2010-2016年公共议题的公众注意力周期变化研究
Exploring Duration of Public Attention from 2010 to 2016
公众对于公共议题的注意力周期,是评估公共话语建构的重要维度。本研究通过 对2010至2016年间公众对121个公共议题注意力周期的分析,揭示了近年来公共议题中 的公众注意力的变化规律。研究发现,公众对议题的关注周期在缓慢但显著地缩短; 即使加入了事件类型、同期热门事件数等控制变量后,议题注意力周期逐渐缩短的变 化趋势仍然显著。本研究扩展了“公众注意力”的定义,进而拓展了公众对公共议题 关注度基于单一时间节点的研究视野,并聚焦于公众议题的时序变化模式。本研究对 新媒体环境下的议程设置理论研究具有启发和开拓意义。
Duration of public attention on certain issues is an important metric to evaluate quality of public discussion. This study, employing public search records of 121 public issues on search engines from 2010 to 2016, reveals that the duration of public attention has been slowly but signifcantly shortened in the past seven years. Even after controlling variables, including event type and number of popular events, the decreasing trend of public attention is still signifcant. This study expands the conceptualization of "public attention", which further widens the research horizon of public attention on public issues. This study is of enlightening and pioneering signifcance for exploring agenda setting theory in the era of new media.
