Second, the development of secondary cities

1, pay attention to the cultivation of exhibition organization system. Under the current economic management system in China, holding exhibitions requires not only the operation of exhibition companies and the participation of enterprises, but also an authoritative organizational structure. Among them, government departments have played a great role in the invitation, publicity, approval and cooperation of exhibitions. ?

Second-tier cities usually lack the advantages of developing convention and exhibition industry, so they should seek extensive support from projects and higher-level governments and international cooperation. ?

2. Pay attention to the topic planning of the project. The topic planning of an exhibition is very important, which ultimately determines the success or failure of the exhibition project. Once the topic is wrong, even the best operation team will not succeed.

Because many secondary cities look too far, they often imitate the operation mode of internationally renowned exhibitions or big cities, and the result is often short-lived, which not only fails to achieve the expected goal, but even runs counter to it.
