The transformation of technology brings a profound change in the media pattern. It also has a great impact on the development of the news website. The national news website，as the leader of the media website，is the first to bear the brunt. It is the urgent task to assess the status of the social responsibility of each website. According to the unified construction of the new media social responsibility index system，this article takes the national news website as the research object to investigate the social responsibility performance of the 8 news websites. The analysis shows that the social responsibility of state-level news websites is generally good. XinHua Net，People’s Daily Online and CCTV（China Central Television） are ranked the top three respectively. There are still some common problems to be paid attention to，which are mainly reflected in the high degree of homogeneity of the news content，the limitation of the scope of social supervision，the single form of cultural communication，and the lack of online interaction. In view of the lack of social responsibility in the performance of various websites，the following countermeasures and promotion strategies are put forward：to create personality content and improve the quality of information production，to expand the scope of supervision and strengthen the function of social supervision，to pay attention to cultural education and innovate the form of cultural communication，to optimize the function of the platform and realize the function of coordination.
