媒介使用、信息认知能力与公众的环境科学知识获取——基于全国代表性数据的实证研究

Media use,information cognitive ability and the public's environmental science knowledge acquisition——Empirical research based on national representative data

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。

Based on Chinese General Social Survey 2013 data,the article studies the impact of media use and information cognitive ability on public＇s environmental science knowledge acquisition using regression analysis. The results show that the media use can improve the level of objective environmental knowledge and the subjective environmental knowledge at the same time,and information cognitive ability is the moderator between media use and the objective/subjective environmental knowledge acquisition. Specific media effects analysis shows that traditional media use has significant positive effects on objective/subjective environmental knowledge at the same time,while new media use only has a significant positive correlation with objective environmental knowledge. Among the traditional media,newspaper use has a significantly positive correlation with both objective and subjective environmental knowledge,while magazine use only has a significantly positive correlation with objective environmental knowledge,and radio and television use only have significantly positive correlation with subjective environmental knowledge; among the new media,Internet use has significant positive effects on objective/subjective environmental knowledge at the same time,and cellphone use has no significant correlation with environmental knowledge. The article also discusses the significance of the research findings at the policy level.
