Fundamental Study on the Media Ecology in the 21th Century Information Society

为了探讨多渠道信息环境下地方信息媒体的实际使用情况，我们对约纳戈市20-69岁的819名市民进行了社会调查。我们询问了受访者对电视、报纸、有线电视和其他当地媒体的接触情况以及互联网的使用情况。我们还对中开有线电视公共频道的工作人员进行了集体采访。此外，我们还根据10名左右的学生的谈话录音和电子邮件交流，继续进行了“经济交流”的会话分析。(1)从电视和互联网的使用和满足的结构是有点相似和功能上的替代。(2)订阅有线电视最强烈的动机是多频道环境和专业节目，这意味着对多频道电视的强烈需求。(3)中海电视台的社区频道在观众中相当受欢迎。地震新闻、选举投票率报告、年度社区节日等以当地事件为导向的节目尤其受欢迎。(4)虽然公众频道的收视率不高，但许多人都曾接受过中央电视台的地方原创节目的采访或接触，这对社区的发展有积极的作用。通过对经济台语音对话和电子邮件的对话分析，发现人们使用各种面部标记或图标来表达感情。研究还发现，通过手机通信发送的电子邮件信息简短、随意，在短时间内移动时频繁交换，体现了移动的通信媒介的特点。
