Despite the fact that conflict is an essential behavioural dimension underlying the buyer-seller relationship, no empirical work has as yet been conducted on the comparison of conflictual processes between different types of marketing channels. This paper attempts to compare exporter-importer and exporter-domestic customer business partnerships, regarding the dimension of conflict throughout its various stages of growth and development. The study was carried out on a sample of 53 indigenous Greek manufacturing firms. Contrary to prior expectations, it was found that the exporter-importer (E-I) kind of relationship was not characterized by higher levels of conflictual processes than those in the domestic type of business association. Surprisingly, the study results also showed that in a substantial number of conflict areas, the domestic relationship category was governed by significantly higher levels of conflictual processes compared with those in the E-I kind of business partnership. The managerial implications of the research findings are discussed and avenues for future research directions are outlined.
