Abstract

In order to empirically verify the integrative hypothesis of the Social Integration Model-Group Threat Theory, this paper examines the relationship between the proportion of foreigners in residential areas and Koreans' perception of group threat and collective efficiency. This analysis is conducted at the exploratory level using regression tree analysis. The case of 800 Korean residents was utilized as secondary data in the “Research on Measures for Strengthening the Efficacy of Criminal Policy for Guaranteeing Public Safety (IV): A Study on the Safety Condition and Policy Issues in Foreign Population Concentrated Areas” conducted by the Korean Institute of Criminology and Justice. As a result of the main analysis, it was found that the integrated hypothesis of the Social Integration Model-Group Threat Theory, which has been discussed in Western society, was partially supported. However, the factor of perceived group threat had a significant effect only in multi-ethnic communities with more than 50% of foreigners in predicting collective efficiency. Through the derived results, the study suggests the necessity of implementing a control policy to mitigate the spread of anti-multicultural emotions resulting from the increasing ethnic diversity. Finally, the study also presents its limitations.
