The government’s image-building projects can not do without the new media to adhere to social responsibility. Related research is conducive to improve the public’s trust in government. This empirical research on college students found that Chinese government image showing a “pyramid” structure，the evaluation of the central government’s ruling ability is higher than the local government. Although the image evaluation of China’s national leaders are good，the image of ordinary civil servants still need to make a positive effort. In addition，media contact affects the cognition of college students about the image of our government，the frequency of media contact and the degree of trust are present positive correlation. The traditional media continue to lead the new media in the “authority” and “depth”，however，the penetration and influence of new media are far higher than the traditional media. Media must assume their social responsibility to shape a good image of the government. As a new force of medium，the new media is easily become a source of the government image crisis，and it can easily become the “fire extinguisher”in government image crisis. In the process of shaping the image of the government，the new media must take the responsibility to guide public opinions.
