The national strategy of "Guangdong - Hong Kong - Macao Greater Bay Area" has replaced the original Pearl River Delta economic circle. As one of them, the economic development of Zhaoqing City ushered in a historic opportunity. Other cities in Greater Bay Area provide sufficient tourist resources for the development of Zhaoqing's tourism industry. Under the new situation, Seven Star Cave, the leading scenic spot in Zhaoqing, should firmly grasp the national strategic dividend of the "Guangdong - Hong Kong - Macao Greater Bay Area", accelerate the transformation and upgrading, and enhance the market competitiveness. In this paper, the data are collected by nominal group technique, and are integrated into SWOT matrix for analysis. The development strategy of Zhaoqing Seven Star Cave Scenic Area is obtained by matching internal and external factors. [ABSTRACT FROM AUTHOR]
