中文摘要：

共享发展成果，为全体人民谋福利，是社会主义的本质要求。然而现行社会福利机制面临三元福利桎梏：农村社会福利发展迟滞，传统多重保障功能弱化；城市福利机制社会化改革缓慢，各方有效资源整合力度缺乏；农民工特有“半城市化”属性导致其社会福利处境尴尬。因此，依托共享理念，以城乡协调、均衡发展、因地制宜、区域统筹、强化合力等为原则，指导当前福利机制建构尤为必要。国家主导、市场配置、社区依托以及组织参与多路径协同推动福利机制实践，深化福利机制改革，将是社会建设的重中之重。

英文摘要：

Sharing development achievements, seeking welfare for the people are the essential requirements of socialism. Social welfare mechanism faces three problems ： the development of rural social welfare mechanism is slow, the function of traditional multi guarantee weakens ; social reform of urban welfare mechanism develops slowly, there is lack of effective resource integration; ＂semi-urbanization＂ of migrant workers forces them into awkward situation. Therefore, based on shared concept, with the principle of urban and rural coor- dination, balanced development, adjusted measures to local conditions, balanced development in region, strengthened combined forces, it is important to instruct the construction of welfare mechanism. State dominant, market disposition, community support and organization involvement, promoting welfare mechanism practice, deepening welfare reform are top priorities of social construction.
