中文摘要
本文考察媒体报道对移民态度的影响。文章将法国电视中的移民报道数据与2013年至2017年的个体面板数据相结合，后者记录了受访者偏好的电视频道及其对移民的态度。分析聚焦于个体内部随时间的变化，以处理受访者基于意识形态的频道自选择问题。我们发现，移民报道的增加使态度趋于极化，原本态度温和的个体更有可能报告极端正面或极端负面的态度。这种极化主要由移民议题凸显性的提高所驱动，凸显性的提高重新激活了既有偏见，而非由接触有偏向的新闻所产生的说服效应驱动。（JEL D83, D91, J15, J18, L82）
Abstract
This paper investigates the effect of media coverage on immigration attitudes. It combines data on immigration coverage in French television with individual panel data from 2013 to 2017 that records respondents' preferred television channel and attitudes toward immigration. The analysis focuses on within-individual variations over time, addressing ideological self-selection into channels. We find that increased coverage of immigration polarizes attitudes, with initially moderate individuals becoming more likely to report extremely positive and negative attitudes. This polarization is mainly driven by an increase in the salience of immigration, which reactivates preexisting prejudices, rather than persuasion effects from biased news consumption.
