Central Business District (CBD) refers to the area where the main business activities are carried out in a country or city. Its concept first appeared in the United States of 1923, and was defined as "business gathering place" at that time. Subsequently, the connotation of CBD has been continuously enriched, and it has become the economic development center of a city, a region and even a country.
The origin of development
Central Business District (CBD) originally originated in the United States in the 1920s, which means the place where businesses meet. In the 1950s and 1960s, in developed countries, the manufacturing industry in urban centers began to move out, and business office activities continued to gather in urban centers, requiring some big cities to re-plan and build modern business centers with a certain scale on the basis of the old business centers.
Manhattan in new york, La Defense in Paris, Shinjuku in Tokyo and Central in Hong Kong are all relatively developed commercial centers in the world.
