1. Commercial complexes have a high degree of complexity of business functions and transportation networks, generally complexes have a variety of commercial, office, cultural and entertainment, residential and other functions, accordingly, there will be shopping centers, residential (or serviced apartments, hotels), offices (or SOHO) and other full range of businesses.

2. Efficient use of time, land and resources, because the high degree of complexity of functions and transportation naturally allows the most efficient use of time.

1. Commercial complex: derived from the concept of "urban complex", but there is a clear difference between the two. Commercial complex, is the city of business, office, residential, hotels, exhibitions, restaurants, conferences, recreation and other urban living space, more than three functions for the combination, and the establishment of a kind of interdependence between the parts, mutual benefit of the dynamic relationship, so as to form a multi-functional, high-efficiency, complex and unified complex.

2. The main features of commercial complex:

External features:

(1) high accessibility;

(2) high density and intensification;

(3) overall unity;

(4) functional composability;

Internal features:

(1) large spatial scale;

(2) access tree shape;

(3) high efficiency, complex and unified. p>(2) channelized tree-shaped transportation system;

(3) modern urban landscape design;

(4) high-tech integrated facilities.

3. The role of commercial complexes:

With the development of the city, commercial complexes came into being. It is a building complex formed by combining several building spaces with different use functions, and its rationality lies in saving land, shortening transportation distance, improving work efficiency, and exerting investment benefits.

4. Categories of commercial complexes:

Commercial complexes are generated out of the need for a high degree of intensification of urban land resources, so its core area in the city and the future core area, the specific location can be roughly divided into four categories: the central business district of the new development zone, the city's sub-center, the CBD and transportation hubs.

5. The direction of the development of business complexes:

(1) Theoretical research on building complexes has gradually deepened. From the past to some of the traditional study of regional economics, gradually shifted to the monolithic building, the overall in-depth study of the composite building. Mainly manifested in three pieces: the first piece is the existing professional research team: the second is in the university, the research on the theory of composite: the third is the study of returning school scholars. Urban complex is the development direction of China's reform and opening up.

(2) From the practice, three forces emerged. The first force is the gradual development of a new type of urban commercial complex with large shopping centers as the carrier. The second force is the leisure complex and tourist facilities complex, as well as office complexes with office buildings as the main body, and there have been some attempts all over the country. For example, like CITIC City Plaza, Vientiane City is predominantly commercial. There has been a creative real estate-based complex supporting the mainstay of entrepreneurial real estate complexes.

(3) The emergence of a group of specialized firms that focus on urban commercial complexes, unlike traditional real estate consultants. The biggest difference between commercial complexes and traditional real estate is that it requires an understanding of the different levels of commercial development levels and different forms of commercial construction in the regional business, as well as the function of the business.
