Abstract: Using the data from 652 enterprises in 2007-2011 and the Heckit model,we analysed the behaviors of enterprises' exhibition participation and booth area selection. The results suggest that:distance,whether the exhibition is itinerant and the enterprise's scale/foundation period/revenue all have impact on enterprise's exhibition participation. Consider all the factors mentioned above,revenue is the key factor that have impact on enterprise's booths selection. It's interesting that when we only consider the enterprises that attended in the exhibition,we find that the exhibitors that is far away from the exhibition location will choose more booths. One possible reason for this phenomenon is those exhibitors want to choose more booths to offset the cost that caused by the long distance.
