日本のブロゴスフィアにおける政治系有名ブログの影響―2007年参議院議員選挙時の内容分析から

Abstract

This study into the Japanese blogosphere examined the sources used by Japanese A-list political blogs, the sources' influence on the attitude of the A-list bloggers, and the influence of A-list blogs on the attitude of other bloggers. A content analysis of 47 A-list political blogs during Japan's 2007 Upper House election campaign found that A-list blogs considerably depended on mainstream media as sources. 44.8% of these mainstreams sources were accounted for by newspapers, with online news making up another 39.3%. The analysis also found upon an examination of opinions regarding the Liberal Democratic Party that few news items in mainstream media expressed political opinions, whereas most blog items did. The low degree of coincidence between the political opinions of A-list blogs and those in mainstream media suggests there was no influence from these sources on the attitude of A-list bloggers. On the other hand, there was a statistically significant coincidence between the political opinions of A-list blogs and the ones of blogs that cited A-list blogs. Nevertheless, this importance of this coincidence should not be over-emphasized, as the majority of blogs analyzed expressed negative opinions regarding the Liberal Democratic Party in any case.
