to development from the primary right to subsistence, and be mainly concerned with the humanistic care through material assistance."
