Under the background of the construction of Guangdong Hong Kong Macao Great Bay area, there are a large number of underutilized “sleeping resources” in the region, which restricts the overall efficiency improvement and the coordinated development of urban and rural areas. Based on the reality of Dawan District, this paper defines the narrow and broad connotation of sleeping resources, and divides its system into four categories: culture, nature and ecology, economy and industry, and society and space from three dimensions: value attribute, sleeping state and regional characteristics. It then analyzes its three characteristics of value diversification and concealment, spatial cluster and cross-border, regional strategy and urgency. Combined with the development trend of digital economy, it puts forward the innovation strategy of resource activation, in order to provide theoretical reference and practical guidance for the resource integration, value release and high-quality coordinated development of Guangdong Hong Kong Macao Greater Bay area.
