摘　　要：论文运用实证方法来探讨媒体报道影响民众风险感知的路径和机制,研究以媒体框架和受众框架的差异形成的"框架沟"直接或经由情绪中介影响民众风险感知为假设,以雾霾(有害物质)、转基因(新科技风险)和地震(自然灾害)为代表,建立框架沟、情绪以及风险感知的SEM模型来进行验证。研究发现:第一,相比自然风险,媒体更容易"放大"人化风险;第二,媒体"放大"人化风险的作用机制因风险而异:雾霾报道最为强烈影响民众风险感知,而转基因报道仅仅通过情绪中介来有限地影响民众风险感知。研究证明新闻框架和受众框架的"框架沟"是影响民众情绪和风险感知的关键因素。The study empirically explores the mechanism of media coverage affecting people's risk perception.The research hypothesis that the gap between the media frame and audience is supposed to affect risk perception mediated by emotion aroused by the media coverage.Three SEM models are established to test the relationship among the variables:media coverage,emotion and risk perception and finds:(1)The media magnified human risk,while the natural risk not;(2)the path and mechanism of media affecting risk perception depends on the types of human risk,to which the different news frames of Haze risk and Genetically Modified controversy contributes.
