公众环境风险感知对行为选择的影响路径

心理测量范式、风险社会放大框架、社会表征理论等已成为社会风险感知研究的主流理论，但风险感知对行为选择的影响路径成为不解“谜团”。基于以上理论，通过对“2017年城市化与新移民调查”数据分析，构建了环境风险感知到行为选择的多维度路径模型，研究发现：风险感知分别对新媒体使用、社区环境效能感、社会参与和政治参与有着不同程度影响，同时这四个变量也影响了公众的环境行为选择。环境风险感知对行为选择的影响路径中，新媒体使用、环境效能感和政治参与分别起到了“放大”或“缩小”不同的中介效应。因此,政府通过与新媒体有效融合，增进公众的政治参与，提升公众对环境的满意度，进而引导公众的理性判断和环境负责任行为。

The Influence Path of Public Environmental Risk Perception on Behavior Choice

Theories on risk society amplification framework,social representation have become the mainstream in the study of social risk perception.However,the influence path of risk perception on behavior choice is still a mystery.This study,based on the above theory and through the data analysis of "2017 Urbanization and New Immigrants Survey",builds a multidimensional model of the path of environmental risk perception on the behavior choice,finding that risk perception has different effects on the use of new media,community environmentalefficacy,social participation and political participation.At the same time,these four variables also affect the public choice of environmental behavior.In the path of the influence of environmental risk perception on behavior choice,the use of new media,the sense of environmental efficacy and political participation have played different mediating effects,enlarging or narrowing the effects respectively.Therefore,through effective integration with new media,the government can enhance the public's political participation,and improve their satisfaction with the environment which can guide the public to judge rationally and act responsibly in the evironment.
