While social networking sites (SNSs) have become popular news platforms where people receive and post news, little is known about why some people are relatively more active in receiving and posting news on SNSs. Based on the uses and gratification perspective, this study investigates (a) the direct and indirect effects of online news seeking on SNS news posting, through SNS news exposure, (b) the role of technology adoption as a moderator between online news seeking and SNS news exposure, and (c) the role of media bias perceptions and partisanship strength as moderators between SNS news exposure and SNS news posting. Analysis of 2010 Pew Research Center Media Consumption Survey data (N = 2,259) reveal that online news seeking significantly predicts SNS news posting, both directly and indirectly. While technology adoption was not a significant moderator, media bias perception and partisanship strength significantly interacted with SNS news exposure in predicting SNS news posting.

为什么人们在社交网站上发布新闻

虽然社交网站 (SNS) 已成为人们接收和发布新闻的热门新闻平台，但人们对为什么有些人在 SNS 上接收和发布新闻相对更积极的原因知之甚少。基于使用和满足的角度，本研究调查了 (a) 通过 SNS 新闻曝光，在线新闻搜索对 SNS 新闻发布的直接和间接影响，(b) 技术采用作为在线新闻搜索和 SNS 之间调节器的作用新闻曝光，以及 (c) 媒体偏见认知和党派力量作为 SNS 新闻曝光和 SNS 新闻发布之间的调节器的作用。对 2010 年皮尤研究中心媒体消费调查数据 (N = 2,259) 的分析表明，在线新闻搜索直接和间接地显着预测了 SNS 新闻发布。
