The community is a fundamental unit of an individual's life, and the community environment is a significant social component that influences an individual's mental health. In contrast to previous studies that examined the effects of socioeconomic status on health from an individualistic perspective, this research investigated the influence mechanisms and urban-rural variability between socioeconomic position and individual mental health at the levels of perception of environmental pollution and community social interaction. The study found that socioeconomic status was the most critical factor driving disparities in mental health. Environmental and community social interaction mechanisms are essential for closing the class gap. The mediating effect was highly heterogeneous between urban and rural areas, as evidenced by the perception of environmental pollution, which significantly affects rural communities. In contrast, social interactions are mainly visible in urban communities. Consequently, improving ecological governance and community social interactions is critical for reducing health disparities.
