This research adapted and extended relationship quality scales and measurements developed in various B2B or B2C contexts in Western countries to the exhibition context in Mainland China. Results indicate that in the exhibition context, where exhibitor recruitment and the provision of facilities/amenities become increasingly homogenous among competitive exhibitions/ organizers/destinations, relationship marketing might play an important role in creating long-lasting exhibitions. Cultivating a long-term relationship orientation with exhibitors shall be critical for exhibition organizers for the successful and sustainable development of exhibitions. In designing this study, considerable efforts were made to minimize its limitations, and particularly ensure its representativeness by sampling altogether 10 exhibitions in two first-tier cities and four second-tier cities in two regions where exhibitions are most developed, and thereby covering international and national exhibitions of diverse ownerships and varied industry sectors, staged in venues in both first and second-tier cities over a period of four months.
