中文摘要
本文考察环境意识对土地交易的影响。我们利用2015年初中国环境纪录片《穹顶之下》意外发布所造成的外生冲击，并以该纪录片制作人此前标志性节目中受访者的出生地作为接触程度的工具变量。我们发现，对该纪录片接触程度更高的城市，其土地交易活动显著减少。机制分析表明，纪录片发布后，居民对空气污染的意识大幅提高，同时迁移意愿明显上升。这表明环境感知对家庭行为和土地交易具有真实影响。
Abstract
This paper investigates the impact of environmental awareness on land transactions. We leverage the exogenous shock caused by the unexpected release of the environmental documentary Under the Dome in early 2015 in China, and use the birthplace of the interviewees in filmmaker's previous signature program as the instrument for exposure. We observe that the cities with more exposure to the documentary exhibit significant reduction in land transaction activities. Mechanism analysis indicates that after the release of documentary, residents awareness of air pollution increases substantially, accompanied by a notable rise in migration intention. This indicates the real impacts of environmental perception on household behavior and land transactions.
