Guangdong-Hongkong-Macao Greater Bay Area is the frontier of China’s reform and opening up，and has an important strategic position in the overall national development. The report “19th National Congress” of the Communist Party of China pointed out that we should comprehensively promote mutually beneficial cooperation between mainland China，Hong Kong and Macao，focusing on the construction of the Greater Bay Area of Guangdong，Hong Kong and Macao，and the regional cooperation in the Pan Pearl River Delta. The relationship between the cities in the bay area is getting closer and closer，and the tourism economic connection of each city is gradually increasing. The overall tourism economic network structure is in a sound development.
