Purpose: This study aims to assess the efficiency in performance of 22 ports listed in Vietnamese stock market. Research design, data, and methodology: A hybrid method of AHP and Malmquist DEA was applied to handle the problem of efficiency measurement. The AHP method was employed to define the efficiency evaluation criteria whilst the Malmquist DEA was utilized to measure the performance efficiency. Results: The results showed that five input and output metrics including capital, operation expenses, labour, revenue, and cargo throughputs are important for port efficiency. In addition, it was also found that technology and management skills have great impact on the total productivity of ports. Conclusions: Comprehensive evaluation of port system in Vietnam may result in plenty of benefits to individual ports and the port authorities as well as in the course of port performance efficiency improvement. However, the study findings are only in compliance with the case of Vietnam. Thus, future research may be reached out to other regions or countries. The next limitation involves the small number of ports engaging in the empirical study from 2015 to 2021.
