Exploring the cargo and eco-efficiencies of international container shipping companies: A network-based ranking approach

This study aims to evaluate the cargo and eco-efficiencies of international container shipping companies (CSCs) for the period 2013-2017 for benchmarking purposes. An integration of two-stage network directional distance function and network-based approach in data envelopment analysis is utilized to distinguish the efficient operators. Results show that most CSCs are highly ranked in the cargo efficiency stage but lowly ranked in the eco-efficiency stage and vice versa. This study emphasizes the strengths and weaknesses of each factor of every CSC. Results can help the inefficient CSCs find the areas for improvement by learning from their peers.
