The innovative concept of “smart tourism” was put forward in 2010. The former National Tourism Administration has designated 2014 as the “Year of Smart Tourism” as the theme of China’s tourism，indicating the official arrival of the era of smart tourism in China. In recent years，with the continuous integration and development of cultural and tourism industries，the transformation of smart technologies such as 5G communication，artificial intelligence，big data，VR/AR，blockchain，and Internet of Things has become an important engine to optimize the transformation and upgrading of cultural and tourism industries. Through deepening “Internet + tourism”，we should build a digital tourism economic system represented by Internet technology，and then promote China’s tourism to the stage of high-quality development. Smart tourism has become the key path to bridge the cultural and tourism economic gap caused by the epidemic. It plays a positive role in epidemic prevention and control as well as economic and social development，shows strong growth potential，and becomes a new driving force for high-quality development of the cultural and tourism industry. Smart cultural tourism will undoubtedly become an important direction of the transformation and upgrading of the post-epidemic cultural tourism industry.
