媒介使用與滿足說是近年相當受重視的傳播理論假說。本研究欲以此說為基礎，來比較中美人民的媒介暴露、滿足尋求、是否避免媒介內容與其國際政治知識的相關程度。結果發現中美受測者閱讀報紙的時間與其國際政治知識的多寡無關，但中國人收視電視時間與其國際政治知識呈正相關。對美國受測者而言，其滿足需求與各種新聞的收視和其國際政治知識呈正相關，亦即其愈有媒介的需求，愈會從各種不同媒介內容中尋求滿足，而國際政治的知識程度愈高。但對中國受試者而言，使用滿足說、媒介暴露與其國際政治知識的多寡之相關並不清楚，值得更進一步的探討。As a postindustrial society, the United States has one of the most developed media systems in the world. Taiwan, on the other hand, is a deveoping country with a remarkable success in the economic and social development which contribute to the establishment of a "media-rich" society. This study attempted to examine the media exposure, gratifications sought and avoidance behavior considered relevant to international political knowledge of 225 American residents at Chicago and 234 Chinese living at Taipei, Taiwan. One purpose of this study was to explore empirical aspects of the media uses and gratifications typologies related to international news in the United States and Taiwan. A factor analysis had produced three factor solutions for both samples, which were labelled avoidance, communication utility and surveillance. This study also hypothesized that media use, gratifications and avoidances of international news was related to levels of knowledge of international affairs. This study found no relationship between respondents' newspaper exposure time and their knowledge of international affairs for either sample. But there was a positive relationship between Chinese respondents' television exposure time and the international political knowledge. The results appeared to coincide with the findings of McLeod et al. and Becker, who suggest that media gratifications and avoidances are not merely surrogates for media use or exposure. This study confirmed that gratification needs predicted the exposure of various kinds of news and knowledge positively and avoidances in the opposite direction for the American sample, but not for the Chinese sample.
