Abstract
Agenda-setting is a theory that examines the reconfiguration of the mass environment. Since 1968, when American communication scholars McCombs and Shaw began to systematically study the agenda-setting effect of mass communication, scholars around the world have conducted in-depth discussions on the topic and developed a number of theoretical hypotheses, including "attribute agenda-setting," "agenda fusion," "agenda setting by attributes," "agenda fusion," and "agenda setting by affiliated networks." To date, the concept of "agenda setting" remains a significant area of interest for scholars engaged in the study of public opinion.
