中文摘要：
通过在雾霾严重时期收集的大规模问卷调查数据，建立了雾霾感知风险等因素与应对行为之间关系的结构方程模型．分析显示，对环境信息越敏感、雾霾感知风险越大、对雾霾知识了解越多、雾霾感知可控性越大的公众会采取更多的防护与应对措施，他们对相关防护产品的购买意愿也越强．特别是，感知风险在环境信息与应对行为以及环境满意度之间起着重要的中介变量作用，即当雾霾污染引起人们的感知风险时，会促使他们采取更多的应对行为，并且对环境满意度评价产生负面影响．另外，雾霾感知可控性在雾霾知识熟悉度与应对行为以及环境满意度之间起着部分中介变量的作用．
英文摘要：
A structural equation model has been developed to study the perceived risk of smog, related factors and coping behaviors, based on the data collected from a large-scale questionnaire survey during the recent se- rious smog time. Results show that individuals who are more sensitive to environmental information, who have a higher level of perceived risk and more knowledge about smog, and who perceive more controllability, will be more likely to have protective and coping behavior, and more willing to purchase health protection prod- ucts. In particular, perceived risk plays as a strong mediation role between environmental information and cop- ing behaviors as well as environment satisfaction. In other words, when smog pollution arouses public per- ceived risk, they will take more coping behaviors and will give a worse evaluation of the environment. In addi- tion, the perceived controllability of smog plays a partial mediation role between the familiarity of smog knowl- edge and coping behaviors, and between the familiarity of smog knowledge and environment satisfaction.
