Based on a nationwide survey, this study examines the mediated constructions of political ideology and its antecedents in contemporary China. The empirical findings offer insights into China's future by examining political beliefs in the country. Our study found that most of the respondents share an inclination toward Liberalism, indicating that the general public harbors expectations not only for expansion of market competition to ensure the country's successful entry into the world economic system in the age of globalization, but also for deepening political reforms, increased supervision of political power, and growing access to democratic participation. The study also investigated the relationship between media use and political ideology, as the former, together with new technology, predicts the latter to varying degrees. In addition, social psychological factors such as the motivation to use the Internet and trust in media were found to play significant roles in these complex relationships. Individuals' social interactions and their political cognitions also help to explain the complexity of political ideology in a transitional society.
