With the promulgation and implementation of the Guangdong-Hongkong-Macao Greater Bay Area Development Planning Outline and the continuous deepening of Macao’s “constructing a world tourism and leisure center” expectation，Macao’s convention and exhibition，tourism and hotel industries have ushered in an unprecedented opportunity for development. Based on the statistical data and the development status analysis of Macao’s convention and exhibition，tourism and hotel industries，this paper finds that in recent years，relying on the economic and trade cooperation service platform between China and Portuguese-speaking countries，Macao，the world’s largest gambling market and the world’s first-class commercial complex，continuously improves the character of ecological livable city under the intersection of Chinese and Western cultures，and creates a “charm city” focused on characteristics with cultural heritage and creation and promotes the development of international tourism education and training，convention and exhibition market，yacht market and other emerging industries. At present and for a period of time in the future，Macao needs to speed up its integration into the Guangdong-Hongkong-Marco Greater Bay Area，continuously optimize the supply quality of convention and exhibition，tourism and hotel industries，and develop its overseas markets，so as to solve the problems such as the existing industrial space，promoting moderate diversified development of the industry，enhancing the stickiness of merchants，improving the ability of industry undertaking and receiving customers，breaking through the integration of resource elements of convention and exhibition，tourism and hotel industry in Guangdong，Hongkong and Macao.
