Cultural festivals are vivid forms of urban culture. Many international cultural festivals in the world have brought worldwide reputation to the host city. In 2021，Beijing has done a lot in building a world-class brand of international cultural festivals，which meets the practical needs of building the center of international exchanges. It is an effective way to enhance the world’s understanding of China’s culture and Beijing city development. However，compared with the world-class international cultural festivals level，the international influence of Beijing cultural festivals is relatively limited，and there is still a big gap for Beijing to catch up. Therefore it is necessary to make much effort in the aspects of preliminary planning，market-oriented operation，culture mining，brand building and international communications.
