Abstract

In this study, we investigate which factors moderate the agenda-setting influence of the mass media on the Belgian parliament during the period 1993—2000. Based on elaborate codings of the media, parliamentary questions and interpellations, party manifestos, government agreements and ministerial meetings, we employ a multi-level time-series model. The results indicate that especially party characteristics (party size, incumbent or opposition party, issue ownership) and the government agenda influence the dependency of parliament on media coverage. Furthermore, we find an increase in the extent of media influence through time, suggesting an increasing presence of 'media logic' in the behaviour of Belgian MPs. Irrespective of all those contingent factors, the mass media determine the Belgian parliamentary agenda to a considerable degree.
