Limited studies examined the interaction effects between exposure to ambient PM and economic development on the settlement intention of floating population. We used binary logistic model to examine the association of PM, per capita GDP (PGDP), PM [Formula: see text] PGDP on the settlement intention. Additive interaction term of PM and PGDP level was used to investigate their interactive effects. Overall, each one grade increment in annual average PM was associated with decreased probability of settlement intention (OR = 0.847, 95%CI: 0.811-0.885). The interaction effect between PM and PGDP on settlement intention was significant (OR = 1.168, 95%CI: 1.142-1.194). The stratified analysis showed PM exhibits lower settlement intention in the aged 55 years or above, engaged in low-skilled works, and living in the western China. This study indicates that PM-exposed will decrease the settlement intention of floating population. High economic development level can weaken the relationship between PM and settlement intention. Policymakers should balance the socio-economic development and environmental health and focus on vulnerable population.
有限的研究考察了暴露于环境 PM 和经济发展对流动人口定居意愿的交互作用。我们使用二元逻辑模型来检验 PM、人均 GDP（PGDP）、PM [公式：见文本] PGDP 对定居意愿的关联。使用 PM 和 PGDP 水平的加性交互项来研究它们的相互作用。总的来说，每年平均 PM 的每增加一个等级与定居意愿的概率降低相关（OR=0.847，95%CI：0.811-0.885）。PM 和 PGDP 对定居意愿的交互作用显著（OR=1.168，95%CI：1.142-1.194）。分层分析表明，PM 在 55 岁或以上、从事低技能工作和居住在中国西部的人群中表现出较低的定居意愿。本研究表明，PM 暴露会降低流动人口的定居意愿。较高的经济发展水平可以削弱 PM 与定居意愿之间的关系。政策制定者应平衡社会经济发展和环境健康，并关注弱势群体。
