本文以“报料信息内容”、“媒体呈现的报料内容”及“报料人群体抽样调查”三部分资料为基础,以时间序列分析技术对报料信息和媒体呈现内容关系进行了分析,研究发现,报料人群体是公众中积极参与媒体议题建构的群体,他们具有显著的设置议题意识,但是参与议题建构的能力有限,原因之一是多数报料人将媒体视为可借助解决来自草根阶层社会问题的工具。报料信息经过媒体把关人的严格判断和挑选才可能进入媒体议题,这种挑选并非按照各类信息报料的多少来确定,而是根据是否具有“新闻价值”来判断。报料人群体参与建构媒体议程的目标能否实现,要看各媒介组织自身的定位和媒体框架。 Based on the three parts of “information content ”, “contents of the media ” and “sample survey of referees ”, this paper uses the time series analysis technology to report the retribution information and the media Content relationship, the study found that referees groups are the public who actively participate in the construction of media issues groups, they have a significant set of issues awareness, but the ability to participate in the issue of construction is limited, one of the reasons is that most of the referees to the media Think of tools that can help solve social problems from the grassroots. Newspapers information through the media before the strict judgment and selection of people may enter the media issues, this selection is not in accordance with the size of all kinds of information to determine, but based on whether the “news value” to judge.
