目的：为了解家长对室外空气污染的迁移倾向和支付意愿，并探讨相关影响因素，采用方便抽样方法，分别从武汉市武昌区某社区和武汉市儿童医院抽取调查对象。本研究采用问卷调查法。采用单因素和多因素Logistic回归模型分析父母个体和家庭特征与改善空气质量相关行为意向的关系。结果：共调查问卷865份，回收率为86.5%。有流动意愿者中，医院组150人（36.4%），社区组139人（30.7%）。在医院组中，空气质量知识水平高（OR = 6.268，p < 0.05）、家庭年平均收入≥ 5万元（OR = 2.045，p < 0.01）的人群更倾向于迁移。AAHI（OR = 1.939，p < 0.05）也是社区人群中相应的影响因素。愿意为空气质量改善付费的人包括297人（72.1%）来自医院组，333人（73.5%）来自社区人群，影响因素是公众对空气质量改善的责任感结论：武汉市居民为躲避恶劣的空气环境而迁移的倾向性较高，愿意为改善空气质量而付费。地方政府应该更加关注家长对空气污染的认知，以及对政府管理空气质量的态度，尤其是那些愿意迁移的家长。
Objective: To understand parents' propensity to migrate and willingness to pay with respect to outdoor air pollution, and to explore related affecting factors.Methods: This study used a convenience sample and subjects were collected from a community in Wuchang District and Children's Hospital of Wuhan, respectively. A designed questionnaire was used for this study. Univariable and multivariable logistic regression models were applied to analyze the relationship between parents' individual and familial characteristics and related behavioral intensions to air quality improvement. Statistical analysis was done with SAS 9.1.Results: The questionnaire was completed by 865 subjects (response rate = 86.5%). The number of people with migrant intent was 150(36.4%) from hospital group, and 139(30.7%) from community group. In the hospital group, subjects with higher knowledge of air quality (OR = 6.268, p < 0.05) and higher average annual household income (AAHI), which was equal or more than 50,000 Yuan (OR = 2.045, p < 0.01), were found to be more intent to migrate. AAHI (OR = 1.939, p < 0.05) was also the affecting factor in the community group correspondingly. Those willing to pay for air quality improvement included 297 people (72.1%) from the hospital group and 333 people (73.5%) from the community group, and affecting factors was the public responsibility for air quality improvement (hospital group: OR = 3.380, p < 0.01; community group: OR = 4.436, p < 0.01).Conclusions: This study indicated high tendency of propensity to migrate for avoiding poor air condition and willingness to pay to improve air quality in Wuhan. Local governments should pay more attention to parents' knowledge of air pollution and attitudes towards government management of air quality, especially those willing to migrate.
