To improve household air quality, the Chinese government has launched a number of pilot stove renovation projects, but few studies have explored the impact of the project on people's perception of and willingness to participate in these renovations; moreover, factors affecting willingness to pay for the project in rural China are not yet clear. We conducted a field measurement and a corresponding door-to-door questionnaire survey using the renovated group and the unrenovated group. The results showed that (1) the stove renovation project could not only reduce PM exposure and the excess mortality risk of rural residents, but also (2) improve residents' risk perception and self-protective willingness. (3) Specifically, the project had a deeper impact on female and low-income residents. (4) Meanwhile, the higher the income and the larger family size, the higher the risk perception and self-protective willingness. (5) Furthermore, willingness to pay for the project was related with residents' support for the project, benefit from renovation, income, and family size. Our results recommended that stove renovation policies should pay more attention to families with lower income and smaller size.
为改善家庭空气质量，中国政府已启动了多个炉灶改造试点项目，但很少有研究探讨该项目对人们对这些改造的认知及参与意愿的影响；此外，影响中国农村地区该项目支付意愿的因素尚不清楚。我们对改造组和未改造组进行了实地测量及相应的挨家挨户问卷调查。结果表明：（1）炉灶改造项目不仅可以降低农村居民的颗粒物暴露及超额死亡风险，而且（2）能提高居民的风险认知和自我保护意愿。（3）具体而言，该项目对女性和低收入居民的影响更大。（4）同时，收入越高、家庭规模越大，风险认知和自我保护意愿越高。（5）此外，该项目的支付意愿与居民对项目的支持、改造受益、收入及家庭规模有关。我们的结果建议，炉灶改造政策应更多关注低收入和小规模家庭。
