新媒体影响力对雾霾风险感知的作用机制

基于“2017年中国城市化与新移民调查”随机调查数据,通过已有文献构建新媒体影响力和雾霾风险感知指标,采用中介效应模型验证并探索新媒体影响力对雾霾风险感知的影响及其作用机制。研究发现:提高新媒体影响力,能有效降低雾霾风险感知,而政府环保评价起着显著的中介效应的作用;并且新媒体影响力可划分为官方媒体影响力和非官方媒体影响力;官方媒体影响力不仅直接影响雾霾风险感知,而且通过政府环保评价间接对其产生影响;而非官方媒体影响力仅通过政府环保评价对雾霾风险感知产生间接影响。因此,媒体融合时代下,提升公众对官方媒体使用频率,拓宽官方媒体信息发布喋道,完善公开透明的信任机制,同时加强对非官方媒体的信息监督和信息反馈机制,完善政府风险沟通机制,对现阶段中国环境风险的源头治理具有现实意义。

The Effect Mechanism of New Media Influence on Haze Risk Perception

Based on the data of "China Urbanization and New Migration Survey in 2017", the new media adopted an intermediary effect model to study the impact of new media influence on haze risk perception and its mechanism of action by constructing new media influence and haze risk perception indicators. It is found that increasing the new media influence can effectively control the risk perception of haze, and government environmental protection evaluation plays a significant intermediary effect. New media influence is further divided into the official media influence and unofficial media, found that the official media have influence to the haze risk perception is not only a direct impact, and plays an indirect effect through the government environmental evaluation, and unofficial media mainly through government environmental influence evaluation has the indirect impact on the haze risk perception. As a result, in the era of media convergence, the research conclusion is of great significance to improve the public official media use frequency, widen the channel of the official media information release, to improve the trust mechanism, to strengthen information supervision of unofficial media and information feedback mechanism, and to perfect the government risk communication and information release mechanism,, which will realize the source governance of risks in China.
