In the development of China's urban economy, all economic activities that use newly developed buildings and idle houses in urban areas to attract investment and introduce modern service enterprises and urban industries through leasing, selling and cooperation, so as to cultivate new tax sources and new economic growth points and promote urban economic development are collectively called building economy.

In recent years, the business opportunities and energy contained in various new economic terms such as headquarters economy, sports economy, community economy and training economy have brought "surprises" to the government and savvy businessmen again and again. At this time, a new economic form has emerged quietly in the metropolis, attracting more and more "eyeballs", which is the building economy. The formulation of China's building economy began in 1990s, which is a compound concept put forward by economists. The concept and practice of building economy first appeared in Shenzhen and Shanghai, and then in some economically developed coastal cities (Ningbo, Fuzhou, Dalian, Tianjin, Wuxi, etc.). ), and more and more accepted by other city governments. In recent years, the central urban areas of some cities have taken the development of building economy as a new development measure, actively promoted it and achieved certain results. The rise of China's building economy is not an accidental phenomenon, but a natural economic phenomenon in which China's city and social economy have developed to a certain stage.

Building economy refers to the use of newly developed buildings and idle buildings in urban areas, taking commercial buildings, office buildings, scientific research buildings, standard factories, urban complexes, protected buildings and rural self-employed households (excluding buildings occupied by administrative institutions, hotels, professional markets, hospitals, schools and other buildings) as carriers, attracting investment to introduce modern service enterprises and urban industries through leasing, selling and cooperation, and cultivating new tax sources and new economic growth points.

Building economy is an advanced economic form that gathers the headquarters of modern service industry and manufacturing enterprises. It can gather considerable talent flow, capital flow and information flow in very dense space, create continuous employment and tax revenue, and produce obvious wealth effect and land-saving effect.
