Affective quality is the psychological quality of individual temperament. On the basis of reviewing relevant literature and interviewing youth and experts，current study developed an original investigative tool-“questionnaire on beijing youth’s affective quality”，which includes 6 dimensions and 17 factors. This study investigated the affective quality of 2414 young people born from 1980 to 2002，and compared the affective quality among different groups.

The results show that the affective quality of new youth Residents is at a medium level，and their scores are higher than those of young people from other places，but lower than those of young people from local residents. The score of female youth group is obviously higher than that of male，showing the characteristics of higher education level and higher affective quality score. Among the total affective quality scores，the financial industry，civil servants and computer fields scored the highest，while the unemployed had relatively low affective quality. Compared with migrant workers，returnees and white-collar young workers in the Beijing，the results show that migrant workers have relatively low scores，returnees and white-collar workers have higher scores，and overseas experience cannot significantly improve affective quality scores. Examining the influencing factors of affective quality，it is found that the sense of city pride，sense of integration，self-esteem and adaptability have a significant impact on the affective quality of returnees，white-collar workers and migrant workers in Beijing’s new youth residents.
