Hong Kong resorted to high-rise buildings and skyscrapers due to the imposing challenge of limited land available for new buildings. This was driven by a huge population and a rapidly rising economy that required a great deal of commercial real estate to be developed. Evolutions in modern architectural designs that allowed for the construction of such tall buildings was also a key factor in this construction pattern. As such, there was a deliberate government policy to build skyscrapers in order to meet the challenge of unavailability of land for new developments. Today, Hong Kong is the city with the highest numbers of skyscrapers and high-rise buildings of any in the world. It also showcases some of the most internationally applauded contemporary architectural designs within them, and is therefore a tourist destination for many who appreciate great architecture.

The majority of international organizations, such as the CTBUH and Emporis, define a skyscraper as a building that reaches or exceeds the height of 150 metres. The top four cities with the most skyscrapers are:

Hong Kong with 315 skyscrapers 150m or above.

New York with 243 skyscrapers 150m or above.

Dubai with 153 skyscrapers 150m or above.

Shanghai with 148 skyscrapers 150m or above.
