摘要

There is tentative evidence suggesting that socioeconomically disadvantaged groups may benefit more from access to neighbourhood greenspace and therefore could be a lever for narrowing socioeconomic inequalities (‘equigenesis’) in mental health, although studies are equivocal. One potential explanation for this inconsistency is differences in study designs, particularly how greenspace is measured. Most previous studies are from high income countries, and there has been no investigations into equigenic environments in China. Using survey data collected from 26 neighbourhoods in Guangzhou, China, this study examines whether local greenspaces may narrow socioeconomic inequalities in health (i.e. equigenesis) in the Chinese context. The study is the first to explore the contribution of greenspace in reducing socioeconomic inequalities in mental health in the Chinese context. It uses Normalized Difference Vegetation Index (NDVI), Street View Greenness (SVG) and self-reported neighbourhood greenness quality as estimates of residential greenness exposure Results show that SVG-quantity, SVG-quality and self-reported greenspace quality narrow the neighbourhood socioeconomic inequalities in mental health. Our findings demonstrate the importance of improving equity in local green infrastructure for promoting health equity through urban planning and design, including improving access to green spaces, and providing more street trees in socioeconomically disadvantaged neighbourhoods.
