This study takes the community integration of new urban residents as the object,and describes respective characteristics of new urban residents in Beijing into city life through three cases. The study found that,the level and extent of new urban residents' intergration into different communities can be divided into three categories,namely,new-residents-led positive integration type,state-led passive integration type and integration type of old and new residents' cooperation. Then,with the theory of community and empirical research,the writer generalizes three categories of indicators reflecting the characteristic of community integration—the stablity of city life,interpersonal and community action. The process of community integration can be measured as four stages based on these indicators mentioned above: entering stage-touching stage-accepting stage-integrating stage. This study enhances explanatory power of theory on the phenomenon of new residents' community integration in city. <<
