Abstract: In order to analyze the impact of mass media contact on American perceptions of China's image and Sino-US relations, an online sample questionnaire survey was conducted among Americans and 2 200 samples were obtained. Multiple linear regression was used to analyze the data of the sample and it was found that:the frequency of Americans' accessing Chinese news through newspapers, television, radio, news websites and social media had no significant impact on their perceptions of China's image, but the frequency of Americans' accessing Chinese news through magazines was positively correlated with their impression of China, and the frequency of their accessing Chinese news through television, radio, and news websites had a significant impact on their perceptions of Sino-US relations. Although American mainstream media reports on China generally show a relatively serious negative tendency, the total frequency of accessing Chinese news of Americans through various media has a positive correlation with their impression of China, because the information about China that Americans get through other channels is more negative than that of the news covered by the media.
