Guangzhou is a traditional tourism city in China. In recent years，with the rapid development of tourism in cities across the country，urban tourism in Guangzhou has faced many challenges and competitions. In the context of the construction of the Guangdong-Hong Kong-Macao Greater Bay Area，tourism in Old Guangzhou needs to seek new development. Through an overall analysis of Guangzhou’s urban functions and status，theme characteristics and core elements of the tourism construction，this study evaluated its comparative advantages and analyzed its specific impact on the total amount and structure of Guangzhou’s urban tourism，so as to find the key areas of Guangzhou’s urban tourism development，focus on making up for the shortcomings，focus on the potential of development. The research pointed out that the development of Guangzhou’s urban tourism should have a higher pattern and a higher positioning. It is necessary to find Guangzhou’s position in the global tourism industry along the “One Belt and One Road”，to find a position from the future layout of China’s national central cities，from the scale，structure，and function of the core cities in the Guangdong-Hong Kong-Macao Greater Bay Area. The paper suggests that Guangzhou should further enhance the status and functions of the city，accelerate the construction of core elements of tourism with the attractiveness of the medium and long-range markets，reshape and innovate the theme image and spatial carrier of Guangzhou urban tourism，and consolidate and improve the quality of the development of Guangzhou’s urban tourism related industries，to explore and develop new markets and new formats of urban tourism in Guangzhou，and to attach importance to and develop the urban tourism needs of local and surrounding residents.
