This study explores how humanitarian organizations (HOs) link donors and recipients in a disaster relief coordination mechanism. Based on an analysis of real data collected from the financial tracking service, our results show that disaster assistance through the HO channel greatly exceeds the funding delivered by the non-HO channel. The severity of the disaster is positively correlated with the involvement of HOs. Disaster-stricken countries that belong to the Non-Aligned Movement receive more assistance through the HO channel. The recipients with less international trade may attract more HO-channel funding, but higher international tourism expenditures also may result in more HO-channel funding. We also found that the determinants of the disaster relief coordination path vary greatly in terms of trade openness, political regime, and geographic factors. Based on the analysis of the primary humanitarian relief supply chain, the results show that some countries prefer to donate through large international HOs (e.g., Japan and Canada), and other countries favor national level organizations (e.g., the UK and the USA). Finally, to improve the efficiency of international disaster relief, the paper suggests a coordination platform that involves the main donors, frequent recipients, HOs, and a Global Information Network that can assist in coordinating disaster relief activities.
