Abstract: As the basic unit of human society，the normal functions of families represent an important prerequisite for the development of society．Development capability of family is the ability to meet the living and development needs of each family member，mainly including six capacities of support，economic ability，learning，social interaction and risk response，which can be achieved through two ways of intra － family construction and external social supports．However，with the process of weakening， transformation，externalization and socialization of family functioning，there are emerging new trends about families that corresponding structural imbalance between the needs and function of families and mechanism failure of self － supply and demand balance，as a result family capacity building depends on more external supports now than past．Therefore，we should focus on changing of the family' s core function and the difficulties faced by families，take family as a basic unit of social policy，actively build a family － friendly social environment and institutional support，thus fully promote the development capacity of family．
