中文摘要：

农民工网站是现阶段我国农民工信息服务保障体系的重要组成部分,对农民工网站的运营机制进行研究可以为提高其运营效果提供依据。本文以信息构建（IA）理论、技术接受模型（TAM）及技术接受与利用整合模型（UTAUT）、可用性理论与网站价值理论为引导,采用多案例研究方法对我国目前正常运行的所有12家农民工网站进行了分析,构建了农民工网站运营机制模型。研究发现由政府主办或支持的公益性网站数量所占比重最高,商业性网站次之;网站的经营性质、信息质量、信息构建水平与宣传推广力度影响网站运营效果;目前农民工网站在满足农民工信息获取需求方面发挥了较好的作用,但在满足农民工信息表达需求方面还有待提高。
