The paper traces the origin of Hong Kong’s CBD from the early 1960s through examining the composition of its employment，landuse and boundary changes. It puts emphasis on the district’s high connectivity by major public transport with the rest of the city which offers it high acessarbility，and on its nodal position and free port status in Asia-Pacific area. China’s Open and Reform policy and the rise of the Asian economies in the 1980s have driven its further rapid growth in recent decades. The paper also points out that Hong Kong’s CBD has grown around its financial core，and that the co-location of the CBD and the government headquarters has benefitted the CBD. These are some of the aspects worthy of attention by Mainland governments in planning CBD development.
