CSD( Central Shopping District), that is, the central leisure shopping area, is a popular gathering area of non-central cities, an inevitable trend to solve the sustainable economic development of big cities, and a part of "polycentric development" urban planning. Central Leisure Shopping District (CSD) is generally located in the transportation hub between cities, with theme parks, tourist resorts, super-large commercial centers, gambling and other formats as the economic core, and is an intercity center integrating commerce, information, culture, exhibitions, hotels, restaurants, leisure and office.

Second, the conditions for the development of waterfront economy:

1, excellent geographical location:

Changyang Town is the starting area of "CSD Fangshan Central Leisure Shopping Area" and an important part of "Yongding River Green Ecological Corridor Construction Plan".
