What is the city CBD?

Urban CBD refers to the central business district of a city, which refers to the area where major commercial activities are carried out in a country or a big 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 central business district is the symbol and symbol of urban modernization, the functional core of the city, and the intensive area of urban economy, science and technology and culture.

CBD is mostly located in the main core area of a country or region, where there are all kinds of first-class buildings and perfect public facilities, such as Grade A commercial buildings, shopping malls, government and public institutions, entertainment facilities and so on. In addition, the traffic accessibility in this area is extremely high, and highways, railways, ports and airports are all located in convenient locations around this area, making it extremely convenient for citizens to travel between regions.

CBD generally covers an area of 3 to 5 square kilometers, and some are even larger, with a total construction area ranging from five to six million square meters to tens of millions of square meters. CBD is not only the functional core of a city, but also an important symbol of a modern metropolis, and its central land price is often much higher than that of the surrounding areas of CBD.

There is a business center in Sydney, and the business centers in Hong Kong are in Central and Tsim Sha Tsui. The United States and Canada call the central business district "urban business district", because in the past, residential areas were all on the mountain and shopping streets were all under the mountain. Japan and South Korea call CBD "capital" or "busy street".
