Estimating of efficiency based on different modes of transportation for OECD countries : bootstrap DEA

Background: The purpose of this study is to compare transportation efficiency across four modes of transport for OECD countries, considering key operational factors affecting efficiency, as well as environmental and economic perspectives. Methods: This study employs the bootstrap Data Envelopment Analysis (DEA) approach to evaluate the performance of OECD countries' transportation sectors. Bias-corrected efficiency scores are used to ensure more robust and consistent results in cross-country comparisons. Results: The findings reveal that the most efficient countries vary by transport mode (road, sea, rail, and air). Road transport exhibits the lowest average efficiency score among OECD countries, while rail transport exhibits the highest. For road transport, Canada, France, and the United Kingdom have high-efficiency scores with low bias values, while Iceland attains a bias-corrected full efficiency score without bias. In maritime transportation, Canada, Australia, Finland, and Germany achieve high-efficiency scores. For rail transport, the most efficient countries are Australia, Canada, Greece, and Luxembourg, while for air transport, Canada, Chile, and Latvia exhibit high-efficiency bias-corrected scores. The study also identifies that reducing carbon emissions and increasing infrastructure investments are key factors influencing efficiency scores. Conclusion: To enhance transportation efficiency, particularly in road transport, priority should be given to investments that promote intermodal transport and improve system integration. Additionally, incorporating sustainability and environmental practices can significantly improve efficiency across all modes.
