利用中国综合社会调查2013年的数据,使用回归分析研究了媒介使用和信息认知能力对于公众环境科学知识获取的影响。结果表明,媒介使用能够同时提升客观环境知识水平和主观环境知识感知,信息认知能力在媒介使用与客观/主观环境知识间起到了正向调节作用。具体的媒介效果分析显示,传统媒介使用对于客观/主观环境知识均具有显著的正向效应,新媒介使用只与客观环境知识存在显著的正相关。传统媒介中,报纸使用与客观/主观环境知识均存在显著的正相关,杂志使用仅与客观环境知识存在显著的正相关,广播与电视使用仅与主观环境知识存在显著的正相关;新媒介中,互联网使用能够同时对客观/主观环境知识产生积极影响,手机使用与环境知识间没有显著的相关性。文章还讨论了研究发现在政策层面的意义。
Using the data of China’s comprehensive social survey in 2013, we used regression analysis to study the influence of media usage and information cognitive abilities on the acquisition of public environmental science knowledge. The results show that the use of media can improve the knowledge level of objective environmental knowledge and subjective environmental knowledge at the same time, and information cognitive ability plays a positive role in mediating between media use and objective / subjective environmental knowledge. The analysis of specific media effects shows that the use of traditional media has a significant positive effect on objective / subjective environmental knowledge, and the use of new media only has a significant positive correlation with objective environmental knowledge. There was a significant positive correlation between newspaper usage and objective / subjective environmental knowledge in traditional media. There was a significant positive correlation between magazine usage and objective environmental knowledge, and radio and television usage were only significantly positively correlated with subjective environmental knowledge. In new media , Internet use can have a positive impact on objective / subjective environmental knowledge at the same time, and there is no significant correlation between mobile phone use and environmental knowledge. The article also discusses the significance of research findings at the policy level.
