ABSTRACT
as an important window of China's foreign economy, whether the port can achieve efficient operation has always been a highly concerned issue for the government and enterprises. To solve this problem, based on the traditional DEA model, this paper proposes a Super-SBM model considering the unexpected output such as environmental pollution. This model can reflect the importance of controlling the unexpected output by restricting the weight of different types of output. Finally, taking the major port enterprises in China as an example, this paper applies the model proposed in this paper to objectively evaluate the operation efficiency of major ports in China, and provides relevant improvement suggestions.
