This paper aims to examine the effects of social networks on trust from a comparative
perspective based on survey data collected in Daegu and Gwangju. For the purpose, the social
networks are classified into two types of strong and weak networks according to the strength of
tie; and trust is divided into two categories of trust in people and trust in institutions, to classify
again the former into four types of particularized trust, generalized trust, trust in Korean people
and trust in local residents, and the latter into two types of trust in central government and trust
in local government. The effects of the two types of social networks on the six types of trust
were analyzed by the statistical method of multiple regression analysis.
Results of analysis are as follows. In the category of trust in people, strong networks in Daegu
and Gwangju in common have positive effects on particularized trust, trust in Korean people and
trust in local residents, which all are ‘identity-based trust.’ And weak networks in the two regions
in common have a positive impact on generalized trust in generalized others. In the category of
trust in institutions, strong networks in the two regions in common have positive effects on trust
in central government and trust in local government, but the effects of weak networks vary in
the two regions according to the governments.
