论文摘要
本文研究了媒体倾斜的扩散。我们记录了FOX新闻频道（FNC）对1995 - 2008年美国当地报纸的党派倾向的影响。我们通过将新闻文章的文章扩展到国会中的共和党和民主党的演讲来衡量当地报纸的政治倾向。使用渠道定位作为观众的工具，我们发现较高的FNC收视率会导致当地报纸采用更多的右翼倾斜。 FNC介绍仅几年后，这种效果逐渐出现，反映了该频道对投票行为的不断增长。报纸上转变的主要驱动力似乎是当地政治偏好的变化。
This paper examines the diffusion of media slant. We document the influence of Fox News Channel (FNC) on the partisan slant of local newspapers in the U.S. over the years 1995-2008. We measure the political slant of local newspapers by scaling the news article texts to Republicans' and Democrats' speeches in Congress. Using channel positioning as an instrument for viewership, we find that higher FNC viewership causes local newspapers to adopt more right-wing slant. The effect emerges gradually, only several years after FNC's introduction, mirroring the channel's growing influence on voting behavior. A main driver of the shift in newspaper slant appears to be a change in local political preferences.
