摘要
空气污染能否得到有效控制与缓解,很大程度上取决于民众的行为响应程度。本研究透过结构方程式模型(Structural equation modeling,SEM),检验民众日常媒介使用频率、风险经验、风险感知、风险下资讯获取与行为响应之间的具体关联度,进而讨论如何有效地向民众传播空污风险资讯。研究发现,民众在日常生活中较常使用网络媒体与人际传播获取空污资讯,且这两种媒体能够显著影响到民众的空污风险感知与风险下的资讯获取渠道,而风险经验对民众风险感知与风险下的资讯获取之影响不显著;另一方面,在风险感知中,严重性与关心程度更容易促使积极的行为响应,而易感性与自我效能感对行为响应的影响不显著;最后,本研究也为政府和媒体如何有效提升民众的空污风险感知与行为响应水平提出了具有针对性的策略建议。
Whether air pollution can be effectively controlled and mitigated heavily depends on the degree of behavioral response of the public.Through Structural equation modeling(SEM),this study examines the relevancy between the behavioral response of the public and their frequency of daily media use,risk experience,risk perception,and information acquisition under risk,to further discuss how to effectively communicate information about risks of air pollution to the public.The study shows that people often acquire information about air pollution through network media and interpersonal communications in their daily life,and these two media can significantly affect the public’s risk perception of air pollution and access to information acquisition under risk,while risk experience has no noticeable effect on information acquisition under risk.In terms of risk perception,perceived seriousness and concern level are more likely to trigger positive behavioral responses,yet the influences of susceptibility and self-efficacy are insignificant.Finally,this study also provides targeted strategic suggestions that are put forward herein on how the government and media can improve the public’s risk perception of air pollution and the level of behavioral response.
