Whether supply chain collaboration and inter-firm trust has a positive impact on logistics performance is still a subject of debate in the literature. This ambiguity has raised concerns among academics and practitioners. Therefore, we empirically examine the impact of supply chain collaboration and inter-firm trust on logistics performance. We first explore a real tourism supply chain to specify main factors and propose hypotheses. We then statistically test the hypotheses using data from six cases and a survey of 109 firms. The results show that, by establishing joint activities with their partners, firms could significantly improve their performance.
