In the process of rebuilding Dusseldorf，an important economic center in Germany，the exhibition economy played a decisive role，and Messe Dusseldorf was the main driver of this economic development. The exhibition industry is important because of its booster and the characteristics of the engine of economic development. Successful holding of an exhibition not only benefits the exhibition itself，but also benefits the exhibitors and visitors. More importantly，it will have a positive impact on the market，economy and society. One of the reasons why Messe Dusseldorf has become a leading company in the industry is its unique business characteristics-regional operation，integrated operation，and classified operation. Each business strategy brings high efficiency to the development of the company. In addition to its own business results，the government’s various forms of support for the exhibition industry are also the reasons for the achievements of Messe Düsseldorf. With the development of the times，the exhibition industry is no longer limited to products，buyers and sellers，it will connect more industries and more regions. With the development of multi-industry integration，the exhibition industry has brought many growth points to the German economy，which can be reflected vividly by the data. Messe Dusseldorf and even the successful road of well-known exhibition enterprises in Germany have provided many effective paths for the development of China’s exhibition industry.
