Every one-unit increase in environmental satisfaction reduces the older adults\u2019 depression scores by 0.426 points. Mechanism analysis indicates that improvements to the living environment enhance the mental health of older adults through three parallel pathways: improving sleep quality (physiological pathway), promoting social participation (behavioral pathway), and strengthening confidence in the future (cognitive pathway). However, the psychological benefits of improvements in the living environment are constrained by three factors\u2014urban\u2013rural disparities, economic income, and personal health, these benefits are more pronounced among three specific groups of older adults: those in rural areas, those with high-income, and those who self-reported good health.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Consequently,future environmental policies should prioritize the synergistic benefits of mental health, and incorporate them into performance evaluation frameworks. This will better facilitate the channeling of policy resources toward groups with limited access to such benefits, further foster an age-friendly social environment, and ultimately promote the deep integration of improvements to the living environment with active aging.<\/jats:p>\n
