Replication Data for: Issue Ownership and Agenda Setting in the 2019 Swiss National Elections

The 2019 Swiss national elections were characterized by the unusual prominence of two issues, environment and gender, whereas two staples of Swiss politics, immigration and Europe, were less dominant compared to previous elections. We study how, in this context, the media and party agenda were linked to issue ownership. Specifically, we consider whether political parties that own an issue could lead the media agenda and the agenda of other parties. Our analysis relies on all tweets and press releases of major Swiss political parties from January to October 2019 and 37,225 newspaper articles published during the same period. Results show, first, that the agenda-setting capacity of parties was restricted to the gender issue, and second, that the link between issue ownership and agenda setting is ambiguous. These findings suggest that during election campaigns, agenda setting may be largely exogenous to both parties and media.2019年瑞士全国性选举呈现出一项异乎寻常的特征：环境与性别两大议题获得了远超以往的关注度；而瑞士政坛历来的两大核心议题——移民与欧洲相关议题——的影响力则较往届选举有所削弱。本研究旨在探究在此语境下，媒体议程与政党议程如何与议题归属权（issue ownership）产生关联。具体而言，本研究将检验拥有某一议题归属权的政党，是否能够主导媒体议程以及其他政党的议程。本研究的分析样本涵盖2019年1月至10月期间瑞士主要政党发布的全部推文与新闻稿，以及同期刊发的37225篇报纸文章。研究结果显示：其一，政党的议程设置能力仅局限于性别议题；其二，议题归属权与议程设置之间的关联仍不明确。上述研究结果表明，在选举竞选期间，议程设置在很大程度上外生于政党与媒体双方。
