The literature suggests that advances in information and communication technologies have been a major driver of the restructuring of multinational enterprises and their cross-border supply chain management. However, the role of information technology usage for collaboration and its antecedents and performance implications in cross-border exchange relationships have not been clearly specified. In response to this claim, this study examines the determinants of electronic collaboration (E-collaboration) and its outcomes for suppliers with regard to their international customers. Drawing on an empirical foundation of 240 Taiwanese-based electronics equipment manufacturers, we test the effects of technological, organizational and environmental dimensions on E-collaboration and its impact on relationship performance in international exchange. The findings on the pertinence of E-collaboration in international customer–supplier relationships are presented and discussed.
