How parties respond to protests in a changing political landscape
研究1975至2019年德国环境与极右翼抗议如何影响政党议程，发现抗议的议程设置效应微弱，但极右翼暴力引发辩论，且被制度盟友（德国选择党）进入议会所抑制。
Can protests set the political agenda by compelling parties to respond to protesters’ grievances? Or do parties avoid engaging with these grievances by raising concerns about political violence and ideological extremism? And is this response affected by the parliamentary entrance of an institutional ally? This paper addresses these questions by studying the effect of environmental and far-right protests on parties’ parliamentary agendas in Germany from 1975 to 2019. Using a regression discontinuity in time design, the paper finds little support for protests’ agenda-setting effect. However, far-right protests’ use of violence and confrontation spark a debate about far-right violence. However, this effect seems to be dampened by the entrance of institutional allies; the AfD's entrance to parliament is followed by a limited responses from other parties to far-right protests. Overall, the findings enhance our understanding of the political consequences of protests and underline the importance of drawing on insights from party research when studying political elites’ responsiveness to protests.
