The COVID-19 outbreak in early 2020 has caused a significant impact on the cultural and tourism industry. In response to the pandemic and the resultant industry’s plight，governments in the Guangdong-Hong Kong-Macao Greater Bay Area （GBA） have formulated a series of supportive policies. In this paper，we analyze the text of the supportive policies extracted through official channels such as the portals of the relevant departments of the municipal governments in GBA，and explore the types and content characteristics of the supportive policies for cultural and tourism industries in nine mainland cities in GBA through the lens of policy tool analysis and textual analysis. We found that the policy tools for cultural and tourism industry support in the GBA cover supply-based policies，environment-based policies and demand-based policies，with supply-based policies and environment-based policies dominating and the structure of policy tools being unbalanced. The main body of policy formulation is the municipal cultural and tourism bureau，and the collaboration between different government departments and multiple actors needs to be strengthened. The cultural and tourism industry supportive policies of different city have both commonality and differences reflecting local characteristics，but there is a lack of coordination and cooperation between different cities，and the co-construction and co-governance of tourism destinations in the Greater Bay Area has yet to be realized.
