Currently，national image research is considered as one of the hottest research topics in the world，which involves rich content and covers wide range. This report aims to card the research status of national image at home and abroad，evaluate the existing research results，then discuss trends of national image research. Through combing the academic literature，we find that foreign scholars gradually use concepts and analytical paradigms in politics，psychology，communication，sociology to analyze national image. And the research content primarily covers three ways：firstly，discussing national image and its impact on foreign policy from the perspective of international relations；Secondly，concerning the relationship between the national image and business practices；Thirdly，national image research in the perspective of communication science. In China，the main purpose of national image research is to expand the international discourse and enhance the international influence. It is also the response of the real demand about “China’s peaceful rise”. So national image research in China concentrates on the fields of political science and communication studies，mainly covers three aspects，including national image’s building，the communication strategies of national image and the evaluation of national image. Looking ahead，the authors think that trends of national image research are reflected in four ways：the first is achieving cross-discipline and cross-border research，the second is achieving the unity of theoretical and practice research，the third is expanding research ideas from globalization and networking，The fourth is achieving political and scientific unity.
