中文摘要：

在中国核电站项目重启的背景下，更好地理解公众对于核电项目的风险感知有助于项目的风险沟通．保证项目实施的社会环境。以风险感知理论为基础，分析了信任、情绪和信息获取因素对于核电项目的公众风险感知的作用。构建结构方程模型并利用层级回归的方法，重点验证分析各变量之间的作用机理。研究结果表明，公众对于媒体、政府、专家、企业的信任并不直接作用于公众的风险感知；负面情绪正向影响公众风险感知水平，而信任反向调节负面情绪与风险感知的关系；信息获取对于信任有显著正向作用，而对于负面情绪的作用不明显。

英文摘要：

To restart nuclear power plant projects in China, a better understanding of public risk perception is conductive to risk com- munication and stability of social environment of the projects. This article analyzed the factors including trust, emotions and information acquisition affecting the public risk perception of nuclear power plant projects based on the risk perception theory, and used structural equation model and hierarchical regression to demonstrate the function mechanism of the variables and relevant theoretical hypothe- sis. The results showed that the trust of media government expert and enterprise didn＇t have direct effects on risk perception; the nega- tive emotions had positive effects on risk perception and the trust negatively regulated the relationship between negative emotions and public risk perception ; the information acquisition had positive effects on the trust, but it was not obvious as for the effect on the nega- tive emotions.
