Abstract

In order to improve the green development level of ports, the environmental efficiency of coastal ports is measured. This paper improves the port environmental efficiency evaluation index system, uses the super-efficiency SBM model considering undesired output to evaluate the environmental efficiency of 14 coastal ports in China from 2012 to 2020, and proposes improvement directions and paths according to the results. The research results show that the overall environmental efficiency of coastal ports is good, with an average value of 0.7847. According to the slack variable results of inefficient ports in 2019, the main reasons for port environmental inefficiency are low resource utilization and insufficient throughput. Ports should optimize resource allocation, deepen energy conservation and emission reduction work, and achieve green and sustainable development.
