As population mobility constantly increases

migrant groups are not only concerned with their own development

but also the harmony and stability of the entire community. Empirical studies show that: 1) the social factors of knowledge-based migrants' health have high similarity to those of residents. Social economic status and interpersonal trust exerts significant influence on self-reported health of knowledge-based migrants. 2) compared with knowledge-based migrants

migrant workers are more affected by subjective factors like government trust regarding to self-reported health. Government trust have positive influence on the self-reported health of migrant workers. Therefore

attention to subjective social factors of migrant groups is of positive significance for reducing health risks of knowledge-based immigrants and migrant workers

eliminating health differences

and consolidating social stability and fairness.
