Industrial tourism is an important means of new industrialization and urban transformation，and it is also a new field of integrated development of tourism. The Guangdong-Hong Kong-Macao Greater Bay Area has a long industrial history and rich industrial tourism resources，with regional characteristics and advantages. However，the types of industrial tourism products in the Guangdong-Hong Kong-Macao Greater Bay Area are homogenous，lacking cross-regional resource integration and theme routes. The display and interpretation of the particularity of industrial history and culture are insufficient. Based on this，this study puts forward three suggestions for the future development of industrial tourism in the Guangdong-Hong Kong-Macao Greater Bay Area. First of all，a comprehensive display should be carried out according to the characteristics of the product. On the one hand，it should adopt a variety of presentation and explanation methods，and on the other hand，it should pay attention to the inheritance and display of intangible cultural heritage. Secondly，establish an effective connection between industrial tourism and tourists through popular science and education. In order to enhance the cultural，informative and interesting of tourism experience. Finally，mobilize the enthusiasm of industrial enterprises to develop tourism through policy guidance and improve the management and service level of enterprises so that enterprises can deeply explore industrial civilization，excavate the spirit of craftsmen，and tell the industrial history stories of the Guangdong-Hong Kong-Macao Greater Bay Area.
