通过实验法,从报道强度(包括报道数量和持久度)和报道框架(包括报道归因和报道导向)两方面考察突发风险事件传播的报道模式对公众风险认知的影响。结果表明,风险事件报道越强烈,公众风险评估水平越低;既包含可控归因信息又包含不可控归因信息,或既包含正面信息又包含负面信息风险事件报道,公众风险评估水平最低;仅包含不可控归因信息,或仅包含负面信息的风险事件报道,公众风险评估水平最高。
Through experiments, this paper examines the impact of reporting patterns of public risk appeals on the coverage intensity of reporting (including the number and duration of coverage) and the reporting framework (including reporting attribution and reporting orientation). The results show that the stronger the coverage of risk events, the lower the level of public risk assessment, the controllable attribution information and the uncontrollable attribution information, or the coverage of risk information of negative information, and the lowest level of public risk assessment. Risk incident reports containing only uncontrollable attribution or negative information only have the highest level of public risk assessment.
