For students, studying abroad has its advantages but might also have unwanted adverse effects, such as social isolation and loneliness. We comparatively analyse the role of emotional support in understanding loneliness among Chinese international students and local students in Germany from a gender perspective. Based on a unique sample, our findings suggest that Chinese international students experience higher levels of loneliness than local students. Female Chinese international students are less lonely compared to male ones, whereas the opposite is true for local students. Surprisingly, having a higher number of emotionally supportive ties is associated with higher levels of loneliness for all students. Our subgroup analysis further revealed that the relationship between emotional support and loneliness varies by gender and student status. Female local students benefit from having more emotionally supportive ties, while the opposite is true for female Chinese international students. We recommend conducting a longitudinal study for examining the causality of the relationship between networks and loneliness in the future. Our findings have implications for universities and higher education research in addressing loneliness among students.
